Why is the brain “wrinkly”? How does a larger surface area of the brain give us more of an advantage over volume?

In: Biology

Answer 1

The wrinkles are called cortical folds, which increase the surface area of the brain. The outer layer of the brain is actually where the neurons are, the internal parts of the brain are neuron connections, the rest of the grey matter, the internal “organs” (not actually), and gloopy stuff.

Having more surface area means more neurons, meaning there can be more of you.

EDIT: Typo, spelled cortical ‘corrical’

Answer 2

I’ve seen images of someone with a smooth brain somewhere… Think it was a genetic defect, but I don’t think it affected then mentally..?

I have no source, so cannot confirm

Answer 3

because the cores of your neurons are only located at the surface of your brain, the interiour consistd of their connections if im not mistaken. a larger surface volume leaves you with more neurons in total
