Abstract

The invention is a kind synchronous recording system for experience animal behavior and electrophysiology signal, which belongs to nerve biology experience device. The recording system includes a video gathering card, a camera, an aD sampling board, an electrophysiology signal amplifier, micro electrode, a computer which stores the video and electrophysiology signal gathering procedure in the memory. The invention stores the video and electrophysiology data through programming correspondent procedure, it corresponds the electrophysiology signal and the animal behavior and maintain the synchronization in the playback process. The gathering of video and the electrophysiology signal are integrated together. It provides several kinds of video compressing methods; it has multi-channel, multi-frequency electrophysiology data sampling rate and video sampling rate of 1-30 frames / second; provides video finding mode step-by-step; it can output the synchronization of electrophysiology data and the animal behavior in a high accurate time range.

Description

Technical field: [0001] The invention relates to a synchronous recording system of experimental animal behavior and electrophysiological signals, which belongs to neurobiology experimental devices. Background technique: [0002] In neurobiological research, especially in electrophysiological experiments, it is often necessary to know whether a certain piece of information in the signal is related to a specific behavior after collecting bioelectrical signals, so it is usually necessary to compare the recorded electrophysiological signals with experimental animals. Behaviors are synchronized in time in order to study the interrelationships between electrophysiological signals and relevant behaviors of animals. In the current experimental method, the experimenter usually stores the behavior of the experimental animal in the video tape through the VCR camera while recording the electrophysiological signal for future synchronization with the recorded electrophysiological signal. ...
