Figure 8.

Fluorescent photomicrographs of horizontal sections through the rostral NTS containing DiI-labeled chorda tympani terminal fields in a control rat (A–C) and in a 90 days post-CTX rat (D–F). The dorsal-ventral levels are the same as shown in Figure 3; A,D represent zone C in Figure 5; B,E represent zone D in Figure 5; C,F represent zone E in Figure 5. The approximate location of NTS is outlined in white. The size and shape of the label are similar between groups. Rostral (R) and lateral (L) are indicated in A. Scale bar = 200 μm.
