Figure 7.

(A) Map of multijoint forelimb movements evoked with intracortical electrical stimulation from owl monkey case 07-103. Four retrograde tracers were injected: FR into the M1/PM defense zone, DY into M1/PM near sites that evoked grasping and mouth opening, CTB into PPC reach zone, and FB into PPC defense zone. (B) Distributions of labeled cells in a series of coronal thalamic sections from the same case. A limited number of cells were labeled from the M1/PM defense zone injection likely because of a small injection volume of FR.
