Cerebral Cortex

Answer 2

most evolved part of the brain. Involves our higher over thinking process and our sensory perception areas there are 4 lobes in the cerebral cortex

Question 3

Frontal

Answer 3

controls personality, decision making, aspects that make us who we are

Question 4

Motor cortex

Answer 4

in the frontal lobe, controls all voluntary movement. Right side of body controlled by left motor cortex and vice versa.
