Using advanced computer models, neuroscience researchers have gained new knowledge about the complex processes that cause Parkinson's disease. Scanning the brain of a patient suffering from Parkinson's disease reveals that in spite of dopamine cell death, there are no signs of a lack of dopamine -- even at a comparatively late stage in the process.
