MAX-like responses in complex cells. A, A complex cell ON–ON matrix and ON–OFF matrix filled as described in Figure 2. All of the paired responses are clearly sublinear, and the example magnified traces show that the paired responses are very similar to the maximum of the individual responses, indicating MAX-like behavior. B, OFF–OFF and OFF–ON matrices for a second complex cell, both demonstrating mostly MAX-like responses independent of bar distance or polarity.
