title: [Rsponses of the primary afferents of the frog lateral semicircular canal to caloric stimuli following section of the eighth nerve].
abstract: In curarized Rana temporaria, after transection of the 8th nerve, responses of 75 primary afferents of the LSC nerve to short local caloric stimule (0.5--12 degrees C over the canal temperature) creating theexcitatory current of LSC endolymph, were studied. In 41 per cent of the units (group A) the maximal (peak) frequencies (PF) of responses were shown to be associated either by linear or semilograithmic relations with the peak temperature (PT). In 23 per cent of the units (group B), PFPS revealed saturation at PT 8-12 degrees C. In 29  per cent of the units (group C), PFs were associated with PTs first by direct and then -- at increasing PTs-- by reverse proportionality. Duration of group A responses was related to PTs either in linear or semilogarithmic way. Comparison with previous data obtained in identical conditions but with intact 8th nerve indicates no noticeable difference in responses where efferent control was excluded.
