Figure 5

Schematic drawing of retrogradely labeled cells in the dorsomedial medulla at levels around the area postrema (AP) following cholera toxin B subunit (CTB) injections into discrete brain regions. (A) CTB injection sites (PBL, PB, PAG, PVH, ACe and BNST), which correspond to those at G, E, B and A levels in Figure 1B. (B) Drawings of retrogradely labeled cells (indicated by dots) following CTB injection into each brain region in a series of four transverse sections of the dorsomedial medulla (from rostral to caudal). Upper-right numbers indicate each distance in mm from the calamus scriptorius.
