[Excitation and inhibition of highly excitable reflex curves in chronically denervated albino rats].
The animals were selected with spastic syndrome and enlarged amplitude of monosynaptic segmental reflex responses in 2-4 weeks after cutting of spinal cord at Th10 level. The processes of excitation and inhibition in lumbar segments of these animals were investigated. A reliable decrease of the presynaptic inhibition intensity was found after cutting of spinal cord. It is supposed that reduction of presynaptic inhibition plays a definite but not determinant role in developing hyperreflexia in chronically spinal white rat.
