Figure 4.
A series of drawings of the ventral medulla of animal C48 showing the locations of RVLM neurons labeled by Fast Blue, Fluoro-Ruby, or both tracers. Drawings were constructed from montages of photomicrographs, which were used to determine the positions of labeled cells. The top section was located ~0.5 mm caudal to the rostral pole of the inferior olivary nucleus (IO); the sections below are spaced ~0.25 mm apart.
