Abstract

The invention provides a real-time neurofeedback device, system, method and computer storage medium, and relates to the technical field of neurofeedback. The real-time neurofeedback device includes an acquisition module, a decoding module, an encoding module, and a feedback modulation module. After the acquisition module, the decoding module, an encoding module, and the feedback modulation module are electrically connected in sequence, the feedback modulation module is connected to the acquisition module. The modules are connected to form a closed-loop, dynamic real-time neurofeedback device. The present invention solves the problems existing in the applicability, effectiveness and accuracy of the existing neurofeedback technology, realizes self-adaptive, dynamic and precise control of the amplitude and phase of the specific EEG rhythm, and avoids the Differences in effect due to factors such as experience.

Description

technical field [0001] The invention relates to the technical field of neurofeedback, in particular to a real-time neurofeedback system and method. Background technique [0002] Neurofeedback is a kind of biofeedback. It uses various physiological instruments to convert the activity state of the human brain into information that people can understand and present it. Through people's conscious adjustment of their own physiological and psychological states, it can enhance cognitive ability and heal the spirit. diseases etc. The EEG neurofeedback technology collects the user's EEG signal and transmits it to the calculation module. After the analysis of the calculation module, the energy distribution of the EEG rhythm wave reflecting the user's current memory level is presented to the user in a graphical way. Instruct users to use feedback signals to regulate and strengthen specific brain wave rhythm signals. The human brain will generate a small amount of current during opera...
