Description

technical field [0001] The invention relates to the field of brain signal processing, in particular to an adaptive brain nerve signal processing method and system. Background technique [0002] In the field of brain nerve signal research for motor function, a large number of brain nerve signals are usually collected through the front-end brain-computer interface. Due to the low spatio-temporal resolution of the signals collected by the front-end and the differences in the signal characteristics of specific behaviors, a large number of raw data of brain nerve signals need to be processed and analyzed by specific algorithms in order to cooperate with the back-end to perform behavior recognition and matching of neural signals. Decoding control and other further research. Therefore, there is a need for a brain signal processing method and system capable of processing a large number of neural signals. [0003] The analysis and processing of neural signals involves a variety of ...
