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...
