coherence between muscle & brain
spectral peaks are 1 way to assess rhythmic activity in the brain, but there are also others. below is data from my own brain, showing only a small peak exceeding 1/f-noise. but corticomuscular coherence is very high, the synchrony between EEG & contracted thumb muscle activity. pic.twitter.com/W38XFsOIkS
