Description

technical field

[0001] The present application relates to the technical field of neuromodulation, in particular to a portable dual-channel transcranial ultrasonic stimulation device for neuromodulation. Background technique

[0002] Neuromodulation technology is an important tool for neuroscience research, neural engineering and clinical application. The common neuromodulation methods at this stage include deep brain stimulation (DBS, Deep brain stimulation), transcranial direct current stimulation (tDCS, Transcranial direct current stimulation), Cranial Magnetic Stimulation (TMS, Transcranial magneticstimulation) and Optogenetics (Optogenetics) and Transcranial Ultrasound Stimulation (Transcranial Ultrasound Stimulation, TUS). DBS has micron-level spatial resolution, but its application is limited by surgical trauma and inflexible changes in stimulation targets, and there are risks such as postoperative infection. Although TMS and tDCS have the advantages of being non-inva...
