Juvenile exposure to methylphenidate and guanfacine in rats: effects on early delay discounting and later cocaine-taking behavior.

abstract：:The phase of highly focused, repetitive behavior (stereotypy) induced by amphetamine in rats emerges after an initial period of locomotor activation. To assess the neuronal correlates of this behavioral transition, single-unit activity was recorded from the dorsal striatum of awake, unrestrained rats. Units were first...
