Abstract

The invention relates to a data compression device and method for a high-channel neural signal, the data compression device is used for compressing a high-throughput neural signal to output a neural signal with a low data volume, and the data compression device comprises a neural signal acquisition module, a control module, a transmission module and a cache module, the neural signal acquisition module is used for acquiring a high-throughput neural signal, preprocessing the acquired high-throughput neural signal to obtain a digitized neural signal, and outputting the obtained digitized neural signal to the control module; the control module is used for performing data compression on the digitized neural signal output by the neural signal acquisition module to obtain a neural signal with a low data volume and outputting the obtained neural signal with the low data volume to the transmission module to complete wireless transmission of a high-throughput neural signal; and the cache module is used for caching the digitized neural signal. The neural signal is greatly compressed by the control module and then is wirelessly transmitted, so that the wireless transmission of the high-channel neural signal is realized.

Description

technical field [0001] The invention relates to the field of biomedical engineering, in particular to a data compression device and method for high-channel neural signals. Background technique [0002] Current research shows that a variety of nervous system diseases, including Parkinson's disease and Alzheimer's disease, are closely related to the firing activity of neurons in the central nervous system, and nerve electrical signals show abnormal activity characteristics and patterns. Therefore, the high-throughput detection of weak neural electrical signals in brain tissue and the study of the dynamic process of electrophysiological signals under different physiological and pathological conditions are of great importance to the study of the pathogenesis of nervous system diseases, the mechanism of action of related drugs, and the The curative effect evaluation has important significance and potential application value. In order to suppress external noise interference and m...
