Rats shifted from 4% to 32% sucrose displayed successive negative contrast by initiating significantly fewer bouts of licking than control rats maintained on 4% sucrose. No significant increase in dopamine (DA) efflux in the nucleus accumbens (NAc) was observed during consumption of 4% sucrose by rats shifted from 32%. In contrast, consumption of 4% sucrose by control rats was accompanied by a significant increase in DA efflux in the NAc, which remained elevated 10 min postconsumption. These… CONTINUE READING
