System for transcranial ultrasonic stimulation of mouse and synchronous acquisition of electroencephalogram and electromyogram signals

Abstract

The invention discloses a system for transcranial ultrasonic stimulation of mouse and synchronous acquisition of electroencephalogram and electromyogram signals and relates to the field of transcranial ultrasonic stimulation research and synchronous signal acquisition. The system comprises a transcranial ultrasonic stimulation module, a pulse transcranial ultrasonic signal generation module, a brain myoelectric signal acquisition and processing module and a power supply. The device has a series of advantages of stable signal acquisition, strong expansion storage capacity, portability, small size, easiness in operation and the like, and can be effectively applied to real-time synchronous acquisition of electroencephalogram and electromyogram signals of conscious and freely movable mice in transcranial ultrasonic stimulation experiments of various samples. Moreover, the storage module is expanded, and the problems of overlarge storage amount of long-time use data, distortion of wirelesstransmission data and the like are avoided. The system is convenient for subsequent off-line processing of brain myoelectric signals stimulated by transcranial ultrasound, and provides technical support for future mechanism research of transcranial ultrasound stimulation and clinical application of neuromodulation technology.

Description

technical field [0001] The invention relates to the field of research on transcranial ultrasonic stimulation and signal synchronous acquisition, and is applied in the synchronous acquisition of brain electromyography stimulated by transcranial ultrasonic stimulation of mice, specifically a mouse transcranial ultrasonic stimulation and synchronous acquisition system of brain electromyographic signals. Background technique [0002] Neuromodulation technology has received extensive attention in both neuroscience research and neuroengineering applications in recent years. Neuromodulation refers to the process of using mechanical, physical and chemical stimuli such as light, electricity, magnetism, sound, and temperature to act on the nervous system (organs, tissues, cells, body fluids, etc.) of an organism and cause a response. The regulatory effect can be divided into two types according to the enhancement of the excitability of the nerve or the enhancement of the inhibition of...

AI Technical Summary

Problems solved by technology

However, the equipment is relatively large, the structure is single, and there is no device for synchronous acquisition of EEG signals, so it is impossible to obtain synchronous EEG signals at the same time as ultrasonic stimulation
