Predictions of adaptation effects for V1 and V2, if adaptation effects depend on sensitivity to texture statistics. A, Adapting to a texture and testing to a texture should produce strong adaptation effects in V1 (green) and V2 (blue). B, Adapting to a texture and testing to noise should elicit strong adaptation effects in V1 (green) but not V2 (light blue). C, Adaptation to noise and testing with a texture should produce strong adaptation effects in V1 (green) but not V2 (gray). D, Adapting with noise and testing with noise should produce strong adaptation effects in V1 (green) but not V2 (gray).
