[Motivational dependence of centrifugal "tuning" influences on taste receptors].

: Bioelectrical activity was registered in the central sector of the glossopharyngeal nerve. The impulsation was processed on a specialized computer "ATAK-350" in the real-time regimen. Interval histogramms were made, based on the result of survey of 500 inter-impulse intervals. It has been established that during a 4-day food deprivation bimodal distribution of inter-impulse intervals takes place. The first maximum occurs within 10-15 ms, the second--within 190-200 ms. After the irritation of the stomach by the rubber balloon, containing 1.5-2.0 ml of water, monomolar distribution of inter-impulse intervals (with the maximum in the range of 55-60 ms) takes place. It is believed that specific motivating excitement is manifested not only in central structures, but also involves peripheral receptor structure and tunes them to accept adequate stimuli.
