Human neuroimaging studies report that psychedelics induce serotonin-2A receptor-dependent changes in functional brain reorganization, presumably reflecting neuromodulation. However, these studies often overlook the potent vasoactive effects of serotonin. Here we identified psilocybin-induced alterations in hemodynamic response functions during human functional magnetic resonance imaging,...
