Figure 6. Response gain control elicited by contrast and speed adaptation.

Scatter plots showing response-shift induced by speed adaptation (ordinate) as a function of response-shift induced by contrast adaptation (abscissa) following low (A) and high (B) speed adaptation. Points to the left of the vertical line and below the horizontal line show a decrease in maximum firing rate following adaptation (response gain). Response gain is present in almost all cells following adaptation at either speed when using either the contrast tuning protocol or the speed tuning protocol.
