Influence of receptor-receptor fibres on the spontaneous afferent activity from semicircular canals in the frog (Rana esculenta).
The influence of the efferent vestibular system having been eliminated, the spontaneous activity of afferent fibres of the ampullary nerves of the horizontal and vertical anterior semicircular canals was recorded in the frog. By stimulating the ampullary nerve of one of these two canals while recording on the other, as well as by sectioning branches of the vestibular nerve and then using statistical methods, it is shown that receptor-receptor fibres have an inhibitory action on afferent activity from the horizontal and vertical anterior semicircular canals.
