Evidence That Primary Visual Cortex Is Required for Image, Orientation, and Motion Discrimination by Rats
Each symbol shows the fraction of correct responses for one task at the end of one day. Color indicates task as follows: Approach Salient Visual Target (Figure 1A) with statue target (red) or CW grating target (magenta); Image Discrimination (Figure 1B) (blue); Motion Discrimination (Figure 1C) with 85% coherent motion (green); and Orientation Discrimination (Figure 1D). Error bars indicate the 95% binomial confidence bounds. Training day indicates calendar days, except that a three week gap in training occurred after day 10 (slash marks). Performance is only reported when the rat's side bias was <15% and ≤40 valid trials completed on a given day; training occurred on other days and tasks not meeting these criteria.
