Abstract
SLOW-action potentials have been found in various sensory receptors in response to adequate stimuli. They were first found in the olfactory epithelium of a dog by Hosoya and Yoshida1. Recently, Ottoson2 studied them extensively in the olfactory epithelium of a frog. He showed that the action potential is of a triangular shape, having a steeply rising limb, a round summit and a gradually falling limb in an exponential curve. When the duration of the olfactory stimulus is long, a plateau appears in the middle of the falling limb and continues as long as the stimulation. It is succeeded by an exponentially falling limb at the cessation of stimulation.
