NettetThis means that the primary cortex in the right cerebral hemisphere represents motor activity on the left side of the body and vice-versa. It is important to recognize that the density of receptors for various parts of the body are not the same which is why the homunculus represents different sizes as it extends over the cortex. NettetSensory cortex refers to all cortical areas associated with sensory function. In the case of vision, this includes virtually all of the occipital cortex and much of the temporal and parietal cortex. An object must be perceived before it can be categorized, so an intact sensory cortex is necessary for normal categorization.
