Single neurons were recorded in owl monkey middle temporal visual cortex (MT). Directional neurons showed direction-selective adaptation to pattern motion: responses to motion in the preferred direction were reduced by adaptation to motion in the preferred direction and enhanced by adaptation in the opposite direction. Non-directional neurons did not show significant adaptation.
