Optogenetics — the might of light

WebApr 1, 2024 · In the 1980s, Nobel laureate Francis Crick suggested that light might have the right stuff for controlling neurons of different types, thanks to its ability to provide timed pulses with millisecond temporal precision. However, light penetrates only a few hundred microns into the surface of the brain, scattering without affecting signaling. Weboptogenetics, experimental method in biological research involving the combination of optics and genetics in technologies that are designed to control (by eliciting or inhibiting) well-defined events in cells of living animal tissue. Unlike previously developed experimental methods of light control, optogenetics allows researchers to use light to turn cells on or …
