Neural feedback training system and neural feedback training method on basis of optical brain imaging

Abstract

The invention provides a neural feedback training system and a neural feedback training method on the basis of optical brain imaging. A trainee completes training tasks to achieve training purposes in the neural feedback training method. The neural feedback training method includes that neural activity data of the trainee are acquired by optical brain imaging equipment in a training task completion procedure; neural activity intensity indexes of a specific function system of the brain of the trainee are extracted from the neural activity data and are displayed to the trainee as feedback information; and the trainee adjusts training strategies according to the acquired feedback information, so that neural activities of the specific function system of the brain of the trainee are trained and are developed towards a target. The neural activity data of the trainee are acquired by the optical brain imaging equipment in the neural feedback training method. Compared with electroencephalogram and magnetic resonance imaging, the optical brain imaging is high in targeting, the optical brain imaging equipment is low in cost, and accordingly the neural feedback training system and the neural feedback training method are applicable to long-term neural feedback training.

Description

technical field [0001] The invention relates to a neurofeedback training system based on optical brain imaging, and at the same time relates to a neurofeedback training method based on optical brain imaging. Background technique [0002] Neurofeedback is to collect the individual's brain neural activity online and feed it back to itself, so that it can autonomously adjust the brain activity and achieve the purpose of changing its cognition and behavior. Through the intervention of specific brain functions, the treatment and rehabilitation of patients with brain diseases can be realized, or the cognitive abilities (such as learning and memory) of healthy people can be improved. [0003] Researchers use electroencephalography (EEG) or functional magnetic resonance imaging (fMR I) to observe the neural activity indicators of the target brain area that they want to adjust, and feed them back to the trainees through audio-visual channels, so as to guide the trainees to try to adj...

AI Technical Summary

Problems solved by technology

[0005] However, there are still many problems to be solved in the existing neurofeedback system

For the neurofeedback system based on EEG, because the spatial resolution of EEG is extremely low, it is difficult to locate the training brain area, and the relationship between EEG rhythm components and cognitive function is not yet clear, so the training target Poor performance, its application is greatly limited

Although the neurofeedback system based on magnetic resonance imaging overcomes the shortcomings of the EEG system to a certain extent, due to the high cost and use cost of magnetic resonance imaging equipment, the equipment is huge and cannot be moved at will, so it can only be used for laboratory research. , it is impossible to use it for clinical long-term treatment training
