摘要: Abstract Tooth pulp-driven (TPD) neurons are found in the oral area of first somatosensory cortex (SI) cat. They have been classified according to their discharge patterns response electrical stimulation tooth pulp: fast (F) type, slow (S) and a (Fa) type accompanied by afterdischarges. The characteristics each TPD neuron were investigated cats anesthetized with nitrous oxide halothane. In surface distribution, there was no biased localization for any types. However, F-type receiving input from mandibular tended be more medially than F-types maxillary input. These did not change firing pattern even when stimulus intensified. Mean threshold pulp 7.8 ± 1.6V lower that S-type (16.3 3.0V). Graded increases produced progressive frequency both types neurons. An analysis power function relation vs. demonstrated exponent about 2.0, being significantly larger compared 0.8 value F-type. mean number pulps afferent an 1.6, 4.8 or 4.3 Fa-type. results suggest may play important part localizing pulpal pain recognizing intensity other
