Effects of the duration of brief daily periods of unrestricted vision on binocular signal interactions in V2 neurons. (A) Representative binocular disparity sensitivity functions of a V2 neuron from a monkey reared with continuous form deprivation (left), a monocularly form deprived monkey with 2 hours of unrestricted vision (middle), and a normal monkey (right). BII, binocular interaction index. Dotted line with an open triangle indicates the response level of the dominant eye. Open triangle at the bottom right indicates the response level of the nondominant eye. Open square: the noise level (spontaneous firing). (B) Average (±SE) BII values for each subject group. (C) Average (±SE) peak B/M values for each group. (D) Proportion of binocularly suppressive units (peak B/M < 0.0 dB).
