Environment makes amphetamine-induced dopamine release in the nucleus accumbens totally impulse-dependent

Research output: Contribution to journalArticle

Abstract

Environmental condition such as food restriction has been shown to produce sensitization to the stimulant and rewarding effects of amphetamine in the low responsive DBA/2J genotype. Here, we report that food-restricted DBA/2J mice lose the impulse-independent component of psychostimulant-induced dopamine release in the nucleus accumbens that is replaced totally by impulse-dependent dopamine release. These results indicate for the first time that the crucial effect of environment-induced sensitization is a dramatic increase of the impulse dependent component.
