The oscillation from pacinian corpuscles to external stimuli in cat mesentery

Abstract

Single Pacinian corpuscles isolated from cat mesentery elicited fast-adapting responses and/or oscillation to displacement and vibratory stimuli at temperatures of 24-43 degrees C. The displacement threshold of oscillation increased by decreasing the temperature of the room or of the corpuscles to below 26 degrees C. Further cooling made the corpuscles elicit only fast-adapting responses to displacement stimuli of identical strength. When a single Pacinian corpuscle was stimulated by the same displacement the impulse patterns depended on the temperature of the experimental plate on which the corpuscle was situated. It is therefore suggested that, in temperatures higher than 28 degrees C and lower than 43 degrees C, constant displacement stimuli or vibratory stimuli (10-0.01 Hz) induced oscillation of the receptor potential from the Pacinian corpuscles.
