[The neurophysiological changes in the taste reactions of the frog glossopharyngeal nerve evoked by the chronic administration of ethanol].
The latency of impulse responses of taste receptors to different taste stimuli was studied and frequency-temporal characteristics of the responses were analysed during chronic ethanol injection. It was shown that the latency of taste responses depending un the type of taste stimuli was increased 2-4.5 times after 7-14 days of ethanol injection. The latency of responses tended to shortening within 30 days of ethanol injection. The continued ethanol injection brought about a renewal of increase in the response latency. The changes in the dynamics of the impulse taste responses to salt and sour stimuli were found within 90 days of ethanol injection. The findings indicate that both the transduction of taste stimuli and the conduction of sensitive nerve fibres are disturbed.
