Remote control of behavior through genetically targeted photostimulation of neurons.
Optically gated ion channels were expressed in circumscribed groups of neurons in the Drosophila CNS so that broad illumination of flies evoked action potentials only in genetically designated target cells. Flies harboring the "phototriggers" in different sets of neurons responded to laser light with behaviors specific to the sites of phototrigger expression. Photostimulation of neurons in the giant fiber system elicited the characteristic escape behaviors of jumping, wing beating, and flight...Expand abstract
