Figure 4.
Regional and laminar contours with retrogradely labeled cells in prefrontal regions arising from tracer injections in PER and POR. A-C. Labeled cells from injection sites in PER area 36 shown at coronal level +3.2, +2.8, and +3.2 mm relative to bregma. D-F. Labeled cells from sites in area 35 shown at coronal levels +3.3, +3.2, and +2.8. G-I. Labeled cells arising from sites in POR shown at coronal levels +3.6, +3.6, and +2.8 mm. Scale bar = 250 μm. Panels B, D, E, G, and H are on the same scale as panel A. Other abbreviations: corpus callosum anterior forceps, fa; corpus callosum genu, ccg.
