Question

The cerebral cortex is very wrnkled. How does the wrinkling make it more efficient

Answer 1

It’s this wrinkly surface, called the cerebral cortex, that puts us at the top of the intelligence mountain, essentially because by folding into wrinkles, more brain surface can fit into our skulls. More cerebral cortex equals more intelligence. The four wrinkled lobes of our cerebral cortexes are involved in higher-level processes like memory, perceptual awareness, thinking, language and consciousness.
