摘要: Emily Dickinson declared: 'After great pain, a formal feeling comes'. This begins when sensory neurons are activated by noxious stimuli, such as stepping on tack. Recently, Seymour Benzer's group identified in Drosophila larvae that mediate aversive responses to heat and mechanical stimuli. Thresholds for behavioral nerve elevated mutations the painless gene, which encodes TRP ion channel protein. Painless thus joins an elite of TRPs implicated transduction insects, nematodes, mammals fish.
