Neocortex

Most recently expanded outer layer (“new bark”) of the forebrain, composed of about six layers of gray matter. Its name is a misnomer, as it actually isn’t newer because it arose at the same time during evolution as other forms of cortex. It is also called isocortex because it is almost always six-layered, with few exceptions.
