Evidence That Primary Visual Cortex Is Required for Image, Orientation, and Motion Discrimination by Rats
Symbol colors and error bars as defined in Figure 2. A. Task acquisition. This subject had learned an Approach Visual Target task previously (not shown). B. Stability of performance on visual tasks immediately after acquisition and before surgery. C. Post-operative performance after medial extrastriate lesion. No behavioral deficits were observed for approaching salient visual targets (red, magenta), image discrimination (blue), random dot motion discrimination (green), or orientation discrimination (black).
