Summary: Researchers shed light on the mechanism that drives the uncontrollable urge to scratch an itch. Itch has resisted many attempts to be classified as any one type of sensory experience. Sensation of itch evokes scratching behaviors, and the pleasant sensations transmitted by scratching may play an important role in the induction of the itch-scratch cycle (Mochizuki and Kakigi, 2015b). Itching can be triggered by a wide range of causes, including allergic reactions, skin conditions, irritating chemicals, parasites, diseases, pregnancy, and cancer treatments. In future studies, Sun and his team plan to investigate which molecules in the Tac1-expressing periaqueductal gray neurons can be targeted by drugs. In the new study, the researchers first recorded from periaqueductal gray neurons in freely moving mice that were induced to scratch through injections with either histamine or an antimalarial drug called chloroquine. For example, you might say, “My mosquito bites really itch.” Less commonly, itch can also be used transitively, which means it affects a direct object. 抓 搔. zhuā sāo *抓搔* | 抓搔* | *抓搔. to rub or scrape lightly with the finger-nails or claws to relieve itching.
