personality, behavior, emotions, and intellectual function
frontal lobe
initiates voluntary movement
precentral gyrus
primary center for sensation
parietal lobe
visual receptor center
occipital
auditory reception center
temporal
language comprehension, when injured, receptive aphasia results, the person hears sound but it has no meaning
