Unthresholded effects. Unthresholded average effects across the four conditions included in the first ANOVA (VS/LF, VS/HF, VNS/LF and VNS/HF). Top row displays mean beta estimates across participants for each of the two experimental groups. The bottom row displays unthresholded contrast maps showing regions were the groups' mean responses differ. Qualitatively these images suggest a high degree of similarity in activation patterns across KS and Controls with a few clear areas of difference, roughly corresponding to those that turn up as significant in the statistical tests.
