Problems solved by technology

However, since the EEG signal is a non-stationary random signal without ergodicity, and its background noise is also very strong, the analysis and processing of the EEG signal has always been a very attractive but quite difficult research topic.

Abstract

The invention provides an electroencephalogram analysis system used in an electromagnetic radiation environment. The system comprises an event-related potential module, an electroencephalogram recording on-off time control module, a pulse start control module, and an electroencephalogram-pulse transmission synchronous control module. The electromagnetic compatibility modification of the event-related potential module is performed by making the backward voltages on the two ends of the event-related potential module be lower than the breakdown voltage of an amplifying chip, arranging anti-radiation film and making the electrode wire arrangement direction be parallel to the electric field polarization direction. Through the cooperative action of the electroencephalogram recording on-off time control module, the pulse start control module and the electroencephalogram-pulse transmission synchronous control module, pulse microwave transmission and electroencephalogram recording time are accurately controlled, and accurate time control for the pulse microwave transmission and the electroencephalogram recording is realized; when an electromagnetic field module stops electromagnetic pulse radiation, a timing device in the event-related potential module is started and the electroencephalogram recording function is enabled.

Description

technical field [0001] The invention relates to the field of scientific experiment devices, more specifically to an electroencephalogram analysis system used in an electromagnetic radiation environment, in particular to an experimental system capable of synchronously performing pulsed microwave irradiation and electroencephalogram event-related potential analysis. Background technique [0002] Electroencephalogram (EEG) is the overall reflection of the electrophysiological activity of brain nerve cells on the surface of the cerebral cortex or scalp. EEG signals contain a lot of physiological and disease information. In clinical medicine, EEG signal processing can not only provide diagnosis basis for some brain diseases, but also provide effective treatment methods for some brain diseases. In terms of engineering applications, people also try to use EEG signals to realize the Brain-Computer Interface (BCI), and use the differences in EEG signals for different sensory, motor o...
