Relaxed belief

This paper formulates the action of psychedelics by integrating the free-energy principle and entropic brain hypothesis. We call this formulation relaxed beliefs under psychedelics (REBUS) and the anarchic brain, founded on the principle that-via their entropic effect on spontaneous cortical activity-psychedelics work to relax the precision of high-level priors or beliefs, thereby liberating bottom-up information flow, particularly via intrinsic sources such as the limbic system.REBUS and the Anarchic Brain: Toward a Unified Model of the Brain Action of PsychedelicsR L Carhart-Harris , K J Friston. 2019 Jul;71(3):316-344.  doi: 10.1124/pr.118.017160.
