Two stage Wilson neural network model. (A) The first stage comprises monocular left and right neurons selective to orthogonal gratings. Reciprocal inhibition between different eyes and grating orientations are represented by heavy lines with filled circles at the ends. The second stage represents binocular neurons in higher cortical layers that receive the summation of left and right monocular neurons with the same grating orientation [2]. The isolated units at the first stage that we analyse are marked with the dashed box. (B) Horizontal (H) and vertical (V) stimuli swapped between the left (L) and the right (R) eyes (no flicker). At a specific time, one eye receives horizontal stimuli and the other receives vertical stimuli, each stimulates their own corresponding population at the first stage
