a neuroregulatory device

Abstract

A neuromodulation device and method for stimulating target neural nuclei. The device generates and emits ultrasonic waves through the ultrasonic generation module, which is conducted by the first conduction module. The directional guide module adjusts the parameter information of the ultrasonic wave according to the position and area of ​​the target nerve nucleus to change the conduction direction of the ultrasonic wave and perform directional conduction; The waveguide module includes multiple artificial structures for replacement, and one artificial structure corresponds to a group of target neural nuclei. The second conduction module transmits the directional conduction ultrasonic wave, so that the ultrasonic focal spot focused by the ultrasonic wave is projected on the target nerve nucleus. The above-mentioned neuromodulation device and method select an artificial structure according to the position and area of ​​a group of target nerve nuclei to be stimulated, so that the ultrasonic focal spot is projected on the group of target nerve nuclei after adjusting the parameter information through the artificial structure. On the mission, to realize the intervention and treatment of brain functional diseases.

Description

technical field [0001] The invention belongs to the technical field of neuromodulation, and in particular relates to a neuromodulation device and method. Background technique [0002] Brain functional diseases such as Parkinson's, epilepsy, depression, etc., are mainly caused by the dysfunction of deep neural circuits in the brain, and multiple neural nuclei in the neural circuits cannot work together. The principle of neuromodulation technology is to improve the function of the neural circuit by stimulating multiple neural nuclei at the same time, so as to achieve the therapeutic effect. [0003] At present, the traditional neuromodulation technology stimulates the nerve nuclei by using an electronic phased array sound field modulation device. Stimulate. The cost of multi-element ultrasonic transducers is high, so the traditional electronic phased array sound field control device is expensive, and the circuit for controlling multiple multi-element ultrasonic transducers i...
