Figure 3.

Effects of the duration of brief daily periods of unrestricted vision on the orientation bias of V2 neurons. (A) Representative orientation-tuning functions for the affected eye from a monkey reared with continuous form deprivation (0 hours of unrestricted vision) (left), a deprived monkey with 2 hours of unrestricted vision (middle), and a normal monkey (right). (B) Interocular comparisons of the orientation biases of binocular units (ODI = 0.2–0.8; open circles). Filled symbols: mean values (±SE). Open squares on the x- and y-axes indicate comparable data for monocular units (ODI = 0.0–0.2 or 0.8–1.0). Filled symbols on the x- and y-axes show the mean values (±SE) for monocular units and filled symbols near the unity line indicate the mean values (±SE) for binocular units. If error bars are not visible, the standard errors are smaller than the size (length and width) of the symbols.
