[Study of the "stimulus--excitation" function in the peripheral portion of the frog taste analyzer].
The intensity of glossopharyngeal nerve afferent discharges in the frog was studied during stimulation of gustatory receptors by caffeine, acetic acid, saccharose and sodium chloride ranging widely in the concentration changes. It was shown, that the function "stimulus-exitation" for the summary discharges in response on the coffeine and acetic acid was being logaryphmic. The character of off-effects dependence on the concentration of bitter and sour stimuli. Was proved to be the same. The curve "stimulus-exitation" for the saccharose was "S" shaped, but for the sodium chloride it might be described by the power function with the exponent equal 0,8.
