Abstract
The first somatic sensory area (SI) of higher primates occupies the postcentral gyrus and is a composite of four distinct architectonic areas (areas 3a, 3b, 1 and 2). Each of these probably contains a separate map of the contralateral half body, although information on this subject is primarily derived from studies of areas 3b and 1 (Nelson et al, 1980). Most recent anatomical and physiological studies of SI have been concerned with the differential processing of sensory information by areas 3a, 3b, 1 and 2 and their place in the circuitry leading to the motor cortex or to the higher sensory perceptive areas putatively located in the parietal lobe (Jones et al, 1978 Sur et al, 1981; Jones 1986). Rather less attention has been devoted to the individual nerve cells of the SI cortex and to their roles in intrinsic cortical circuitry, particularly that supervening upon the arrival of an afferent volley and leading to the emergence of a cortical output. In what follows, I shall attempt to deal with certain aspects of this neglected issue and to arrive at a tentative circuit diagram of the intrinsic circuitry of the SI cortex.
