cerebral hemisphere Flashcards
what are basal ganglia
collection of neuronal cell bodies buried in the white matter
what is a sulcus
dip in hemisphere
what is a gyrus
elevation of hemisphere
what is a fissure
deep sulcus
corpus callosum
bridge between the two hemispheres
what function is controlled by the frontal lobe (precentral sulcus)
motor functions
what functions occurs posterior to the central sulcus
sensory functions
what is area 4
primary motor cortex- somatotropin representation of contralateral half of body
what is area 44/45
brocas area of motor speech
what is area 3,1,2
primary sensory area in post central gyrus.
function of inferior parietal lobule
interface between somatosensory cortex and visual and auditory association areas
function of sensory parietal lobule
Interpretation of general sensory information and conscious awareness of contralateral half of body
Parietal lobe lesion
hemi-sensory neglect, can’t distinguish between right and left
what are areas 41,42
primary auditory cortex- superior temporal gyrus
where do you find the auditory association areas posterior to 41,42
crucial for understanding of spoken words.
