Abstract

Receptive fields were determined for recording sites in cortical areas 1, 2 and 5 in macaque monkeys. While a mixture of cutaneous and deep receptors were represented in most regions of area 2, a specific mediolateral level of area 2 was highly responsive to cutaneous input. Anteroposterior rows of recording sites across areas 1, 2 and 5 at this mediolateral location revealed a continuous sequence of cutaneous receptive fields proceeding from the occiput and face in area 1 to the forearm and hand in area 5.

    The somatotopy of tactile maps in all four anterior parietal areas is known in detail, primarily from extracellular unit recordings in anesthetized monkeys. These studies mapped receptive fields using near-threshold indentation of the skin with hand-held probes, in both macaques (Nelson et al., 1980; Pons et al., 1985a, b, 1987b; Rothemund et al., 2002; Krubitzer et al., 2004) and New World monkeys (Merzenich et al., 1978; Kaas et al., 1979; Sur et al., 1980, 1982; Felleman et al., 1983; Carlson et al., 1986; Cusick et al., 1989). Three major features of somatotopic maps are evident (Figs 4.1B and 4.2A), consistent with Penfield and Woolsey's early recordings.

    Case SM-Ge (Fig. 7) had foci for the 3 digits in expected locations for area 3b, but foci for only digits 2 and 3 in area 3a, and digits 1 and 2 in area 1. Additional foci were detected caudomedially in area 2 or perhaps area 5, where more convergence of inputs from digits is expected (Cooke et al., 2014; Padberg et al., 2009; Padberg et al., 2010; Pons et al., 1985). The somatotopy and area boundaries defined by fMRI were consistent with the known areal and somatotopic organization, and inter-session co-registration of functional images can be as accurate as ~ 140 μm (Lecoeur et al., 2011b).

    However, so far, no direct evidence has been provided regarding whether gyral and sulcal parts of the M1 pyramidal neurons have different roles regarding the load effect. In the primary sensory cortex (S1), which is deeply associated with movement, it has been proved that there is a difference in distribution: area 3b in the cerebral sulcus is highly responsive to cutaneous input, while area 3a in the depth of the cerebral sulcus and areas 1 and 2 in the cerebral gyrus are the main areas for receiving afferent impulses from the muscle and/or joint (Phillips et al., 1971; Heath et al., 1976; Cusick et al., 1985; Pons et al., 1985, 1992; Tremblay et al., 1996; Burton et al., 1997). Sensory receptor input is represented in S1 and even in M1.
