... was depolarized and, therefore, the membrane potential responses recorded are receptor potentials to the substances examined. The amplitude of the responses increased as the concentration of applied alkaloid increased, but tended to saturate at high concentrations ( Figs 1 – 3 ). These results suggest...

...Yukio Okada; Takenori Miyamoto; Toshihide Sato ABSTRACT The ionic mechanism underlying the receptor potential induced by a deionized water stimulus was studied in frog taste cells with conventional microelectrodes. The taste cells located in the proximal portion of the tongue generated...

...Yukio Okada; Takenori Miyamoto; Toshihide Sato ABSTRACT The ionic mechanism underlying the receptor potential in frog taste cells induced by sugar stimuli was studied with conventional microelectrodes by replacing the superficial and interstitial fluids of the tongue with modified solutions...

... of receptor cells in the temporal organ ranged from –25 to –59 mV with an average of –39mV (N = 21). Input resistance ranged from 10 to 46MQ with an average of 22-6MQ (N= 16). Receptor cells responded to a carbon dioxide stimulus with a graded hyperpolarizing receptor potential, which reduced impulse...

...S. A. Dimitracos; M. Tsacopoulos ABSTRACT In the honey-bee drone retina (Apis mellifera) oxidative metabolism is carried out largely by the photoreceptors. We have studied the effects of a transient inhibition of this metabolism, by recording receptor potential simultaneously with measurements...

...Youko Satow; A. Don Murphy; Ching Kung ABSTRACT A depolarizing receptor potential produced by mechanical stimulation was studied in pawn mutants of Paramecium tetraurelia bathed in TEA solution. The potential was dependent upon the strength of the mechanical stimulation until a maximum response...
