Abstract

We fabricated carbon-nanotube-coated electrodes usable for intracortical microstimulation in vivo. The stimulus-induced cortical responses visualized by the voltage-sensitive dye imaging exhibited spatio-temporal patterns of the neural excitations comparable to those induced via metal-surface stimulating electrodes. This suggested a feasibility of stimulating electrodes with the carbon-nanotube interface.
