Q

tectum and tegmentum - where and what are they

A

midbrain
tectum - orientation after recieving info from eyes, ears and skin like turning to noise
tegmentum - movement and arousal. abundance of dopamine neurones - pleasure seeking and motivation

A

emotional processing and memories
attaches significance and other senses with events

18
Q

basal ganglia function

A

direct intentional movement

19
Q

what does the occipital lobe do

A
  • process visual info
  • primary region extracts simple regions then sent to frontal
20
Q

parietal lobe function

A

responsible for touch - containing somatosensory

21
Q

what does the frontal lobe do

A

movement, thinking, planning, memory judgement
has the motor cortex and mirror neurons

22
Q

temporal lobe

A

hearing and language with primary auditory cortex
secondary areas process info into meaning
