In this video, neuroscientist Dr. Jang Dong-sun explains the science behind the superhuman abilities and indomitable mental strength of athletes who push past the limits of human performance. He explores how a brain region called the aMCC (anterior Mid-Cingulate Cortex) is connected to mental fortitude, willpower, and the ability to achieve goals, and discusses how anyone can strengthen this region to unlock peak performance.

1. Athletes Who Transcend Human Limits

Every four years when the Olympics roll around, national team athletes compete against the best in the world, producing astonishing records. Why are we so captivated by these athletes? Dr. Jang shares the anecdote of how Michael Jordan effortlessly surpassed the theoretical jumping limits that scientists had calculated, highlighting how athletes keep breaking records that never existed before. This superhuman performance that turns the impossible into reality is exactly why we are so drawn to them.

So is this ability innate, or is it built through practice? Dr. Jang explains that while natural physical attributes matter, there are many athletes who perform beyond their physical limitations. Korean athletes in particular often lack the height and size advantages of their competitors yet still deliver outstanding performances. He attributes this not simply to innate talent, but to a "system" that minimizes the impact of external factors and enables peak performance under any circumstances.

"You need processes that keep upgrading your skills, and the beauty of a good system is this: if the system remembers even the smallest improvement and can reproduce it, then every time you practice, you actually get better. Without such a system, practicing a thousand times blindly won't improve your skills at all."

Just as archery athletes train to stay unshaken even amid jeering crowds, elite athletes aim to build a system that ensures their learned and practiced skills function reliably regardless of weather conditions or emotional disturbances.

2. The Decisive Difference Between Pros and Amateurs

What is the decisive difference between professional and amateur athletes? It comes down to consistency. Top-level athletes have remarkably little fluctuation in their performance. Sustaining consistently high performance requires an excellent training system. An athlete's innate genetic abilities alone are not enough to produce peak performance; Dr. Jang emphasizes the importance of a training system where coaches, staff, and everyone involved work together to maximize and stabilize an athlete's capabilities.

3. Indomitable Mental Strength: The Secret of aMCC

Yet even among athletes who undergo the same training, some perform at a superhumanly high level. We typically describe them as having "incredible mental toughness" or "unbreakable willpower." While "mental toughness" and "willpower" are not scientific terms per se, neuroscience reveals that there are distinct differences inside their brains.

Professor Andrew Huberman, a well-known neuroscience communicator, gained fame for identifying a brain region associated with this mental toughness, willpower, and grit: the aMCC (anterior Mid-Cingulate Cortex).

"The brain region called the aMCC is far more developed in the brains of people with iron-willed mental strength and willpower -- the people who get things done."

Studies comparing the brains of people who successfully diet versus those who fail, and athletes who consistently deliver results versus those who don't, have found differences in the activation level and development of the aMCC region. High performers showed higher aMCC activation even when their minds were at rest. Dr. Huberman emphasizes that the aMCC is the very source of indomitable will, mental strength, and willpower.

4. What Exactly Is the aMCC?

Dr. Jang compares the aMCC, or anterior mid-cingulate cortex, to a "budget department inside your body that decides where and how much energy and effort to allocate."

For example, when you need to spend a lot of energy to learn a new skill, the aMCC is what decides whether to commit or not. It is also involved in focusing on priorities, initiating physical movement, and even the decision to endure pain.

If we compare the brain's energy to money, the aMCC is like a company's budget department. If that budget department is brilliant -- a true accounting genius -- it confidently funds new projects and encourages you through tough times by assuring you that good results are ahead. With such a stellar budget department, the company excels at new ventures, maintains focus, and weathers difficulties well. In the same way, if the aMCC is well-developed, it says "We can find the budget -- let's go for the goal!" and gives you the ability to turn the impossible into reality, even when things are hard.

Research consistently shows that in high-performing athletes and people with exceptional abilities, the aMCC region is thicker and more highly activated.

5. How to Strengthen the aMCC

Can ordinary people like us strengthen the aMCC region and become like those high performers? Surprisingly, the answer is simpler than you might think!

"When you truly don't want to do something, if you push through and do it anyway, that strengthens the aMCC."

When you accumulate small experiences of enduring and completing things you resist, the aMCC's activation increases and its neural connections grow stronger. For example, even if running is grueling, if you push through for just ten days of daily running, you strengthen the aMCC's connections not just through improved fitness, but through the very act of persisting through something you found unpleasant and difficult.

Dr. Jang shares what he tells his son when the boy says he doesn't want to do his homework:

"When you don't want to do something but push through anyway, the superpower region in your brain gets thicker. And what does it do? It gives you the ability to endure and persist no matter how hard things get. While other kids say 'This is too hard, I can't do it' and give up, you can say 'This isn't so bad' and keep going. That ability stacks up over time."

Superhuman patience doesn't develop overnight, but when you gradually push through discomfort and exercise patience to accomplish something toward your goals, these connections are permanently etched into your brain. Even if nobody knows or is watching, the aMCC region inside your brain grows thicker. And once it has thickened, the aMCC boosts your capabilities the next time around, transforming you into someone who can accomplish things without wavering.

6. Why Winners Keep Winning: The Winner Effect

Beyond strengthening the aMCC, there is another important reason why people who win once are more likely to keep winning: the "Winner Effect." Simply put, because the brain has experienced a victory, motivation kicks in even more powerfully the next time.

When something seemed nearly impossible but you pulled it off and thought "Wow, I did it!", the brain releases an extremely powerful dopamine reward. This reward strengthens the circuits that drive you to try harder and take bigger risks. It is as if the brain's budget department triggers a positive loop, saying "Alright, I'll give you more budget -- I believe in you!" Once this positive loop is established, it generates even more positive energy.

Grit, boldness, or in other words, resilience -- the brains of elite national-team athletes show higher resilience, greater connectivity, and higher neuroplasticity.

This Winner Effect is especially potent in underdog situations. When you thought you might lose but defeated a formidable opponent, we call it "riding the momentum." This experience raises the probability that you can defeat yet another strong opponent in the next match.

Conclusion

The kind of performance that turns the impossible into reality is not built overnight. It comes from athletes who build brain circuits through the belief that "if I push through this, I'll get better," even when they are exhausted, sleepy, and hungry. And the truly exciting news is that this is not exclusive to top-tier athletes -- everyone can strengthen these circuits and improve. Even when it is hard and challenging, pushing through strengthens this region of the brain and elevates your capabilities.

Dr. Jang sends an encouraging message to all athletes competing in the Paris Olympics, expressing his desire to applaud them for overcoming hardships and taking on the challenge, regardless of whether they win gold, silver, or bronze. He also emphasizes that the collective empathy and encouragement from fans is a tremendous source of strength for athletes. Positive feedback gives athletes the conviction that "I can do this -- with this much support behind me, the current pain is nothing. I can do even better!" -- helping them overcome any difficulty.

Keep pushing forward and may you achieve your peak performance! Fighting
