The Predictive Coding Account of Psychosis.
Biol Psychiatry May 25, 2018 Peer reviewed DOI: 10.1016/j.biopsych.2018.05.015 via PubMed Central
Summary
The predictive coding framework explains psychosis as a disruption in the brain's normal process of generating predictions about sensory input and updating them based on new evidence. In this account, psychotic symptoms such as hallucinations and delusions arise when the brain gives too little weight to sensory evidence or too much weight to prior expectations, leading to faulty perceptions and beliefs. The theory integrates findings from neuroscience and computational psychiatry.
