Abstract

Results of a previous study demonstrated transformation of the sustained activity of a muscle into rhythmic, tremor-like activity by stimulation of different motor centers. The optimum for this transformation was in the 4-7 Hz frequency band (resonance band). Sustained rhythmic stimulation with stimuli at 0.1-20 per second caused a normal frequency curve of the H reflex in subjects with intact motor systems. The resonance phenomenon of the frequency curve of the H reflex was in agreement with that found in previous studies stimulating the different motor centers. As this requires connections between spinal and higher motor centers, it is suggested that this investigation is appropriate for a detailed functional study of spinal cord lesions.
