Group analysis of the power at delta and alpha bands. Red indicates higher power for ASD and blue for TD. Power differences were observed only in frontal delta and posterior alpha bands at specific sensors. The top panel shows all the sensors that demonstrate a power difference trend (p < 0.4), with group differences in these areas similar to the source group findings reported in Cornew et al. (2012). The bottom panel shows sensors with significant (p < 0.05) group difference. The affected sensors in the bottom panel were not included in the regions revealed by max-MSE (in Fig. 3), indicating that group MSE differences are not related to group power differences
