PROBLEM TO BE SOLVED: To provide a nerve signal probe capable of safe nerve stimulation and nerve activity measurement, in addition to a high selectivity of nerve fibers, and also provide a nerve signal output device, nerve signal recorder, nerve stimulator and nerve signal input/output device using the nerve signal probe.SOLUTION: The nerve signal probe is provided with a baseboard 13 integrating semiconductor integrated circuits (signal selection circuit) 26, a pedestal layer 11 installed on the surface of the baseboard 13 and having a plurality of implanting through holes and a probe array of metal needles Pij-1, Pij, Pij+1, Pij+2, and so on, each of which has the lower part implanted into each through hole and covered with an insulating film except its tip and bottom. The probe array is used at least in part to transform the nerve activity signal into an electric signal and electrically stimulate nerves.COPYRIGHT: (C)2008,JPO&INPIT【課題】神経線維高選択性に神経刺激や神経活動測定ができると共に、これを安全に行える可能な神経信号用プローバ、並びにこの神経信号用プローバを用いた神経信号出力装置、神経信号記録装置、神経刺激装置及び神経信号入出力装置を提供する。【解決手段】半導体集積回路(信号選択回路)26を集積化した基板13と、基板13の上面側に設けられ、複数の植込用貫通孔を有する台座層11と、複数の植込用貫通孔のそれぞれに下部を埋め込んで固定され、先端部と底部を除き絶縁被膜で被覆された金属鍼pij-1,pij,pij+1,pij+2,……からなるプローブアレイとを備え、プローブアレイの少なくとも一部により、神経活動信号を電気信号に変換し、且つ神経を電気的に刺激する。【選択図】図2
