Itch is an unpleasant sensation accompanied by the urge to scratch. The act of scratching not only alleviates itch but also activates reward circuitry, inducing a pleasurable that can perpetuate further scratching. Therefore, be characterized as both goal-directed behavior and reward-motivated behavior. As key hub for sensorymotor integration information processing in tasks, specific role posterior parietal cortex (PPC) modulating remains elucidated. Using immunofluorescence calcium-signal fiber photometric recordings, we found neurons association (PtA), subregion PPC, were activated during acute itch. Pharmacogenetic experiments demonstrated nonselective inhibition PtA selective pyramidal neuron activity reduced experimental itch-scratching induced subcutaneous injections 5-HT compound 48/80. projects dorsal striatum (DS), critical component brain's this pathway diminished study first time may involved regulation histaminergic nonhistaminergic through projections DS.
