The rhythmic properties of the motor system.
The resonance properties of the motor control circuits are basic features of the motor system. From our results, it can be concluded that, when the normally existing suppression mechanism weakens, external stimuli or internal impulses may elicit oscillations in the circuits according to the resonant frequency, and tremor will appear. It seems that the resonant frequency is between 5 and 8 Hz, as demonstrated by rhythmic voluntary movement, rhythmic elicited reflex movement and rhythmic modulated voluntary movement modulated by the stimulation of the central motor system.
