a, representative image of iontophoretic injection in DLM.
b, injection site mapped onto borders of DLM and
DTCbN as in Figs. 10 and
11, showing that it injection was
confined to DLM. c–e, series of consecutive sections
showing label from injection throughout Area X and in LMAN
f–j, Axon segments dotted with
varicosities as well as locally-ramifying axon-terminal like morphologies in
Area X. Each panel is a confocal image of the area(s) surrounded by a white box
in the panel above it. Ov, nucleus ovoidalis, PC, posterior commissure. Scale
bars: a, c–e 500 μm.
f–h, 50 μm. j, 100
