Dr. Wendy Suzuki

You get brand new brain cells born in your hippocampus, just deep in this region right here.

that make your hippocampus, as I like to say, big and fat and fluffy.

How often are they born?

They're born regularly.

You can be a couch potato and you get brand new hippocampal cells.

However, with exercise, you are feeding the hippocampus and your brain growth factors.

And the growth factors make more of those hippocampal cells grow.

We know from lots of experimental studies that that causes significant improvement in your memory.

Yes, absolutely.

Not everybody has seen a real brain.

We all have one.

Yeah, everybody should see their brain, says the neuroscientist.

But it is a structure just like the body.

It is benefited by many things that you can do in your life.

And I like to remind everybody,

that the human brain is literally the most complex structure known to humankind.

I'm going to say that again.

It's the most complex structure known to humankind.

We still don't understand, after 100 years, over 100 years of studying, all the capacity there.

Why?
