Abstract
Rats allowed concurrent access to intravenous heroin and intracranial self-stimulation (ICSS) showed facilitation of ICSS while maintaining stable self-administration of heroin. The facilitatory action of heroin on ICSS was indexed by an increase in response rates and a lowering of intensity thresholds. Both measures showed dose-dependent changes, but only threshold tracking allowed a reliable determination of the time-dependent effect of self-administered heroin on ICSS.
