Corticomuscular Coherence is referred to synchrony in the neural activity of brain's cortical areas and muscle. The neural activities are recorded by electrophysiological signals from brain (e.g. EEG, MEG, ECoG, etc.) and muscle (EMG).

Physiology

Corticomuscular Coherence was initially reported between MEG and EMG ^[1] and later extended to EEG-EMG and other signals.

Mathematics and Statistics

A classic and commonly used approach to assess the synchrony between neural signals is to use Coherence_(signal_processing)^[2].
