Left column: (top) A network showing increased functional connectivity to happy vs. angry faces was observed in the gamma band in TD children. The glass brain is shown on top with node size scaled by degree. (middle) Plot of mean network strength for each participant by happy and angry emotion. (bottom) Strength of this network activation did not show significant correlations with TOCS. Right column: (top) For the OCD group, a significant network of increased connectivity to happy vs. angry faces was found in the beta band. Networks are represented in the glass brains with node size scaled by degree. (middle) The mean network connectivity strength for each child is plotted in the dot plots by emotion. (bottom) Mean connectivity strength for happy faces shows a significant negative correlation with TOCS (r = -0.37).
