This is the first phase of pain, known as fast pain, because it is not especially intense but comes right after the painful stimulus. [11] In contrast to the hyperalgesia following intense noxious stimuli, prolonged exposure to capsaicin can result in subsequent desensitization.While the discovery of thermosensitive TRP channels has greatly enhanced our understanding of transduction mechanisms of thermal stimuli, findings in animals with selective gene deletions clearly indicate that multiple and yet unknown transduction mechanisms are engaged by thermal stimuli.
