[The coding of frequency-modulated signals by the presynaptic control system].
Mechanism of presynaptic inhibition transforms frequency-modulated sensory signals amplitude-frequency-modulated reaction of potentials of dorsal side of spinal cord. Frequency regulation is characterized by a wide threshold range which is several times higher than amplitude regulation mode. Neuromuscular system of motor apparatus is a kind of impulse-frequency detector. The system isolates analogous amplitude changes of mechanic movements by demodulation of frequency-modulated dorsal potentials. The detection mode is facilitated by preliminary transformation.
