Pentylenetetrazol-kindling modulates stimulated dopamine release in the nucleus accumbens of rats
Pharmacol Biochem Behav.
2000 Jun.
Abstract
Kindling-induced activation of dopaminergic neurones in the nucleus accumbens in pentylenetetrazol (PTZ)-kindled rats was studied using microdialysis. Dopamine (DA) release after PTZ challenge was measured: (1) two weeks and (2) ten weeks after kindling completion and (3) two weeks after a kindling procedure with diazepam (DZP) treatment. In (1) a significant increase in DA concentration was found after PTZ challenge and this increase was still evident 10 weeks after kindling completion (2). Coadministration of DZP in the course of kindling development inhibited the increase in sensitivity of the accumbens dopaminergic system (3).
