Neuroscientists have developed a powerful new class of tools to reversibly shut down brain activity using different colors of light. When targeted to specific neurons, they could potentially lead to new treatments for abnormal brain activity associated with disorders including chronic pain, epilepsy, brain injury and Parkinson’s disease.
Such disorders could best be treated by silencing, rather than stimulating abnormal brain activity. These new tools, or ‘super silencers,’ exert exquisite control over the timing in which overactive neural circuits are shut down—an effect that is not possible with existing drugs or other conventional therapies.
“Silencing different sets of neurons with different colors of light allows us to understand how they work together to implement brain functions,” explains Ed Boyden, senior author of the study. “Using these new tools, we can look at two neural pathways and study how they compute together,” he says.
