Optogenetic Control of Mammalian Ion Channels with Chemical Photoswitches.

Abstract excerpt

In neurons, ligand-gated ion channels decode the chemical signal of neurotransmitters into an electric response, resulting in a transient excitation or inhibition. Neurotransmitters act on multiple receptor types and subtypes, with spatially and temporally precise patterns. Hence, understanding the neural function of a given receptor requires methods for its targeted, rapid activation/inactivation in defined...
