Evidence That Primary Visual Cortex Is Required for Image, Orientation, and Motion Discrimination by Rats

Figure 3

Performance on visual tasks after V1 lesion.

Post-operative performance of subject S1, whose pre-operative performance is shown in Figure 2. Symbols and error bars as defined in Figure 2. In addition, motion discrimination was tested with 95% coherent motion (cyan) post-lesion. Performance fell to chance for motion discrimination tasks (cyan, green), image discrimination (blue) and orientation discrimination (black), yet was spared for the tasks requiring approaching a salient visual target (red, magenta).
