On January 13th of 1982, Air Florida Flight 90 crashed into the 14th Street Bridge, plummeting into the icy-cold Potomac River just a few miles from the White House. The impact of the collision killed 73 people, leaving only 6 survivors struggling to survive as the military and surrounding civilians attempted to rescue them. When the rescue chopper arrived, Arland D. Williams, one of the six survivors, unselfishly passed the rope to the other survivors three times, putting their lives above his own. Sadly, he didn’t make it and drowned in the icy depths.

And something just as unselfish and inspiring occurred on January 2nd of 2007. Commemorated as the “New York City Subway Hero,” Wesley Autrey, a 50-year old construction worker at the time, performed an unselfish, heroic act by leaping onto the tracks of a subway rail to rescue a young man who had convulsed and fallen in. With no time to think, Autrey sprang into action, leaving his two daughters on the platform, and pressed his body against the fallen man’s as the train went over their heads, failing to brake in time. Thankfully, both men survived and made it out with very minor injuries.

The actions of Williams and Autrey are honored as valiant, altruistic acts. But what is altruism, what motivates people to perform such acts, and what is the science behind it?

Altruism, simply put, is the unselfish act of helping someone out of concern for their welfare and wellbeing, often at a cost to oneself. Altruistic acts are characterized as actions that aren’t motivated by any form of personal gain, duty, responsibility, loyalty, or any other such reason. The act is performed purely to help someone else out of the good of your heart. There are no expectations of rewards (prize money, awards) or ulterior motives (wanting to be seen as a hero or famous).

The term “altruism” was first coined by the French Philosopher Auguste Comte to encapsulate his vision for morally putting the needs of others before one’s interests. He constructed the word from the Latin “alteri”, meaning “others”, and since then the word has been interpreted and defined in many ways- including both the ulterior and non-ulterior senses of the word. Auguste Comte’s time has come and gone, but the conundrum that his concept has caused still ripples throughout society today.

Now, if this seems pretty idealistic, superhero-esque, that’s because it is. Or at least, that’s the debate that rocks psychology. From an evolutionary point of view, there is no logical or rational reason for a person to help someone else, especially by risking their life or a similar personal cost. Thomas Hobbes wrote in Leviathan that humans are inherently selfish, and all altruistic acts secretly had some self-interest at heart. The famous 18th-century philosophers David Hume and Jean Jacques Rousseau, argue the opposite.

So are some people really filled with such a selfless, make-the-world-a-better-place type of attitude?

Well, there are essentially two perspectives on altruistic acts: self-interest (egoistic) and selfless (altruistic).

Let’s delve into both:

The egoistic perspective, defined by Psychological Egoism and rooted in the Theory of Universal Egoism, states that every action has an underlying self-interested or self-benefiting motive that drives the action itself. And this isn’t necessarily always explicit or conscious. Within the realm of altruistic acts, the egoistic perspective argues that we help others not because we are innately selfless, good people, but because we have something to gain from it (could be subconscious, shaping our behavior without us being aware of it). For instance, we “selflessly” help a stranger because the action makes us feel good about ourselves, or increases our self-esteem and self-image, or impresses those around us, filling our need for attention or respect, or simply because we want to gain the person’s favor for future purposes.

From this perspective, there is no true altruistic act in the world since everything can be defined as having an underlying, self-interested motive. And the logical fallacy that courses this perspective is that it is unfalsifiable. It is merely an empirical statement because you can’t ever disprove that someone didn’t act for self-interested motives, especially if they aren’t even consciously aware of it.

On the other side of the coin, we have the altruistic perspective, which is shaped by the philosophical/ethical doctrine of moral or pure altruism. In moral/pure altruism, only a single motive exists and drives the action—the welfare of the other person. Pure altruistic acts are driven by a person’s internal, selfless values and principles to do good and benefit others, even if it’s risky or comes at a personal cost. This remains more of a philosophical concept than a psychological one.

It’s unlikely that Auguste Comte was expecting such an age-old debate about altruism to rise when he first conjured the idea of it- but since his simple definition was created there have been philosophical, political and biological arguments on whether humans are naturally selfish or unselfish that continue today, as well as a hundred different takes on the meaning of altruism and the types of actions that fall under the word.

Psychologists have found there to be many actions that fall under the term “altruism”, categorizing them into three distinct types.

1. Genetic Altruism – In this type of altruism, people engage in altruistic acts that explicitly benefit family members, such as when parents make millions of sacrifices for their children’s happiness and future. From an evolutionary standpoint, genetic altruism makes the most sense. Evolutionary theorists maintain that we essentially focus on the genes over the person itself. By helping our family, people who share our pool of genes, we are increasing their chances of survival and thus, ensuring there is a greater chance for the genes to be passed down in the future. This is also known as kin altruism or inclusive fitness theory.

2. Reciprocal Altruism – Reciprocal altruism involves an expectation that others will eventually offer their help in return if you help them now. For instance, you help your classmate with a problem today, assuming that they will one day reciprocate your act by helping you with something else. But why would we selflessly aid a stranger with whom we don’t share much genetic material? Evolutionary biologists argue—it does. By helping a stranger in exchange for future mutual aid, we increase the chances and possibilities that we or our kin receive the benefit in the future. This concept is mathematically established through a broad field known as game theory. So by helping someone, you increase your possibilities for future reciprocal aid when needed for yourself and your genetic family.

3. Group-selected Altruism – As the name indicates, in this type of altruism, people engage in altruistic acts for only people within their “group,” which may be based on familiarity, friendship, gender, age, interests, hobbies, or virtually anything else that unites a group. People feel loyal and obligated to their group (akin to a social family) and thus perform selfless acts for people within their group.

But with all the theoretical talk about what altruism really is, and how it is defined, another topic entirely is why people decide act altruistically. After all, one of the most inquisitive questions psychology strives to answer is why we do what we do. What drives our actions? What motivates us to be altruistic (if we assume such an act exists, and not everything is egoistic). Scientists have come up with a couple explanations, but these are just the beginning.

1. Evolution/Kin Selection – As mentioned in previous paragraphs, evolutionary scientists believe helping those who share your genes increases their chance of survival in the future, and thus passing down their genes in the upcoming generations and pass on the lineage. Thus, evolution has made family-based altruistic acts a part of our instincts and nature.

2. Reward Center – Neurobiologists have discovered that when people act altruistically, the reward centers of their brains become more active, supplying them with a sense of pleasure and contentment. Participating in altruistic, compassionate behaviors activates these pleasure centers in our brains and the positive feelings that result then reinforce our altruistic behaviors, leading to a cycle.

3. Environment – Altruistic acts fall under the broader umbrella of prosocial behavior—socially conforming and accepted behaviors intended to help other people. And a ton of research suggests that prosocial behavior has a nurture-based effect. The environment you inhabit, the social interactions you have, and what you observe others do have profound effects on learning and participating in prosocial behaviors, such as altruism. The environment and social modeling, originating from Albert Bandura, have significant effects on prosocial behaviors and altruism.

4. Empathy – Centered around the empathy-altruism hypothesis, people who feel empathetic towards the pain or distress the person in need is in are more likely to engage in altruistic behaviors. Neurobiology research also reveals that mirror neurons allow us to feel and “mirror” the feelings and emotions of those around us. When we see someone in need, we naturally share some of the pain they are undergoing, feel it internally, and this acts as a motivator to participate in altruistic actions. The negative-state relief model affirms that altruistic acts help alleviate the negative feelings we experience when we see someone in distress or pain. We experience negative emotions when we see someone suffering, and we feel better (by reducing these negative emotions) by helping them.

5. Inner Cognitive Incentives – We often help others “selflessly” because it makes us feel better about ourselves. Essentially—acting good makes us feel good. An egoist would claim that the act isn’t truly altruistic since there is an incentive to make ourselves feel better (self-benefiting).

Whatever the reason people decide to help one another out, altruistic acts promote prosocial behavior in society, self-motivated or not. Society runs on the back of people being kind to one another, and without the occasional altruistic act, people would have many more problems than we do today. Thats not the only benefit of promoting kindness in everyday life, however. Altruistic acts committed can bring about many benefits, both on an individual scale and a large one.

1. Better Physical Health – First and foremost, an array of research clearly outlines that altruistic acts can not only improve our physical health (ex–reduced stress levels & risk of high blood pressure) but also significantly lower your chances of mortality

2. Increased Happiness – People also tend to feel more satisfied, content, and happier when they engage in prosocial behavior motivated by others’ wellbeing. In fact, a famous research study revealed that people feel happier when they spend money on someone else rather than themselves.

3. Improved Mental Health – Similar to volunteering, engaging in altruism alleviates stress, calms anger, and counteracts anxiety. Moreover, engaging in volunteering and prosocial behaviors can help with depression, increase confidence, and prevent feelings of isolation.

Altruism imbues the person you are assisting and you with joy, peace, and life! Helping someone out helps you out more than you realize.

However, a precautionary note: be wary of being altruistic to such an extent that you are putting yourself in significant and permanent harm or risking your life.

So what does all of this mean? Everyone comes to their own conclusion. Some people believe there is no such thing as altruism or selflessness and see all acts of aid as self-benefitting ruses. Others believe that people are good by nature and are deeply caring and nurturing of others. Philosophical, theological, and even biological debates on Auguste Comte’s vision of altruism have prevailed for centuries- and they don’t look like they’re stopping any time soon. It’s up to the people to research, learn, and form opinions on their own.

Well, here’s ours: regardless of your motives, whether it’s completely idealistic, founded on pure principles, and has no lustre for self-benefit or it’s entirely selfish for reasons like feeling better about yourself or improving your image for the press, a good deed is a good deed in the end. Despite the underlying reason, the outcome is the aid of someone in need. And as such, we ought to focus more on the effects and results of our actions and appreciate the support we can give someone.

So, go out there and be more compassionate, generous, and altruistic! For decades to come, people will still debate the true intentions of Arland Williams and Wesley Autrey, but one thing is certain. Regardless of why they did what they did, real people are alive and living real lives because of their actions.

And that’s all that matters at the end of the day.

Note: In acknowledgment of his bravery and sacrifice, President Reagan recognized Arland Williams as a hero. He may no longer be alive, but by renaming the bridge Air Florida 90 crashed to Arland D. Williams Jr. Memorial Bridge, his actions are memorialized for history.

Our world is full of colors and creative interpretations of life. Whether it’s perspective on artwork, mathematics, or even simple daily objects – our brain constantly uses its creative cognitive thinking, allowing us to view the different perspectives that are comprehensible to our brains. Let’s take a look at how this creativity in the brain develops.

Creativity isn’t a single process, with a simple mechanism. Creativity is something that changes per person. To put this into perspective, think about your version of an amazing looking cupcake. Strawberry frosting, rainbow sprinkles, and a cherry-on-top perhaps? Each person’s perspective on this cupcake would be different, because the factors that you are adding to make this cupcake look so good is none other than your very own creativity. Creativity can come from various factors, and is one of the most complicated human behaviors.

Contrary to popular belief, where various individuals believe that creativity only comes from one select part of the brain – the human brain actually does not have one single creative center. In fact, all parts that you are about to learn about all contribute to your creativity. Without one region, the rest cannot function to properly perform the creative process. Let’s start with the frontal cortex. The frontal cortex region of the brain is responsible for various processes of creative thinking, and is also known as the hub of creativity. Think about it like the base of your creative and wide-spread thinking!

Next comes the hippocampus. This region of the brain is best known for storing information and memory in a safe way, allowing you to recall most essential needs with a quicker method. According to frontiersin.org, “In the creative process, similar to remembering experiences by pulling together different parts of the experience, the hippocampus may be used in imagination to pull together ideas in ways that you have not thought of in the past.” Two other regions that contribute to your brain’s creativity include the basal ganglia, as well as the ‘white matter’. The more the well-connected and proper functioning brain, the better and more creativity you get during your day to day life!

So next time you ever need or feel your creative juices flowing throughout your brain, just remember the hard work that your brain does to keep these creative functions healthy.

Most people believe that dementia is a disease but it actually is used to describe the decline of a person’s mental ability. Dementia incorporates related diseases such as Parkinson’s, vascular dementia and Alzheimer’s (most common form of dementia).

The brain is packed with around 100 billion neurons which are all interconnected, scientists call this a ‘neuron forest’. This means that it is very easy for signals to take place between nerve cells (aka neurons). When neurons are attacked or destroyed, they cause memories to fade, the inability to think properly and difficulty in expressing feelings. This can then lead to diseases such as dementia.

Neurons don’t regenerate unlike other somatic cells so Alzheimer’s (which is a disease that destroys the brain’s neurons) can affect all areas of the brain. Certain groups are more susceptible to dementia, these include people who smoke, people who have diabetes and people who have obesity. This doesn’t mean that those individuals will necessarily develop dementia but it means that they have a slightly higher risk.

There are ways to combat dementia such as sleeping well, eating healthy, reducing stress, exercising and playing challenging games such as sudoku or scrabble.

Alzheimer’s disease is thought to be caused by an abnormal protein build up in and around brain cells. Amyloid is one of the proteins involved, and deposits of it create plaques around brain cells. Tau is the other protein, and deposits of it form tangles within brain cells.

Although it’s not known exactly what causes this process to begin, scientists now know that it begins many years before symptoms appear.

As brain cells are damaged, there is a decrease in the chemical messengers (called neurotransmitters) that are involved in sending messages, or signals, between brain cells. Acetylcholine levels are notably low in the brains of individuals who suffer from Alzheimer’s disease.

Different parts of the brain diminish throughout time. Memory is frequently one of the first areas to be impaired. Different parts of the brain are affected in more rare forms of Alzheimer’s disease. Rather than memory impairments, the earliest signs may be issues with vision or language.

Language is something that is necessary in today’s world. Whether you may speak English, Spanish, or any other of the hundreds of languages in the world – we all know and speak at least one language in order to communicate with others. When we were all younger, we were taught and trained to speak in a specific manner and language – it was practically a ‘requirement’ to know how to speak properly. But obviously, someone (or in this case, something) has to memorize that specific language – who, or what, is that special power that helps all human beings memorize their respective languages?

You guessed it – it’s the human brain!! From the very second we are born, our small baby brains learn to process movement, language, and emotions. Everyone considers baby “language” to simply just be babbling and random “noises”. Soon enough, however, those very same children learn to differentiate between noise, and actually language. In addition to this scientific brain process, there are also factors that come into play when talking about learning a language – such as time, grammar, emotion, and mood.

“What’s the process of this amazing function of translating to a language when you are so young” – you may ask? Well, the left hemisphere of the brain is responsible for the memorization and learning concepts – specifically in the Broca area, and the Wernicke area. These areas of the brain were both named after two scientists who have discovered and explored more about these parts of the brain and their functions.

Let’s go more into depth. The Broca area of the brain is responsible for the language parts and processing, especially when young children are just learning how to say their first words! This area also allows the brain and your body to see through and from specific memories and moments – which eventually allow you to speak fluently, indirectly! The Wernicke area of the brain allows your mind to see perceptions, different perspectives, understandings, and other characteristics of that language.

Language is not just something simple where your brain automatically seeps the knowledge in – it’s a process which takes time, effort, and a lot of brain power!

Sugar is something that we all consume on a daily basis – whether it’s through ice cream, cookies, or even coffee. Though our brains do require glucose (sugar) to use as energy – just like any other circumstance, overeating this sweet molecule may create quite the issue.

Our brain has various effects and powers that we use daily, including memory, color vision, and so much more. If our brains hold such important information that we must use daily, then it’s our job to take care of it! “Brain food,” as some people call it, consist of vegetables, fruits, vitamins, and minerals that allow your brain to think clearly and have control over your senses. An overdose of sugar, however, is quite the opposite, as it decreases our cognitive thinking skills, control, and decision making strategies. Think about it like feeding a plant with fertilizer. The plant desires fertilizer to grow bigger, but too much can cause an overdose – resulting in worse issues such as drooping.

In a similar manner, consuming even the smallest amount of sugar can result in craving for more, resulting in long term issues such as weight gain, obesity, diseases, and more. This also includes memory loss and other vital functions- parts of the brain that we need daily, but are getting ‘spoiled’ because of sugar consumption.

Neurotransmitters, according to Google, are “a chemical substance that is released at the end of a nerve fiber by the arrival of a nerve impulse.” For instance, dopamine is an essential neurotransmitter that controls our mood, behavior, learning capabilities, memory, and more. When sugar (glucose) enters our bodies, certain neurotransmitters that are essential to daily ‘thinking’ and usage get harmed greatly, which can also result in sugar addition because of the harmed neurotransmitters.

Though sugar is something we practically cannot live without, there are always ways to control the intake of sugar in your brain and body, to maintain a healthy brain and positive mind. In addition, though sugar intakes are never suggested at high levels, there are always ways to control your BMI, and mental health, such as exercise.

Water – it’s something that we drink every single day, but don’t even realize the breathtaking results that our bodies perform to keep each cell healthy. Hydration is vital to survival as a human, and without it, the results would be quite clear to your body. Everyone tries their best to have a well-hydrated body, but do we focus on a well-hydrated brain?

Hydration is crucial for a well-functioning brain, and water allows the different parts of our brain to make important yet crucial decisions in our day-to-day lives. Suppose you are studying for a test, and putting your brain hard at work to memorize key terms, or other essentials that you need to understand. When your brain is hydrated, it can think properly and requires less effort to make the right, sensible choice as opposed to making your brain work 10 times harder, for the same results simply because of dehydration. The simple act of drinking water allows the brain to maintain optimal function, as the results of proper hydration throughout your days are mind-blowing!

The majority of the human brain is made up of 80% water – shocking! Therefore, our brains would be the first out of the whole human body to start to feel the effects of dehydration. By protecting your brain and drinking enough water, you would be doing a large favor to your body by allowing it to function properly and not show negative effects such as headaches, migraines, or even serious health damaging issues. In addition, concentration drastically improves with hydration, as “Staying properly hydrated enables the brain to stay alert so we can keep our attention and focus,” according to primowater.com. In addition to these benefits, hydration also allows your brain to have balanced moods, get rid of unnecessary mood-changing hormones, get rid of toxins and dead cells, as well as balance chemical processes! By keeping your brain and body cells active, you are indirectly providing your brain with essentials that allows it to perform at its very best! So the next time you want to memorize something important, do essential work, or just need a brain-booster in general, remember to give your brain the water it needs.

Have you ever had to study really hard for a test or finals, and perhaps memorize tons of different terms and definitions? Maybe you had to memorize a musical piece for a performance, or maybe even instructions for a specific procedure. In all of those cases, memory is something that you would definitely need in your day-to-day life. But where does this superpower of immediately remembering terms come from, especially after learning about it just a few times and being able to instantly recall those actions? You guessed it – it’s none other than the brain.

Memory isn’t something that just magically appears in your brain, and you definitely can’t force your brain into remembering something. The recollection of a certain memory or idea comes from a certain part of the brain that you may have heard of – the hippocampus. This complex structure in your brain plays a major role in memory and learning new things to remember them. The hippocampus allows you to process and receive two different types of memory, which include spatial relationship memories, as well as declarative memories. When you remember or are trying to memorize a route from Point A to Point B, your spatial relationship memory is the function that helps you to recollect these points. Declarative memories, however, are hardcore facts such as events, definitions/terms, or even speeches/sentences. With these major roles that the hippocampus plays in your everyday life, hippocampus damage is rather dangerous. Hippocampal damage can permanently remove one’s ability to remember good times or memories, as well as extremely essential dates or times that they need to keep stored in their brains.

To further explain the truly magical phenomenon of memory and remembering information, chemical and electrical signals also play a major role in this function. Memories are stored in these signals, as your nerve cells also connect together to create certain synapses, which is a junction between two nerve cells. Whenever you are in a situation where you urgently need to recall past memorizations or data – such as a speech, competition, or even during a test – these synapses snap right in place and your brain triggers these special forms of memory. Therefore, these cells in your brain work extremely hard to ensure great memory and longer recollection time, making your brain as efficient as possible!

Procrastination : whether we realize it or not, it’s something that all humans tend to do. ‘Maybe later’ or ‘It’s not even due soon, I’ll just start it later’ are terms that we’ve probably said, and have definitely regretted. When people think about procrastination, the first term that comes to mind is laziness. Our mental lethargy and negative attitude towards a task may definitely affect the end result of our work, but procrastination is actually nothing related to laziness. The act of dithering our prioritization actually finds its roots in our deeper biology : the brain.

Procrastination is in fact the result of a constant duel in our brain between the limbic system and the prefrontal cortex. Try thinking about this combat as a wrestling match. Let’s introduce our wrestlers. Team A, the limbic system, also has a nickname, the Paleomammalian Brain (you can call him Pal). Pal, or the limbic system is one of the oldest, strongest, and most dominant portion in the brain, making him much more powerful in this wrestling match. Whenever his complex system desires to make a move, it happens automatically. When Pal’s team, or your body in the case of reality, is telling Pal to flee from the situation that he feels uncomfortable or unpleasant in, Pal is actually the one making these moves. It is his words that are making them feel these thoughts, as the limbic system is also tightly connected to Team B, the prefrontal cortex.

Now, it may seem rather peculiar that rivaling teams are right next to each other! Actually, the prefrontal cortex and Pal are very different parts of the brain. To add on, scientists predict that Team A and B like to believe that they should “keep their friends close, but enemies closer.” Anyways, the prefrontal cortex (P.C.) is a much newer and less developed function of the brain, making it somewhat weaker in this battle. However, the P.C. still does play an essential role in this battle: Procrastination. The prefrontal cortex’s role in the complex system of the brain is to plan complex behaviors that are planned to happen, expressing Team B’s personality, and making decisions for the team (or in the case of reality, your body!)

Since the Pal, or the limbic system, had much more advantages and strengths compared to P.C., or the prefrontal cortex, it very often wins the battle of the brain! However, the outcome of this victory may not be so pleasing to the body. The limbic system’s victory often symbolizes none other than procrastination. Though our brain gives us what we want currently, procrastination definitely is not what we wanted to do in the future. Therefore, procrastination is often seen as the battle between your present mind, and future mind.

Although many scientists and neurologists agree that procrastination is definitely not a good habit to develop, you should never be greatly discouraged or depressed if you’re a master procrastinator. Just remember, it’s perfectly normal for procrastination to occur, since it is rooted deep in our very own biology and neurology.

Words and actions are something you can never retract. Try picturing this : you just walked out from your friend’s house, with your head down in disappointment and embarrassment. Your words have hurt your friend more than you’ve ever hurt anyone, and you truly didn’t mean to misuse your words like that. Your mind keeps thinking back to what you said, and you just wish that you could somehow go back in time to retract your actions. Does this sound familiar to you? If so, you’ve experienced the terrible sense of regret.

Although many people try to forget about their regrets in the past, it’s definitely not an easy task. As you continue to ponder about why your brain reacted in such a hurtful or negative manner, regrets are considered to be bad decisions that someone has taken. When you continue to fill your mind up with these negative thoughts, it is known as counterfactual thinking. According to google, “Counterfactual thinking is a concept in psychology that involves the human tendency to create possible alternatives to life events that have already occurred; something that is contrary to what actually happened.”

As obvious as it may seem, there is a clear difference between regret, and disappointment. Though it might seem rather confusing at the beginning, experiences definitely teach an individual how to act based on their decisions and situation, whether it is positive or negative.

But how would this relate to the brain, you might ask? When you have a sense of regret, regions that are sensitive to your individual emotions activate in great amounts. Specifically, the orbitofrontal cortex (an area of the prefrontal cortex) as well as the amygdala (a core fear system in the brain and body) have a greater sense of activation when you have a feeling of regret, when compared to disappointed or depressed emotions.

In addition, the sense of regret is only caused because of a bad/poor decision you might have taken. In other words, this depressing sense develops when you have two or more choices that you must choose from, and your brain gets overwhelmed during your train of thought. When your brain decides to take the more effortful option : rejecting the option that was originally given to you in your decisions. This process of overwhelming decisions in your brain involves a particular area of the basal ganglia in your brain. This region takes part in making your decisions, and plays a major role in the sense of regret.

Next time when you have various paths of decisions that you are allowed to take, remember to truly think about what you, your brain, and your heart would desire : you definitely would not want to deal with regret.

It is a known fact that our eyes move faster than our brain is able to comprehend. Thus in order to compensate for this lapse, our brain has the remarkable ability to “predict” what our eyes will see next. Until recently, this phenomenon was largely unexplainable; however, research in the University of Scotland has determined how this process unveils, and how, in a sense our brain has the ability to work as a crystal ball.

Published in the Scientific Reports journal, scientists at the University of Glasgow in the United Kingdom had previously used functional magnetic resonance imaging (fMRI) and optical illusions to better understand what’s occurring in our brains when we see. As it is already established that our eyes transmit information to the brain through the optic nerve — a process known as feedforward input — the study particularly focused on brain feedback input, which is the neurological process where the brain sends information to the eyes. According to the study co-author Gracie Edwards, “Feedforward and feedback information interact with one another to produce the visual scene we perceive every day.”

The study utilized twenty seven volunteers; the fMRI focused on their visual cortex — the area of the brain involved in processing vision — while the volunteers viewed an optical illusion. This illusion entailed looking at two, stationery flashing squares; however, it appeared as though one square was moving between two locations. Results demonstrated brain feedback — they revealed that during the flashes, the visual cortex feedback updated to a new predicted coordinate; fMRI scans also showed that our brains simultaneously adjust predictions as our eyes move. These results were crucial, as they added to our existing understanding of neuroscience and the brain’s fascinating ability to predict future acts. To keep our vision “smooth”, our brain must foresee the location of a moving object; the study’s results allowed researchers to observe this mechanism directly.

Although this discovery is exciting by itself, the possible implications of it is even more exciting. For instance, knowing how the brain processes vision could eventually help us create brain-inspired forms of artificial intelligence. Currently, artificial intelligence uses a feedforward mechanism where it collects information and processes it in a main computer. However, it lacks a feedforward predictive mechanism. Incorporating this could unleash the gate to more breakthroughs in artificial intelligence, as well as allowing it to become more robust and flexible. Some experts warn that we should take a grain of salt with these discoveries, though; in other words, just because we could do something, it doesn’t mean that we should. Granting robots the intelligence equivalent to the human brain could lead to the beginning of the end for humanity.

Nonetheless, it is crucial to learn as much about the brain as possible, because in the long run, this knowledge could aid in treatments for brain injury or other neurological ailments. Our brain doesn’t work exactly like a crystal ball, yet, the fact that it could foretell objects seconds before our eyes glance at them is a testament to the power of the human brain, and the intricacies of the human body.
