Averaged normalized activity of 105 neurons to offset of an optimally oriented bar with and without background offset. Rebound activity was found with background offset (black curve) but not when the background was static gray (gray curve). Prior to the beginning of the rebound activity, the response with the background offset appeared suppressed compared to the response without background offset. This data set of 105 neurons was collected when fixation was only required for 500 ms after stimulus offset.
