cerebrum Flashcards
what is the neocortex
6 layer outer cortex, based on grey matter of cerebral cortex
where is the central sulcus
in between the frontal and parietal lobe
where is the lateral sulcus
between temporal, parietal and frontal lobe
where is the parieto-occipital sulcus
in between the parietal and occipital lobe
where is the preoccipital notch sulcus
below the occipital lobe
what are the 3 functional areas types
motor sensory association
what are the functional areas in the frontal lobe
primary motor area
pre motor area
brocas area
frontal eye field
prefrontal area
which gyrus is in the frontal lobe
pre central
what is in the primary motor area
inverted motor homonculus
contralateral motor control
what is the homunculus
representation of body parts in the motor and somatosensory cortex of the brain.
lesion in the primary motor area will cause what
effect on the opposite half of the body
function of the premotor area
programmes the activity of the primary motor area
where is the premotor area
anterior to primary motor area
lesion in the pre motor area will cause what
a difficulty in performing skilled movements
function of frontal eye field
connects voluntary eye movements to opposite side
what is the frontal eye field connected to
visual cortex by association fibres (involuntary)
a lesion in the frontal eye field causes what
inability to move eyes to the opposite side
functions of pre frontal area
personality, behaviour, judgement
a lesion in the prefrontal area causes what
changes in personality and inappropriate social behaviour
what are the functional areas of the parietal lobe
primary sensory area
wernickes area
which gyrus is in the parietal lobe
post central
function of the primary sensory area
contralateral sensations
lesion in the primary sensory area causes what
contralateral loss of sensation
what input does wernickes area receive
somatic, auditory and visual area
