[Changes in transmission efficiency in synapses of the dorsal horn of the cat spinal cord during repeated activation of cutaneous afferents].
Inhibition dynamics of certain components of the spinal cord potentials under low frequency stimulation of cutaneous nerves was studied in acute experiments on cats. The experimental data obtained were approximated by the theoretical curve on the assumption that the two-pool model of the transmitter storage was applicable. An increase of the mediator replenishment intensity during rhythmical stimulation has been demonstrated. The results obtained were similar to those obtained from monosynaptic reflex investigations, that demonstrates the likeness of action mechanisms for different afferent synapses.
