Root Explanation

Neocortex → It is formed from "neo-" (from Greek "neos", meaning new) and "cortex" (from Latin "cortex", meaning bark or outer layer). The word "neocortex" refers to the new outer layer of the brain, which is involved in higher-order brain functions.

Memory Tip

Think of 'neo-' meaning 'new' and 'cortex' referring to the 'outer layer' — the neocortex is the new outer layer of the brain responsible for complex functions.
