fMRI results The mixed ANCOVAs calculated for the subregions of the ACC showed the following results: Spontaneous brain activity in the sgACC showed a significant effect of time ( F (2, 132) = 14.21, p < 0.001, η p 2 = 0.18), a marginally significant interaction effect between time and group ( F (4, 132) = 2.12, p = 0.084, η p 2 = 0.06), and no main effect of group.
