Figure 6. Sections through the forebrain of a garter snake which underwent a stereotaxic lesion of 
A DVR. The brain was subsequently treated by a Fink-Heimer procedure. Section A is the most rostral. 
Cortical damage is not shown because other studies (Ulinski, 19766) indicated that cortex does not 
project to either ADVR or the striatum. The extent of the lesion is shown by the black area. Degenera- 
tion is shown by dots. Abbreviations: AC, anterior commissure; AOT, accessory olfactory tract; FB, 
forebrain bundles; IP intrapeduncular nucleus; LOT, lateral olfactory tract; MS, medial striatal nu- 
cleus; NS, nucleus sphericus; OC, optic chiasm; ON, optic nerve; OT, optic tract, PDVR, posterior 
dorsal ventricular ridge; S, septum.
