Brain functional activity detection and regulation combined method, device and system

Abstract

The invention provides a brain functional activity detection and regulation combined method, device and system. The brain functional activity detection and regulation combined method comprises the steps of firstly, obtaining an electroencephalogram and / or cerebral blood oxygen signals of a monitored person; then, according to the electroencephalogram and / or cerebral blood oxygen signals of the monitored person, extracting brain functional activity features of the monitored person; finally, according to a corresponding relation between preset brain functional activity features and a regulationmode, determining a regulation mode matched with the brain functional activity features of the monitored person. According to the brain functional activity detection and regulation combined method, the brain functional activity degree of the monitored person can be monitored in real time, change of the brain functional activity of the monitored person can be found timely, the accurate and effective regulation mode can be matched according to the current brain functional activity features of the monitored person to interfere with and regulate the emotion state of the monitored person timely, thus the brain functional activity degree of the monitored person maintains at an appropriate level, attention level improvement of the monitored person is facilitated, and the dysphoric mood of the monitored person slows down.

Description

technical field [0001] The invention relates to the technical field of cognitive neuroscience, in particular to a combined method, device and system for brain function activity detection and regulation. Background technique [0002] The processes of human cognition and behavior are all realized through the functional activities of the brain. A single activity in which a person is required or forced to maintain brain function for extended periods of time during certain tasks or in certain disease states. For example, in the driving process of motor vehicles, ships, airplanes, etc., drivers are required to maintain a high degree of concentration under continuous pressure, that is, they need to focus on relatively monotonous and boring operating tasks for a long time. At the same time, operators must be able to make timely and correct responses to instantaneous changes. In addition, for some brain diseases, patients will also show a similar single activity of brain function. ...

AI Technical Summary

Problems solved by technology

[0003] In the above state, whether it is a task that actively requires a single activity of the brain, or a disease that is forced to a single activity of the brain, it will lead to high-load brain activity, and high brain load often leads to mental fatigue, which reduces the level of arousal after fatigue , the decline in brain cognitive function will eventually reduce people's attention level, which poses a great safety hazard

[0004] However, due to the complexity and changeability of brain activities, previous studies on attention were mostly subjective assessments, and the objectivity and reliability were limited to a certain extent. conditioning to increase the level of human attention
