Towards Wireless Brain Computer Interface: Light Activation of Neurons Via Nanoparticles

April 7, 2017February 24, 2009 by Brian Wang

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. …
