Abstract

A multimode radio computer interactive device of integrated visual monitor consists of CCD video camera, microelectrode, collection and amplification circuit, transmission circuit, computer detection and analysis unit. It is featured as setting various irritative modes on microcomputer for detecting and analyzing and sending them remote end circuit through radio transmission module; collecting, amplifying filtering and D / A converting animal neural electric information by microelectrode then transmitting it to microcomputer; collecting animal behavior by CCD video camera and recording it in microcomputer simultaneously.

Description

technical field [0001] The invention belongs to a device in the field of medical technology, and in particular relates to a multi-mode wireless brain-computer interaction (BCI) device integrated with visual monitoring. The device adopts a wireless connection mode and can simultaneously video record the behavior of experimental animals. It is especially suitable for different modes of stimulation to freely moving animals to train and control their behavior. Background technique [0002] BCI is a system that realizes communication and control between the brain and computers or other electronic devices based on EEG signals, and is a new way of human-computer interaction. In recent years, the research on BCI has gradually risen, and some practical progress has been made. Such as: 1. Cochlear implants and artificial eyes: composed of external signal processors, transmission circuits, internal stimulation generation circuits and electrodes, to achieve auditory or visual coding st...
