Imaging voltage with microbial rhodopsins

Witryna(22) suggest that large-area 2P voltage imaging in intact tissue will be technically difficult with any GEVI. We explored whether the complex photocycles of microbial rho-dopsins could open the door to nontraditional optically sectioned voltage imaging techniques. Microbial rhodopsins have multiple WitrynaLight is one of the most useful resources for the transmission of energy and information, and most living organisms can capture light using rhodopsins. Rhodopsins are classified into two groups, microbial and animal. Both are characterized by a seven-transmembrane domain that binds a small chromophore (retinal), but their functions …
