ELECTROPHYSIOLOGICAL RESPONSES TO THERMAL STIMULI IN PERIPHERAL-NERVES OF THE SNAIL HELIX-POMATIA L

1. In Helix pomatia single units of the inner lip nerves and the pedal nerves were recorded during thermal stimulation of the lip region and the epithelium of the sole, respectively. 2. 13.3% of all single unit s recorded from the inner lip nerves and 11.7% of the pedal nerve fibr es proved to be sensitive to thermal stimuli. 3. These results suggest that peripheral thermoresponsive structures contribute to the control of behavior leading to avoidance of unfavorable ambient temperatures. (C) 1998 Elsevier Science Ltd.
