title: [Transmission of amplitude-modulated signals in the presynaptic inhibition system of the cat spinal cord].
abstract: In experiments with cats under the hexenal anesthesia it has been found that the transmission of information in multineuronic reflex ring carries out by frequency-dependent way. The optimum frequency subrange corresponds to each meaning of the modulation depth. Appearing signal distortions are accompanied by the phase lead of dorsal potentials with maximum on "resonance" frequency. The mechanism of presynaptic inhibition serves as control command amplifier. For all this the information signal amplitude grows, signal relation to noise increases, noise immunity of information transmission through the neuronic communication channel of multineuronic reflex ring improves considerably.
