Localization of cortical injection sites. The digit representations of M1, the PMd, and the PMv were mapped using intracortical stimulation. Then, we injected FB into one digit representation and DY into another digit representation. A, The dashed box on a cebus monkey brain delineates the region magnified in B-D. B, Animal R12 with injection sites in the PMd and M1. The injection site outlines indicate the extent of zones 1 and 2 (see Materials and Methods for additional details). The symbols indicate the movement evoked at each site and its threshold (large, <5 μA; medium, 5-10 μA; small, >10 μA). C, Animal R15 with injection sites in the PMv and M1. D, Animal R24 with injection sites in the PMd and PMv. ArS, Arcuate sulcus; CS, central sulcus; IPS, intraparietal sulcus; LS, lateral sulcus; PS, principal sulcus.
