Description

technical field [0001] The invention relates to a non-injury brain regulation and detection technology, in particular to an integrated device for transcranial magnetoacoustic stimulation and EEG detection. Background technique [0002] Pharmacological or chemical methods to treat neurological diseases are simple to operate, but lack the accuracy of the target area, and neurological diseases are difficult to be cured by drugs and other means. At present, commonly used neuromodulation techniques include: implanted and non-implanted techniques, both of which have their own advantages and limitations. For example: electrical stimulation, such as deep brain stimulation, is mainly used in the treatment of movement disorders through different chronic current stimulation of special nuclei deep in the brain. Although the stimulation is highly targeted, it requires electrodes to be implanted in the brain, and surgery exists. Greater danger. Although the more mature direct current st...

The Chinese patent application number is: 201510021745.0, the name is: transcranial ultrasonic stimulation device and stimulation method, the ultrasonic excitation is integrated on a circuit board, but the ultrasonic echo display can not be real-time changes in brain nerve tissue information with the help of an oscilloscope display

Moreover, the physical mechanism of ultrasound regulation is still unclear. It is based on the above reasons that people continue to explore a new neuromodulation technology, which is simple to operate and does not require surgery. It can also display the waveform of brain nerve tissue in real time.
