title: Morphological evidence that reline SMR and human mu are analogous rhythms.
abstract: In cats implanted with epidural screw electrodes over sensorimotor cortex, various recording montages were used to observe the waveform of the sensorimotor rhythm (SMR). It was found that in bipolar recordings spanning the crus, SMR exhibited a wicket-shaped waveform comparable in shape and polarity to the human mu rhythm. Based on previously reported topographic and functional similarities of feline SMR and human mu, and on the present data demonstrating morphological similarities, it appears that feline SMR is the first proven feline model of a spontaneous human ieeg rhythm.
