Recent studies of the postcentral and additional somatosensory cortice
s support a hierarchical scheme for information processing. In the pos
tcentral gyrus, the complexity of receptive field properties increases
with caudal progression from area 1. It has been reported that the an
terior bank of the intraparietal sulcus, the caudalmost part of the po
stcentral gyrus, is responsible for the systematic integration of bila
teral body parts, as well as of somatic and visual information.
