Correlation between gamma VSPF modulation range and psychological variables. a Scatter plots of correlation results for gamma VSPF and IQ in the ASD group. b Comparison of the oblique line discrimination thresholds in TD children and ASD children with (ASD+) and without (ASD−) marked reduction of gamma VSPF modulation range. Thresholds are given in the arbitrary units (a.u.) representing log-rescaled values of degrees of visual angle
