It's wrinkled convoluted appearance is due to a growth spurt during the fourth and fifth months of embryonic development, when the gray matter of the cortex is expanding greatly as it's cells grow in size. The supporting white matter, meanwhile, grows less rapidly; As a result the brain takes on the dense folds and fissures characteristic of an object with great surface area crowded into a small space.
