基于相干性的多频段脑肌电信号双向耦合分析
Multiband EEG-EMG Bidirectional Coupling Analysis Based on Cortico-Muscular Coherence
摘要
Abstract
For CMC have the limitation that can't determine the direction of the coupling,different functional areas of EEG signals and the EMG signals are adopted to realize the bidirectional coupling analysis,according to the bidi-rectional transmission of neuromuscular information. The multi-band coupling analysis of EEG-EMG signals under multi-grip mode is performed in the different functional areas. Through the downstream( EEG->EMG) and upstream (EMG->EEG) analysis,it is found that the signal energy of EEG,amplitude and coupling strength of coherence shift to higher frequency with the increase of grip strength. Compared with method based on granger causality rela-tion, the feasibility and advantage of the coherence method are verified in the bidirectional coupling analysis of brain-muscle connectivity. The results of the study provide the basis for the two-way information decoding of hand motion and the analysis of upper limb dysfunction.关键词
