Changes in structural network topology correlate with severity of hallucinatory behavior in Parkinson's disease [PDF]

, 2019
Inefficient integration between bottom-up visual input and higher order visual processing regions is implicated in visual hallucinations in Parkinson's disease (PD). Here, we investigated white matter contributions to this perceptual imbalance hypothesis.

Subcortical Visual Hallucinations

Cortex, 1971
Summary The case material that has been reviewed suggests that lesions at all levels of the neurovisual system may be associated with visual hallucinations. Occurrence of the phenomenon of subcortical visual hallucinations is compatible with what is known about the complex integration of cortical and subcortical visual processes.
