D: Camera lucida drawing
(63x) made from a region shown in box in (A), illustrating the
relationship of PHA-L labeled fibers/terminals and ChAT labeled neurons in the
sublenticular substantia innominata following a tracer injection in the lateral
hypothalamus (case L125). B,C: Micrographs of neurons in boxed areas in (D)
shown at higher magnification. Arrows
denote PHA-L labeled terminal varicosities in close apposition to cholinergic
neurons. Scale bar: 10 µm
