Expression vector comprising a nucleotide sequence encoding a Volvox carteri light-activated ion channel protein (VChR1) and implantable device thereof

Abstract

Methods, systems and devices are implemented in connection with light-responsive ion channel molecules. One such method is implemented using a light-activated ion channel molecule that responds 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 light stimulus that is provided to the ion channel molecule and that has properties that do not activate a ChR2 ion channel, to allow ions to pass through the light-activated ion channel molecule.
