Fig. 3.

Distributions of cortical eye dominance from eight control monkeys (A) and from the six amblyopic monkeys (B, C). Eye dominance is represented using the seven-point scale of Hubel and Wiesel (1962). For the control monkeys, group 1 represents dominance by the contralateral eye (C), and group 7 represents dominance by the ipsilateral eye (I). For the amblyopic monkeys, data collected from the two hemispheres are combined so that group 1 represents dominance by the treated eye (T) and group 7 represents dominance by the untreated eye (U). The tophistograms in B and C show distributions pooled across the three monkeys in each group; the bottom small histograms show the individuals’ data. Only neurons with receptive fields representing the central visual fields are included; 76 units recorded from the representation of the peripheral visual field in monkey FT are excluded. In monkey FP, 35 units recorded in V2 are included; these were statistically indistinguishable from 62 other units recorded in V1. All other recordings were from V1.
