Межсегментарные взаимодействия систем пресинаптического торможения в спинном мозге
Intersegmental interaction of systems of presynaptic inhibition in a spinal cord

Summary/Abstract: In this message the effect of stimulation of nearest dorsal roots in segments L5 – L7 of spinal cord on N1 and P components of the cord dorsum potential is described. The changes of these components at simultaneous stimulation of dorsal roots and at the “moved in time” stimulation are shown. We point that such spatial zones of activity of N1-component neurons are independent, but the same zones for the neurons of substantia gelatinosa overlap. The causes of such spatial property of neurons of spinal cord are considered.
