[Circling behavior produced by the unilateral intra-accumbens injection of dopaminergic agonist and two dopaminergic antagonists in mice].

Unilateral intra-accumbens injection of apomorphine, a dopaminergic agonist, produced circling contralateral to the site of injection in Balb/c mice. Unilateral intra-accumbens injection of haloperidol and metoclopramide, two dopaminergic antagonists, produced ipsilateral circling. These results support the hypothesis that the dopaminergic receptors in the… CONTINUE READING
