inability to understand body language and vocal social cues (ie. sarcasm)

Question 19

heteromodal association cortex

Answer 19

association cortex that receives information from 2 or more unimodal association cortices

Question 20

parietal-temporal-occipital association cortex

limbic cortex

Answer 23

• receives info from heteromodal association areas, cerebral hemispheres, and diencephalon
• involved in homeostasis, olfaction, memory, emotion
• sends info to prefrontal cortex to aid in decision making
