D: Camera lucida drawing
(63X) made from region shown in box in (A) illustrating the relationship
of PHA-L labeled fibers/terminals and ChAT labeled neurons in the medial
portion of the HDB following tracer delivery to the anterior hypothalamic area (case M067). B,C: Micrographs of neurons in boxed
areas in (D) shown at higher magnification. Arrows denote PHA-L labeled terminal varicosities adjacent to
cholinergic neuronal elements. Scale bar: 10 µm.
