The Role of Temporal Processing in Induced Presence Hallucinations
17.01.22Research
Led by Herberto Dhanis and Dr Eva Blondiaux this study on robotically-induced hallucinations has revealed novel insights into the neural mechanisms behind the induction of Presence Hallucinations, and Passivity experiences, by taking a closer look at the temporal relationships between distributed brain networks. Presence hallucinations are of major clinical importance and the most frequent hallucination in early Parkinson’s disease. As the authors explain in their article now published in NeuroImage, when a healthy person is sensitive to the induction of Presence Hallucination, the brain highly favours one brain network, having all other networks transition more to it over time. In contrast, if a healthy person is sensitive to Passivity Experiences, the brain will avoid one other specific brain network, having all brain network decrease the transitions to it over time. These data reveal specific temporal relationships of brain networks for a specific hallucination that is of relevance for the early detection of Parkinson’s disease.
