Figure 8. The influence of CRF scatter on orientation tuning and contextual modulation.
(a) The medians of OSI, HWHH, CMI, the strength of iso-orientation suppression and the strength of cross-orientation facilitation are plotted against the standard deviation of CRF center displacement σ. Dotted line indicates the σ that corresponds to the CRF size. (b) Profiles of a hypothetical distribution of various degrees of CRF center displacement.
