Monocular and Binocular Mechanisms of Contrast Gain Control

  title={Monocular and Binocular Mechanisms of Contrast Gain Control},
  author={Izumi Ohzawa and Ralph D. Freeman},
Prolonged stimulation by temporally modulated sinusoidal gratings causes a decrease in the contrast sensitivity and response of neurons in the visual cortex. We have studied the dynamic aspects of this contrast gain control mechanism, and how its temporal properties affect the determination of neural contrast response functions. In addition, we have considered the possibility that a single mechanism is sufficient to explain monocular and binocular properties of contrast gain control. We find… CONTINUE READING
