Researchers working in the lab of Carnegie Mellon University neuroscientist Aryn Gittis have identified two groups of neurons that can be turned on and off to alleviate the movement-related symptoms of Parkinson’s disease. The activation of these cells in the basal ganglia relieves symptoms much longer than current therapies, like deep brain stimulation and pharmaceuticals.

The study, completed in a mouse model of Parkinson’s, used optogenetics to better understand the neural circuitry involved in Parkinson’s disease, and could provide the basis for new experimental treatment protocols. The findings, published by researchers from Carnegie Mellon, the University of Pittsburgh and the joint CMU/Pitt Center for the Neural Basis of Cognition (CNBC) are available as an Advance Online Publication on Nature Neuroscience’s website.
