WebThe output of the unimodal cortices is, in large part (though not exclusively) to the heteromodal areas. In broad terms, the unimodal cortices are thought to be responsible for decoding (analyzing) and/or re-encoding (synthesizing) the sensory input received from their respective primary cortices. This process is thought to result in the more ... WebThe primary somatosensory cortex is located in a ridge of cortex called the postcentral gyrus, which is found in the parietal lobe.

WebAreas of the cerebral cortex that receive the first signals from sensory receptors are called primary sensory areas. These areas are separate for each sensory modality, but the major primary sensory regions are those for vision, hearing, and sensation.

WebSomatic sensory information is distributed from the primary somatic sensory cortex to “higher-order” cortical fields (as well as to subcortical structures). One of these higher-order cortical centers, the secondary somatosensory cortex (sometimes called SII and adjacent to the primary cortex; see Figure 9.7), receives convergent projections from the primary … proi ts center scheduWebprimary visual cortex (V1), it improves the stimulus representation in this area, as revealed by MVPA.
