The amplitude of the electrical change from parotidea areas with tongue stimulation shows various amplitudes i.e. the amplitude of the electrical change from the papilla parotidea have been shown as 18 mV, but six other records (three from the mucous membrane around the papilla parotidea, and three from the cutis over the parotidea gland) show it to be under 0.8 mV. When the stimulated saliva was flowing through the system hear, the time till culmination of the electrical change, which was recorded from near the papilla parotidea was shorter than the time till culmination far from the papilla parotidea. The saliva which evoked the higher electrical change was collected, and about 4 minutes after the stimulation (when the electrical level of the papilla parotidea had returned to the before stimulation (resting) level), this collected saliva was injected into a Carlson type cup. The electrical change evoked by this injection and the amplitudes of the evoked electrical charge were 75〜90% of the amplitude of the electrical change by tartaric acid stimulation.
