Fig. 10.     Comparison of the distribution of putative interaction sites between DBH-positive terminals and cholinergic neurons (A) and those between BFC neurons and axon terminals originating in the locus coeruleus (B). These maps were composed from six camera lucida drawings (similar to that in Fig. 4 or Fig. 7 inset), which were aligned and superimposed to generate the final figure. Cholinergic cell bodies are represented by black dots. Zones of putative contacts between cholinergic elements and DBH or PHA-L-labeled terminals are depicted as red squares (corresponding 80 × 80 µm areas in the section).
