Possible role of dopamine D1-like and D2-like receptors in behavioural activation and “contingent” reward evaluation in sodium-replete and sodium-depleted rats licking for NaCl solutions

Based on the different effects of the dopamine D1-like and D2-like receptor antagonists SCH 23390 and raclopride on the measures of licking microstructure in rats, we suggested that the level of activation of reward-associated responses depends on dopamine D1-like receptor stimulation, and is update...
