Motor Cortex Flashcards
This area of the cortex for initiating saccades
frontal eye fields
Loss of function to one side of frontal eye fields leads to
loss of contralateral saccade movement
Why does the primary motor cortex neuron activate before movement?
preparation
What is the function of the dorsal premotor cortex?
reaching
More complicated movements come from which area of the brain?
premotor cortex
Feeding movements that have behavioral signifigance happens where?
premotor cortex
The loss of which brain area might result in not being able to respond to stimuli?
premotor cortex
Posterior parietal cortex has a lot to do with
vision
Supplementary motor area has to do with
internal generation of movement
Which area plans movements?
supplementary motor area
Which area is active in mental rehearsal?
supplementary motor areas
As tasks become highly proficient, activity in the supplementary motor area…
decreases
Patients become stimulus bound when you lesion which area?
supplementary motor area
Alien hand syndrome results from
lesion of supplementary motor cortex
What is utilization behavior?
use of objects in an inappropriate setting (excessive response to external stimuli) from supplementary motor cortex
