This study uses high-resolution fMRI to show that SN/VTA and LC activity differ in their response to rewarded versus visually salient stimuli, indicating distinct roles in reward and salience processing.

This study uses fMRI to investigate how the locus coeruleus and SN/VTA contribute to reward and valence processing in humans, finding distinct and joint roles in response to reward and negative valence.

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.

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

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.
