primary motor area for finemovements and spinal stretch reflexes
primary somatosensory areas for stereognosis tactile localization discrimination temperature and proprioception
somatosensory association cortex recieves fromsomatosensoryarea1 and somatosensory area2thalamicnuclei and limbicsystem and visualsystem and interpets them
premotor cortex initiates gross movements and involuntary movements with the basalganglia and plans movement (posture at start of movement and preparation of movement)
