A light-sensitive compound enables heatless membrane modulation in photoswitches

Optical technologies that can be used to modulate neuronal activity are opening up exciting possibilities for research in neuroscience and biology. Optical tools allow neuroscientists to excite and inhibit neurons or areas of the brain at will. They can thus be used to investigate the function of specific brain circuits or regions, as well as to identify new potential treatments for neurological and psychiatric diseases.
