Simons CT, Gogineni AG, Iodi Carstens M, Carstens E (2002) Reduced aversion to oral capsaicin following neurotoxic destruction of superficial medullary neurons expressing NK-1 receptors. Brain Res 945:139-143. doi: 10.1016/s0006-8993(02)02913-x
Summary: Capsaicin-induced irritation of the dorsal anterior tongue is mediated by nociceptors expressing VR-1 receptors. The role of NK-1 receptor-expressing neurons during the ingestion of capsaicin was examined by injecting 20 µl of 2.27 µM SP-SAP (Cat. #IT-07) into the cisterna magna of rats. Lesioned rats consumed significantly more water containing high concentrations of capsaicin than control animals.
