Interactions between inhibitions of sympathetic nerve discharge (SND) to consecutive stimulations of A- and C-fibres in the aortic nerve and superficial peroneal (SP) nerve have been studied in rabbits anaesthetized with urethane and chloralose. SND was recorded from the renal nerve. At interval of 10 s following conditioning stimulation of SP nerve the test response of SND to activation of C-fibres (interaction SP-C) amounts to 83.7 +/- 7.5% (means +/- SE) of control. After applying both stimulations to the same SP nerve (interaction SP-SP) the test response of SND is significantly lower amounting to 56.3 +/- 3.9%. Comparable decrease of the effect of conditioning stimulation of one type of afferents on the test response to activation of other type of fibres was observed at interval of 10 s in two other interactions (SP-A and C-A). In seven interactions the conditioning stimulation of one type of fibres had no effect on the test response to stimulation of other type of fibres. This was found in one interaction at interval of 10 s (C-SP), in four interactions at interval of 20 s (SP-A, C-SP, SP-C and C-A) and in two interactions at interval of 40 s (SP-A and SP-C). Conditioning stimulations used in above interactions depressed the test responses to activation of the same type of fibres. It is suggested that the decrease or suppression of the effect of conditioning stimulation of one type of afferents on the test response of SND to activation of other type of fibres is related to disinhibition of this response.

D009413	Nerve Fibers, Myelinated	A class of nerve fibers as defined by their structure, specifically the nerve sheath arrangement. The AXONS of the myelinated nerve fibers are completely encased in a MYELIN SHEATH. They are fibers of relatively large and varied diameters. Their NEURAL CONDUCTION rates are faster than those of the unmyelinated nerve fibers (NERVE FIBERS, UNMYELINATED). Myelinated nerve fibers are present in somatic and autonomic nerves.
