Q

role of cerebral cortex

A

voluntary actions
cognition
perception/awareness

basically stuff that makes u smart

37
Q

what type of cerebral cortex do mammals have compared to birds, reptiles

A

mammals: 6-layer structure (neocortex)
non mammals have 3 layer

38
Q

clockwise from front, name lobes and brief fucntions of cerebral cortex

A

frontal - voluntary actions
(somatomotor cortex)
(somatosensory cortex)
parietal - sensory info, language
occipital - visual processing
temporal - memory, language, sensory

39
Q

what is homunculous

A

map of the brain according to the neural composition

40
Q

decussation

A

word that describes how the right half of the brain controls the left half of the body and vice versa
