cortex Flashcards
cortex divided into
primary and association areas
primary cortex area
receive sensory info
execute motor task
association area
higher order processing
integrate, interepret
uni or heteromodal
examples primary cortical areas
motor area somatosensory visual auditory gustatory area
example of associate areas
pre motor somatosensory auditory frontal pariteal / sensory tempora
where is primary motor area
pre central gyrus of frontal lobe
primary motor area responsible for
motor output to contralateral side
what makes coricospical trac
outflow from primary motor area
where is supplementary motor area , premotor association area located
anterior to primary motor in frontal lobe
T/F is supplementary motor area superior or inferior
superior
supplementy motor area contains
motor maps for posture
where is somatosensory association area
adjacent to primary somatosensory area of parietal
whats somatosensory associate area do
interpret significance of sensory info (touch pressure proprioception)
primary somatosensory area where
post central gyrus of parietal lobe
wheres primary visual cortex
calcarine sulcus (medial occipital lobe)
how is primary visual cortex organized
retinotopically
fibres from upper visual field where on calcarine sulcus
lower
fibres from lower visual field where on calcarine sulcus
superior
region of highest visual acuity in retina
fovea
where is fovea
near occitiapl pole
where is visual association area
surround primary visual area
whats more posterior, primary or association visual area
primary
where are frontal eye fields
supplementary motor area
motor hand area located where
posterior to frontal eye field
