[Electrical potentials of the cat parotid gland monitored from the body surface]

Correlation of the changes of the electrical potential on the parotid gland surface and on the corresponding body surface in the stimulation of the secretory nerves and under other effects was shown in cat. The absence of the potential gradient with the electrode on the body surface confirmed the macrostructure of the total field of the salivary gland. The experimental results point to the glandular origin of the electrical responses on the body surface.
