Theories related to internal models, feedback control, and predictive coding also emphasize the importance of sensory prediction (and processing) before (and during) the movement itself, explaining why motor-related deficits can arise from damage to primary somatosensory cortex (S1). Similarly, it is asked, what happens if the primary sensory cortex is damaged? The secondary somatosensory cortex (SII; area 40) is in the lower parietal lobe. 5 C). What happens when the sensory cortex is damaged? There was no significant correlation between the somatosensory thickness and volume with the ASC-12/Brazil, migraine frequency, intensity, migraine onset or aura frequency. Primary somatosensory cortex (SI; areas 3,1,2) is located in the post central gyrus. The somatosensory cortex then reacts to the inputs in a complex association of processes by responding. The cortex, which is the outermost and latest development in the evolution of the vertebrate brain, is believed to be the central site of consciousness and intelligence, performing the most complex associative and mnemonic functions. Cerebral cortex damage can cause serious problems, depending on the location of the injury. Surgical removal of this region in one hemisphere results in a reduced ability on the opposite side of the body in the detection of light touch and some difficulty identifying objects by touch (stereognosis).
