Optogenetic Stimulation and Detection of Ca Waves (image) Technical University of Munich (TUM) Share Print E-Mail Caption A novel technique called optogenetics enables researchers to insert light-sensitive channels into specific types of neurons, shown green in this micrograph. Other neurons are shown in red. Through an optical fiber (right), scientists can use light both to stimulate these cells and to record their response.
