1. Surround integration and suppression in the direction domain.
Surround integration and suppression in the direction domain. A, Surround suppression occurs in direction space at high contrast, but not at low contrast for an example neuron. B, Contrast response function for the same example neuron using 100% coherent dots in the preferred direction. The line indicates the Naka–Rushton function fit. C, Population data for direction surround integration. Scatter plot of the IID at low contrast against the IID at high contrast (rank sum test, p < 0.001). The marginal distributions are histograms of the IID (median at high contrast = 0.002; median at low contrast = 0.084). Dashed lines in the histograms show location of IID = 0.
