Figure 9.

The locations of electrophysiologically identified injection sites in areas 3a, 3b, 1, and 2 in cortex that was sectioned tangentially (top left box), and coronal sections of the thalamus (AF) in case no. 3. In the top left box the receptive fields for neurons at the center of each injection site are drawn on illustrations of the hand and color coded to match the area injected. Injections were centered in the representation of distal D4 in areas 3b and 1, and distal D3 and D4 in areas 3a and 2. Labeled cells resulting from injections in areas 1 and 2 were observed primarily in VPl, with moderate label in VPs. The injection in area 3a resulted in dense label in VLp and VPl. The injection in area 2 resulted in dense label in VPs and moderate label in VPl and VPi. In some instances double-labeled cells were observed in VPl and VPs from injections in areas 3b and 1 (grey boxes to the right). One double-labeled cell was observed in VPl from injections in areas 3b and 2. Solid lines in (AF) mark architectonic boundaries of thalamic nuclei, and dashed line mark approximate boundaries. Sections are shown in a caudal (A) through rostral (F) progression. These sections are spaced by 150 μm. Abbreviations in Table 1. Conventions as in previous figures.
