Neurobiology of Fear #3 Three types of optogenetic transgenes Channelrhodopsin is a sodium channel sensitive to blue light, which causes sodium to enter and depolarize the cell. (excites cell) Halorhodopsin is a chloride pump sensitive to yellow light, which causes chloride to be pumped in, hyperpolarizing the cell.
