Zusammenfassung

Cortico-muscular coherence (CMC) is an established method for the analysis of interactions between cortical and muscular activity. CMC can be studied noninvasively with millisecond precision using multi-channel EEG/MEG recordings. Previous CMC studies have been primarily based on bipolar and Laplacian transformations of EEG -approaches which do not necessarily guarantee an optimal detection of coherence. Here, we propose a novel method, which provides an optimal solution for finding spatial filters. The core idea is to use multiple regression where narrowly filtered EEG signals serve as predictors and the electr…
