Figure 3.

Photomicrographs of retrogradely labeled cells in the hemisphere ipsilateral to the injection of neuronal tracer. Photomicrographs of retrogradely labeled cells with (a) FR, (b) FE, (c) FB, and (d) BDA in the ipsilateral hemisphere. Only cell bodies displaying a fully round soma and a minimum of 2 protuberances (considered being either dendrites and/or axon) were considered labeled neurons. A marker was overlaid onto the cell in Neurolucida (Microbright-Field, Inc.) in the reconstruction of the section. Brightness and contrast were adjusted. Scale bars = 100 µm.
