Abstract
In order to reduce the reactive tissue response around implanted neural electrodes for neural recording, carbon fiber-based microelectrode arrays are developed. Since the diameter of the carbon fiber (7 μm in diameter) is much smaller than the conventional micro-wires or the microfabricated silicon-based electrodes, it is expected that the carbon fiber neural probe is appropriate for the long-term neural recording. We introduce the multi-channel microelectrode array, each channel of which is composed of multiple carbon fiber bundles and show the preliminary neural responses recorded in motor cortex of anesthetized rat. While each carbon fiber is too flexible to be inserted in the rat brain, the bundle of carbon fibers can sustain each other to insert the electrode into the brain.
