Chrmine opsin
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. WebAction potentials in ChRmine-expressing HVCMs can be triggered at ultra-low power (6 μW/mm2 at 10 ms pulse or 0.7 μW/mm2 at 100 ms pulse at 585 nm), which is 2-3 orders of magnitude lower than ...
