|
Definition
interprets color, form and movement
uses past experiences to enable us to comprehend what we are looking at (face recognition) |

| Posterior association area |
|
Definition
| recognize patterns and faces, understand written and spoken language, attention to an area of space or an area of one's body |
|
|
Term
|
Definition
| provides emotional impact that makes a scene important to us, includes hippocampus to establish memories that allow us to remember an incident |
|
|
Term

|
|
Term
|
Definition
receives input from whole cerebral crotex
important in performing several activities at one by inhibiting other movements
stops, starts, and monitors movement executed by the cortex |
