The Cerebral Cortex
Captions available
The idea
The cerebral cortex is the folded outer layer of the forebrain where perception, language, and reasoning are carried out.
In practice
The folds pack a surface area far larger than the skull would otherwise permit into the available volume.
Where people slip
Cortical thickness is a few millimeters. Nearly all of what is called thinking happens in that shell.
