Following a fascinating talk Aryn gave at OptoDBS 2022, we talk about her work on optogenetically inspired deep brain stimulation for Parkinson's Disease. In a first paper (2017 Nature Neuroscience), Aryn's lab could establish that a specific lineage of cells in the external pallidum needed to be stimulated (or a second one suppressed) to achieve symptom relief in the 6-OHDA mouse model of Parkinson's Disease. Crucially, these effects outlasted the stimulation, sometimes by up to eight hours. In...
