FPGA-based multi-electrode array simulation experiment platform

Abstract

The invention provides an FPGA-based multi-electrode array simulation experiment platform. The experiment platform comprises an FPGA development board and a principal computer which are connected with each other via a USB interface. The FPGA development board is used for implementing an STN neuron network model and a multi-electrode array algorithm. The software interface of the principal computer is designed based on LabVIEW, and the principal computer communicates with the FPGA development board. With the FPGA neural network experiment platform which is taken as a biological neuron network, free of animal experiment and based on high-speed operation, synchronous record of multiple sites of the field potential of a neuron network through a multi-electrode array is realized, and the consistency with real biological neurons in time scale can be ensured. A visual study platform closer to a real neural network is provided for the study of the discharge mechanism of a sub-thalamic nucleus STN nuclei and the study of a multi-electrode array. The platform is of important practical value to the study and treatment of a variety of neurological diseases including the Parkinson's disease.

Description

technical field [0001] The invention relates to biomedical engineering technology, in particular to an FPGA-based multi-electrode array simulation 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. However, the current auxiliary treatment technology is still very limited. Further detection and observation of the response behavior of the nervous system will help people to further understand the function of the nervous system, and further understand the pathogenesis of various neurological diseases, which is of great significance to the diagnosis and treatment of neurological diseases. Multi-electrode arrays are widely used in basic biology and research because of their non-invasive long-term, multi-site detection and recording of the firing activities o...
