Closed-loop feedback type opto-acoustic-electromagnetic integrated brain work rhythm adjusting device

Abstract

The invention discloses a closed-loop feedback type opto-acoustic-electromagnetic integrated brain work rhythm adjusting device. The closed-loop feedback type opto-acoustic-electromagnetic integrated brain work rhythm adjusting device comprises an electroencephalogram signal detection module, an electroencephalogram signal preprocessing module, an adjusting controller and an opto-acoustic-electromagnetic integrated adjusting module, and the closed-loop feedback type opto-acoustic-electromagnetic integrated brain work rhythm adjusting device, a detection brain area and a response brain area jointly form a closed-loop feedback type structure. Signals collected by the electroencephalogram signal detection module from the detection brain area are preprocessed by the electroencephalogram signal preprocessing module and then transmitted into the adjusting controller to calculate the difference value between the signals and a reference value, an opto-acoustic-electromagnetic integrated nerve adjusting signal is generated, the opto-acoustic-electromagnetic integrated adjusting module is controlled to adjust the a response brain area of a target brain, therefore, the working rhythm of the target brain reaches a reference value. According to the device, working rhythm adjustment gain far beyond single stimulation can be provided, a plurality of working rhythms of the brain can be adjusted with different gains so as to deal with complex nerve dysfunction, and the closed-loop feedback structure is adopted, so that long-term use of a patient in various scenes is facilitated.

Description

technical field [0001] The invention relates to a technology for adjusting brain working rhythm, in particular to a closed-loop feedback photoacoustic and electromagnetic integrated brain working rhythm adjusting device. Background technique [0002] EEG working rhythm reflects the level of coordinated activity of a large group of neurons. It is an important macroscopic indicator of brain activity and is also an important symbol of a series of neurological and mental diseases. It has been proved that changes in EEG working rhythm can also promote brain activity in turn. Changes in the activity state help to suppress abnormal EEG, restore normal working rhythm, and further help to repair functional impairments such as cognition and memory. Studies have shown that external stimuli can change the working rhythm of EEG, including changing the specific frequency components in the working rhythm of EEG. The tonic stimulation of specific frequency band signals directly to the targ...

Problems solved by technology

[0005] A single light and sound stimulus is indirectly projected to the target deep brain area through the visual / auditory neural pathway. The strength of the stimulus signal is limited by the tolerance limit of human senses. Too strong or wrong signals will cause visual and auditory discomfort, damage, mental A series of side effects including damage, etc., so the regulation effect on the working rhythm of the brain is limited;

[0006] Time-domain / frequency-domain electromagnetic stimulation, such as TMS, tDCS, tACS, etc., need to penetrate the scalp and skull to act on deep brain areas, and the effect decreases with increasing depth of the target area. At the same time, it is not suitable to use high-power and strong signals. The regulation effect of brain working rhythm is limited;

[0007] The nervous system has the characteristics of stress adaptation. Tetanic stimulation signals of a single type and waveform can only cause short-term EEG rhythm changes. Fixed stimulation types and stimulation signals will gradually reduce the stress response to the point that it is difficult to cause effective changes. level and cannot be used for a long time;
