Chapter 3: Fore brain parts

Question 1

thalamus

Answer 1

• output to primary sensory cortex
• input from sensory organs

Question 2

basal ganglia

Answer 2

sensory association areas (performs movements to obtain rewards), and tied to pleasure centre

Question 3

damage to basal ganglia can cause…

Answer 3

parkinson’s, tremors, loss of motor control

Question 4

hypothalamus

Answer 4

regulates internal states, emotion and motivation, regulates sex, hunger, thirst, and body temp.

Question 5

limbic system

Answer 5

emotion, internal states (smell, motivation, memory, evolved out of olfactory system)

Question 6

what does the limbic system entail?

Answer 6

thalamus, hypothalamus, hippocampus, amygdala

Question 7

amygdala

Answer 7

damaged amygdala’s lead to no detection of fear.

Question 8

hippocampus

Answer 8

spatial memory, physical layouts/ mental maps
