Comparison of responses and suppression as a function of contrast in five neurons that show a range of CRF contrast-response functions and suppression strengths from the eCRF. Each row represents a different neuron. The first column (A, D, G, J, M) shows contrast responses from the CRF for the example cells (mean ± 1 SD). Second (B, E, H, K, N) and third (C, F, I, L, O) columns show the percentage suppression as a function of contrast from collinear- and orthogonal-oriented stimuli in the eCRF, respectively (mean ± 1 SD). Lines are best fits of the Naka–Rushton function to the data. Collinear suppression was generally stronger than orthogonal suppression, and C₅₀s from eCRF were generally equal to or lower than C₅₀s from CRF.
