Implant-free optogenetics minimizes brain damage during neuronal stimulation

A minimally invasive optogenetic technique that does not require brain implants successfully manipulated the activity of neurons in mice and monkeys, researchers report. The researchers first genetically engineered neurons to produce a newly developed, extremely light-sensitive protein called SOUL. They then demonstrated that it is possible to shine light through the skull to alter neuronal responses throughout the entire mouse brain, and to reach superficial regions of the macaque brain.
