Abstract
Recent studies of the postcentral and additional somatosensory cortices support a
hierarchical scheme for information processing. In the postcentral gyrus, the complexity
of receptive field properties increases with caudal progression from area 1. It has
been reported that the anterior bank of the intraparietal sulcus, the caudalmost part
of the postcentral gyrus, is responsible for the systematic integration of bilateral
body parts, as well as of somatic and visual information.
