Provided is a neural probe array including a probe which is insertable into a nerve, the probe having a microchannel which induces the regeneration of the nerve, wherein an electrode is installed within the microchannel and is physically isolated from gliosis, and the microchannel is configured to receive a nerve growth factor for regenerating the nerve, and when the probe is inserted into the nerve, the electrode physically isolated from gliosis accomplishes neural signal acquisition and stimulation.
