Fig. 7.

Receptive fields of neurons in two penetrations through the posterior bank of the central sulcus in monkey MCh75. The penetrations illustrated here correspond to those marked by the black and the open arrowheads in Fig. 4 and use the same color codes. The receptive fields of neurons at the sites marked by letters are shown on the figurines on the left. Note that at many sites the receptive fields split with responses elicited by touch on the hand/arm as well as chin. The receptive fields on the hand are large, often extending over multiple digits, unlike those in normal animals. For other conventions see legend to figure 4A.
