News, events & podcast Volunteers with Charles Bonnet Syndrome wanted for brain scanning study Neurochemistry and Connectivity in the Brain in Charles Bonnet Syndrome Chief Investigator, Dr Jasleen K Jolly is looking for people who have reduced vision aged 18-70 years to understand how the brain can generate hallucinations linked to eye disease. Hallucinations are perceiving things or people that are not actually there. Dr Jolly needs people with reduced vision who experience visual hallucinations and also people with reduced vision who have never experienced visual hallucinations. Participants would be asked to answer some questionnaires and undertake a non-invasive brain scan (MRI). This research study hopes to understand the changes in the visual part of the brain that cause hallucinations to occur to help guide us in treating these. Participation would involve a single visit to the Wellcome Centre for Integrative Neuroimaging, FMRIB based at the John Radcliffe Hospital in Oxford. The visit will take up to 2 hours. They can only accept NHS registered UK residents. Travel expenses will be covered. For more information about this study, or to volunteer for this study please email the research team.
