1 All of 30 PGL neurons recorded responded to intracarotid injection of capsaicin with an increase in spontaneous discharge rate from 12.6 +/- 0.7 to 20.9 +/- 1.1 spikes/s (P < 0.001); (2) In 10 units, the excitatory response of PGL neurons to intracarotid injection of capsaicin was significantly inhibited by pretreatment with the vanilloid receptor (capsaicin receptor) antagonist ruthenium red (200 mmol, 0.1 ml). Capsaicin transient receptor potential cation channel, subfamily V, member 1 Rattus norvegicus
