Predictive Processing
NeuroscienceA model of the brain as a prediction machine, constantly generating top-down expectations about incoming sensory data and updating them based on prediction error.
Example: Carhart-Harris and Friston's 2019 REBUS model ("RElaxed Beliefs Under pSychedelics") proposes that psychedelics work by loosening the precision, or felt confidence, the brain assigns to its own high-level predictions — letting bottom-up sensory and emotional information through unfiltered, theorized as the basis for why rigid depressive thought patterns can become revisable.
