Divisive inhibition can cause overestimation of support. a, In this model RF, the maximum spectral extents of the regions of inhibition (dashed red line) and excitation (solid blue line) were identical, although the profiles had different shapes; in the temporal dimension, both extents and profile shapes were the same. b, Inhibitory sidebands are clearly apparent when an STRF is estimated using the DRC stimulus c. In the STRF estimated with the ensemble of ripples, an alternating pattern extends beyond the simple sidebands and outside the support of the model.
