Accumulation of sensory evidence is impaired in Parkinson’s disease with visual hallucinations

Claire O’Callaghan, Julie M. Hall, Alessandro Tomassini…·Simon J.G. Lewis

This study uses a hierarchical drift diffusion model to show that Parkinson’s disease patients with visual hallucinations have slower sensory evidence accumulation, suggesting impaired bottom-up processing and increased reliance on top-down influences.
