Abstract:
Light rather than electrical current: The inner or outer surfaces of glass micropipettes can be coated with nanoparticles of a narrow-band-gap semiconductor. When visible or near-infrared light is used for excitation, these micropipettes (labeled PE Stim in the image) can activate nearby neurons (labeled *) in brain tissue without the damage associated with electrical stimulation.
