SYSTEMS, METHODS AND COMPOSITIONS FOR OPTICAL STIMULATION OF TARGET CELLS

摘要

PROBLEM TO BE SOLVED: To provide methods, systems and devices in connection with light-responsive ion channel molecules.SOLUTION: A method of activating a light-activated ion channel responsive to a light stimulus is implemented using a light-activated ion channel molecule responsive to a light stimulus. The method includes: engineering the light-activated ion channel molecule in a cell; and activating the ion channel molecule, in response to a light stimulus that is provided to the ion channel molecule and that does not have properties of activating a ChR2 ion channel, to allow ions to pass through the light-activated ion channel molecule.SELECTED DRAWING: None
