(a) Response maps of a CORF model cell without inhibition (, ), to gratings of different spatial frequency and orientation, (b) with moderate push-pull inhibition (, ) and (c) with strong inhibition (, ) The red and green plots indicate the marginal (MARG) row- and column-wise sums, and singular value decomposition (SVD), respectively. These results are comparable to the response of biological cells (see Fig. 3 in [51]).
