Abstract
Thermal stimuli were applied to the upper surface of the tongue of the cat. The stimuli ranged from 40°C to 10°C and were changed in cold steps of 5°C, each temperature lasting 2 min. Afferent impulses of single specific cold fibers from the lingual nerve were analysed by a computer program. About 90% of the fibers showed bursts under static conditions. The bursts began as doublets at the temperature of maximal average frequency. This temperature varied from 40°C to 15°C in different fibers, the average being 30°C. The parameters burst period, burst duration, pause duration, intraburst interval and spikes per burst increased monotonically from 30°C to 15°C. The possible physiological significance of the burst pattern is discussed.
