Corticomuscular coherence between the primary motor cortex (M1) and hand muscle electromyograms (EMG) occurs at approximately 20 Hz but is rarely seen at approximately 10 Hz. This is unexpected, because M1 has oscillations at both frequencies, which are effectively transmitted to the spinal cord via the corticospinal tract. We have previously speculated that a specific "neural filter" may selectively reduce coherence at approximately 10 Hz. This would have functional utility in minimizing… CONTINUE READING
