Figure 9.

The relationship between strength of disparity tuning (measured by the DDI) and the strength of modulation induced by the corrugations (measured by RM contrast). The filled symbols represent the neurons for which the RM was significant (n = 55), and open circles indicate the neurons for which RM was not significant (n = 26). All neurons included in this plot had significant disparity tuning (n = 81). There is a strong and significant (r = 0.5; p < 10 ^-5) correlation. All neurons with a DDI >0.65 showed significant RM. B, Frequency distribution for RM contrast values for the 81 cells tested. The open and filled bars represent nonsignificant and significant modulation, respectively.
