Abstract
Optokinetic performance was measured in two groups of red-eared turtles; next, one group received bilateral ablation of the general cortex and the other received bilateral ablation of the optic tectum. After recovery, optokinetic performance was measured again. Cortical ablation had no effect, whereas tectal ablation brought about a deficit in responding in a 19-stripe, but not in a 4-stripe drum. These results support the traditional view that the optic tectum is a major visual center in reptiles.
