Figure 4.

Examples of orientation tuning functions (A) and spatial frequency tuning functions (B) of a V2 neuron from a severely amblyopic monkey. Orientation bandwidth (half-width at half height) was 10.9 degree for the fellow eye and 24.5 degree for the amblyopic eye while orientation bias was 0.76 for the fellow eye and 0.46 for the affected eye. The optimal spatial frequency was 6.0 c/d for the fellow eye and 3.7 c/d for the amblyopic eye while spatial resolution for the fellow eye was 14.6 c/d and 10.2 c/d for the affected eye.
