Preller, Erich Seifritz, Franz X. Vollenweider NeuroImage : Clinical, 2016, 11, 53–60 http://dx.doi.org/10.1016/j.nicl.2015.08.009 a b s t r a c t Stimulation of serotonergic neurotransmission by psilocybin has been shown to shift emotional biases away from negative towards positive stimuli. We have recently shown that reduced amygdala activity during threat processing might underlie psilocybin's effect on emotional processing. However, it is still not known whether psilocybin modulates bottom-up or top-down connectivity within the visual-limbic-prefrontal network underlying threat processing.We therefore analyzed our previous fMRI data using [...]
