General features of the forebrain, including 3 major parts. Disease condition that is characteristic of these structures. The neocortex - creates reality a. b. c. d. There are some people born without a cortex (acephalic) or with a small one (micocephalic) Gene involved in this (beta-catenin gene) which is a mutation that causes the heads and brains of some people to be smaller than normal. In mice, the brain grew to almost double usual size with a souped up beta-caratine gene, developed sulci and gyri. May model some kinds of autism spectrum disorder.
