Abstract
In pioneering studies on macaque monkeys, Marshall, Woolsey and Bard (1937) defined a region of postcentral parietal cortex that was responsive to stimulation of the body. The responsive region, which became known as the primary or first somatosensory region, S-I, contains four generally recognized architectonic fields, Areas 3a, 3b, 1, and 2. Since the original report of Marshall et al. (1937), there have been a number of interpretations of the significance of these four fields, and of the organization of the S-I region of primates (for recent examples, see Carlson et al., 1982; McKenna et al., 1982; Jones et al., 1978; Paul et al., 1972). In a series of papers, stemming from our first report on the organization of the S-I region in owl monkeys (Merzenich et al., 1978), my colleagues and I have argued that each of the four architectonic fields constitutes a functionally distinct area of somatosensory cortex.
