WebNov 5, 2024 · Optogenetics involves microbial rhodopsins (opsins) as light-sensitive actuators of neurons. Upon exposure to light of the correct wavelength, the retinal chromophore bound to the opsin changes its chemical configuration, leading to a conformational change in the opsin structure. WebDec 28, 2024 · We sensitized RGCs with adeno-associated virus (AAV) delivery of red-shifted opsin, ChRmine, and systematically analyzed the ERG responses of RGCs to a series of differently colored optical situations. We discovered that high-frequency OPs are directly associated with RGC electrophysiological activity.
