표면플라즈몬공명(SPR)현상을 이용한 좌골신경신호의 광학적 측정

Abstract

The SPR can directly detect electrochemical signals at the metal-electrolyte interface. In addition, this method has no time limit and no stimulation artifact. A new optical recording system was developed for detecting neural signal using surface plasmon resonance (SPR). Experimentally, evoked compound action potentials from rat sciatic nerves were successfully recorded. These results show that the SPR system can be used as a valuable tool for neural network research.
