title: Visual activity in the telencephalon of the painted turtle, Chrysemys picta.
abstract: Multiple unit activity in response to visual stimulation was recorded in the following telencephalic areas of the painted turtle: lateral and medial divisions of the dorsal cortex, lateral and medial divisions of the dorsal ventricular ridge, and the striatum. The data confirm anatomical evidence for ascending visual input to the dorsal cortex, the lateral dorsal ventricular ridge and the striatum. The identification of a new visual zone in a medial division of the dorsal ventricular ridge suggests that turtles, and perhaps other reptiles, possess at least 3 visual pallial areas.
