Fig. 5 and 6.
Camera lucida drawings of
coronal forebrain sections, arranged from rostral (5A) to caudal (6B) to illustrate the distribution of PHA-L labeled
fibers in relation to cholinergic neurons following tracer deposit in the
far-lateral hypothalamus (case L125). The hatched area in the inset shows the
maximum extent of the region containing neurons labeled at the injection site. In these and the following
figures (Figs. 7-17) only the most proximal dendritic segments of cholinergic
neurons were drawn, and most of the dorsal and ventral striatal cholinergic
neurons have been omitted for simplicity. Sections were Nissl counterstained,
and adjacent sections immunostained for GAD for delineation of pallidal
borders.
