Statistic tests (p<0.05) carried out on the time-frequency representation of current dipoles in the 3 ROIs analyzed for the auditory versus visual condition. t-test over time-frequency bins of 11 subjects (10 degrees of freedom). Time frequency analysis was done over activity localized on the cortex in b) IFG, d) RSTG and f) LSTG as well as over channel level activity in a) F7, c) T8 and e) T7. In red: bins whose statistics are greater than the null hypothesis of zero mean. In blue: bins whose statistics are smaller than the null hypothesis of zero mean.
