다채널 실시간 신경신호 기록 및 처리 시스템의 개발

Abstract

In this paper, we describe a real-time multichannel system for acquisition and analysis of extracellular neural signal. This system enables real-time display and storage, detection and classification of the neural signal recorded with semiconductor multi-channel microelectrode array. The system consists of signal amplification and filtering part, transmission part, real-time acquisition and signal processing part including unsupervised and supervised neural spike sorting module.
