It is well known that when the tongue is stimulated, secretory potentials are recorded in the human parotid. When these potentials are continuously recorded, the time-course of these secretory potentials would be clarified. In this experiment, the individual time-course of secretory potentials sometimes differed among each other. The results obtained are summarized as follows. 1) At times the time-course of secretory potentials in one subject did not show the same patterns in spite of the similar salivation volume (2.5-3.0ml). 2) The deflection in secretory potential recorded on the suction capsule is about -10 mV, while the deflection recorded on the mucous membrane at about 10 mm distant from papilla parotidea and on the skin over parotid gland are -0.3 mV. The difference in secretory potentials due to the different position of recording electrodes is great. 3) The time-course of secretory potentials showed different patterns due to the different psychological conditions of subject (hunger, irritation etc. ). 4) The negative deflection in secretory potentials were seen in 4 subjects, while the positive deflection was seen in one subject.
