Serotonin depletion led to reward-seeking deficits in rats. (a) A single administration of PCPA was sufficient to significantly reduce serotonin levels in male Wistar Kyoto rats. Values are provided as arbitrary relative units. (b) In the female urine sniffing test, serotonin-depleted rats spent significantly less time sniffing urine, but not water, compared to control animals. Data are mean±S.E.M. (* p<0.05, *** p<0.001).
