Figure 6.
A, B, Counts (mean ± SEM) of PRV-only (white circles) and PRV-ir, DβH-ir (black squares) neurons throughout the VLM (from 11 to 15 mm caudal to bregma) at intermediate (A; n = 2) and late infection times (B; n = 3). Note the progression of infection: at the intermediate infection time, very few catecholaminergic neurons are infected with PRV in the caudal VLM (∼12.75–13.5 mm caudal to bregma), whereas at the late infection time, many catecholaminergic neurons of this region begin to become infected with PRV.
