Role of dopamine D 1 -like and D 2 -like receptors in the activation of ingestive behaviour in thirsty rats licking for water

ConclusionThe results support the suggestion that D1 receptors are involved in behavioural activation and D2 receptors are involved in a related evaluation process. Within the framework of the proposed hypothesis, the increased burst size after D1-like receptor blockade might be interpreted as a pro-hedonic effect consequent to the increased cost of the activation of the licking response.
