How Psychedelics Influence Brain Networks

Psychedelics can produce mystical experiences, and higher scores on the Mystical Experience Questionnaire are linked to stronger therapeutic benefits such as reduced cravings and anxiety. These substances disrupt the default mode network, a brain system involved in psychiatric disorders and the sense of self, which may lessen negative self-referential thinking. Psychedelics may also disrupt the claustrum, creating a dynamic brain state that, within a therapeutic setting, could help shift deeply ingrained negative thoughts.

Abstract

Psychedelics can induce mystical experiences, with higher Mystical Experience Questionnaire scores correlating with greater therapeutic effects like reduced cravings and anxiety. Psychedelics disrupt the default mode network, which is implicated in psychiatric conditions and sense of self, potentially reducing negative self-referential thinking. Psychedelics may disrupt the claustrum, inducing a dynamic brain state that, in a therapeutic context, could help shift deeply held negative thoughts.
