Here is what they found.

Your brain basically has several spurts or key periods of development across the lifespan.

And in each of those periods, different things are occurring.

The four turning points that we need to know are ages 9, ages 32, age 66 and age 83.

So between 0 and 9, your brain is just like building as much as it possibly can.

It's growing very, very rapidly.

between 9 and 32, which they actually, they call the adolescence period, even though it's not just the teenage years.

That is when your brain starts to prune.

It starts to build different neighborhoods of neurons and thought processes, and it integrates those neighborhoods.

It gets really, really organized.

It starts to kind of get closer to optimizing and gets closer to being able to reason through all of its thoughts.

Between 32 and 66 is when it gets the most efficient and it begins to specialize.

Basically, things start to really feel locked in.

That's when we're perfecting pathways.

After 63, the core areas of our brain and those core pathways become more important.

All the other like kind of medium and small important pathways around.

and different circuits become less important.

So basically it's organizing and it's consolidating even deeper.

And after the age of 83 is when we see a lot of neural decline, loss of gray and white matter.

And it's when we see central pathways really become the main pathways.
