Design and Fabrication of Dual-Mode Neural Signal Detecting Instrument
摘要
Abstract
In order to meet the urgent need of neural signal detecting instrument in basic neuroscience research, dual-mode neural signal detecting instrument was developed. The detecting instrument is composed of central controlling module, electrophysiological module, electrochemical module, data acquisition module and neural signal analysis software, thus it can measure 128 channels of electrophysiological signals and 8 channels of electrochemical signals. 128 channels of weak electrophysiological signals from analog neural generator were obtained in electrophysiological module performance test, and the amplitude of the recorded neural spikes was 320μV. With 64-channel micro-electrode array, the different concentration of ascorbic acid solution was determined by using cyclic voltammetry in electrochemical experiment. The results indicate that the detecting instrument can measure electrophysiological and electrochemical signal, which would provide technical foundation for dual-mode neural information determination.关键词
