摘要：

The paper introduces a new approach to the estimation of the EEG-EMG coherence, which is used to examine the functional connection between a human brain and muscles. A typical EEG-EMG coherence estimation, with a magnitude squared coherence (MSC) barely exceeding 0.15, is enhanced so that MSC reaches or even goes above 0.5. The proposed method is mathematically analyzed, and its properties are discussed. Additionally, the paper includes several EEG-EMG coherence analysis results, with MSC exceeding 0.5.
