The Lacertilian Forebrain

Figure 2. Chartings of anterograde degeneration seen in the telencephalon of Gekko following a lesion which 
involved the dorsal cortex, part of the medial wall, and the dorsal ventricular ridge. Degenerated fibers of 
passage are represented by dashes and terminal dereneration by stippling. The lesion is represented by 
the shaded regions on the left sides of each drawing. Most degenerated fibers cross in the hippocampal 
commissure to terminate densely in the contralateral septum (S), medial cortex MC, dorsomedial cortex 
(DMC), and dorsal cortex (DCm, DCl, and CP). Sparse terminal degeneration is present in the lateral 
edge of the DVR and striatal area contralaterally. Whereas ipsilaterally degeneration superficial to the cell 
plate of medial cortex (MC) forms three bands of different densities, contralaterally only the deepest of 
these bands contains degeneration. Only an occasional degenerated fiber was seen in the anterior com- 
missure following this lesion. Modified Eager method. Survival time 16 days. See Fig. 1 for abbreviations.
