Figure 4.

(A) Map of multijoint forelimb movements evoked with intracortical electrical stimulation from squirrel monkey case 08-03. Four retrograde tracers were injected: FB into M1/PM defense zone, FR into M1/PM reach zone, CTB into PPC reach zone, and DY into PPC defense zone. (B) Distributions of labeled cells in a series of coronal thalamic sections from the same case. A brief survival period limited tracer transport for at least 3 injections. The adequate number of labeled cells from tracer injection in the PPC reach zone was likely due to rapid CTB transport. Borders of thalamic nuclei were identified from architectonic analysis in adjacent sections.
