Abstract

Carbon nanotubes vertically aligned to the surface of microtransducers such as metal microelectrodes or FET-based devices are proposed as electrical interfaces to neurons. A model of such a system is developed to simulate the induced extracellular neuronal electrical activity. The results brought out nanotubes act on the amplitude and the shape of the extracellularly recorded signals and promote an increase in the efficacy of neuronal signal transmission.
