| Research Abstract |
In the present study, we examined the role of pain-induced dopamine release within the nucleus accumbens in pain-induced aversion. A significant increase in the dopamine level was observed after the formalin injection only within the rostral part of the nucleus accumbens shell but not within the caudal part. The conditioned place aversion (CPA) induced by the i.pl. formalin injection was reversed by the microinjection of dopamine D2 antagonist into the rostral part of the nucleus accumbens shell. On the other hand, the microinjection of dopamine D2 agonist into the same region did not induce the CPA.
