TED Talks Daily · Feeling stressed? The answer isn’t to “just relax” | Aditi Nerurkar · 28 Apr 2025 podcast

And that prefrontal cortex governs things like memory, planning, organization, strategic thinking, complex problem solving.

In layman's terms, it's adulting right in the truest form.

But I will also add that your prefrontal cortex doesn't fully form until you're 25 years old.

And so up until 25, that prefrontal cortex is still being, you know, it's plastic, it's still changing.

There's an element of neuroplasticity that continues all the way through, all the way through our life.

Now, that's the prefrontal cortex.

Now, when you are under a period of stress, your brain is governed by another region called your amygdala.

And your amygdala is a small almond-shaped structure

deep in your brain that is truly cave person mode.

In fact, we in science call your amygdala reptile brain, because while other parts of your brain have evolved and changed through millennia, that reptilian brain is the same as it was when we were all cave people.

And what does the amygdala do?

It is focused on survival and self-preservation.

It is where the fight or flight response originates.

And so your brain is expertly designed, Ken, to handle short bursts of stress.

However,

Because back when we were all caves people, you would see a tiger in the forest and you would either fight the tiger or you would flee, you would run away.

That's where the fight or flight response comes from.

There are certain biochemical things that happen when you are engaged in the fight or flight response.

Your pupils dilate, the blood shunts away from your vital organs to your muscles.
