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
T/F supplementary motor area separates frontal eye field and motor hand area
true
primary auditory area composed of
heschl gyri
where is primary auditory area
superior temporal gyrus
function auditory associate area
gives meaning to sound
primary gustatory area function
taste
where is primary gustatory area
insular cortex, lateral fissure
insular cortex function
consciousness, emotion, self awareness, cognitive function
Broca area where
frontal lobe
anterior to premotor association area
wernike area where
around lateral fissure and primary auditory area
function broca
production of language
function wernike
comprehension of language
what connects Broca and wernike
arcuate fasciulsu
arcuate fasculus allows what
produce words that make sense, under and respond
which hemisphere deals with important language functions
dominant
which hemisphere accent tone
non dominant
frontal associate area function
execution
memory, problem solving, planning, cognitive flexibly
parietal association area where
posterior to somatosensory area (post central gyrus)
purpose parietal association area
orienting our attention
temporal associate area for
link visual stimulus of face or object and meaning / identity
unimodal association cortex
higher order of single sensory or motor
adjacent to primary or sensory area
visual, auditory, somatosensory association, supplementary motor, premotor, language.
hetermodal association cortex
integration multi modality (sensory or motor )
frontal, parietal , temporal association areas
primary cortical area
specific function.
primary motor and sensory area.
primary areas for vision, hearing, taste, smell
