Mind-wandering in Parkinson’s disease hallucinations reflects primary visual and default network coupling

Ishan C. Walpola, Alana J. Muller, Julie M. Hall, Jessica R. Andrews‐Hanna, Muireann Irish, Simon J.G. Lewis, James M. Shine, Claire O’Callaghan

This study finds that Parkinson’s disease patients with visual hallucinations show increased mind-wandering and stronger coupling between the primary visual cortex and default network.

Changes in structural network topology correlate with severity of hallucinatory behaviour in Parkinson’s disease

Julie M. Hall, Claire O’Callaghan, Alana J. Muller, Kaylena A. Ehgoetz Martens, Joseph R. Phillips, Ahmed A. Moustafa, Simon J.G. Lewis, James M. Shine

The paper investigates how structural network topology changes correlate with hallucinatory behavior severity in Parkinson’s disease using graph theory and connectivity analysis.

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

Claire O’Callaghan, Julie M. Hall, Alessandro Tomassini, Alana J. Muller, Ishan C. Walpola, Ahmed A. Moustafa, James M. Shine, 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.
