Horizontally elongated inhibitory end zones need not alter the orientation tuning. (A) Receptive field and inhibitory end zones. The gray scale shows the receptive field—a Gabor function in which a central ON region (white) is flanked by two OFF regions (black). The contours show the ten inhibitory end zones. Each inhibitory zone is a gaussian, and the contour marks the half-maximum. (B) Orientation tuning curve for the model with (dashed line) and without (solid line) gating by the inhibitory zones. This demonstrates that the horizontally elongated inhibitory zones do not alter the orientation tuning of the cell: it still responds best to a grating oriented at 45 degrees.
