Paclitaxel, one of the chemotherapeutic agents clinically used to treat several types of cancer, produces side effects such as peripheral neuropathy, sensory abnormalities, and hyperalgesia. Since hyperalgesia remains after cessation of paclitaxel therapy and becomes chronic, we hypothesize that alteration
