FPGA experimental platform based on multi-electrode array feedback synchronous control of neural nuclei

Abstract

The invention provides a nervous nuclei feedback synchronous control FPGA experimental platform based on a multi-electrode array. According to the experimental platform, a nervous nuclei which is measured and taken by the multi-electrode array is taken as an experimental object, an FPGA is taken as a lower computer, and a man-machine operation interface edited by an LABVIEW is adopted for displaying data of the multi-electrode array and setting control parameters; the FPGA is used for analyzing and processing experimental data of the multi-electrode array, an upper computer sets parameters through the man-machine operation interface, and thus synchronous control of the nervous nuclei is achieved. The nervous nuclei feedback synchronous control FPGA experimental platform based on the multi-electrode array has the advantages that based on multi-electrode array experiments, synchronous analysis and feedback synchronous control of the nervous nuclei are achieved by using the FPGA experimental analysis platform which operates in a high speed, the control parameters such as control points and feedback intensity are set through the man-machine operation interface of the upper computer, synchronous characteristics of the nervous nuclei are analyzed under different control effects, and thus the synchronizing or desynchronizing control effect of the nervous nuclei is achieved.

technical field [0001] The invention belongs to the field of biomedical engineering, and relates to the acquisition and processing technology of bioelectrical signals, in particular to a multi-electrode array-based neural nuclei feedback synchronous control FPGA experiment platform. Background technique [0002] With the development of economy and society, the problem of population aging is becoming more and more serious, and the incidence of mental diseases such as Parkinson's disease, Alzheimer's disease, and epilepsy is increasing. Further detection and observation of the response behavior of the nervous system will help people to further understand Understanding the function of the nervous system and further understanding the pathogenesis of various neurological diseases are of great significance to the diagnosis and treatment of neurological diseases. Multi-electrode arrays are widely used in basic biology and medical diagnosis because of their ability to detect and rec...

AI Technical Summary

Problems solved by technology

[0005] However, the existing technology is still in the basic stage, and there is no experimental platform for feedback synchronous control based on multi-electrode arrays.

So far, the research on the synchronization of neural nuclei is mainly based on software or hardware simulation of nuclei activity. The nuclei activity simulated by software is not real-time, and the structure of the neuron network model implemented by hardware is relatively simple, and its practical application value is low.
