Intravenous ethanol/cocaine self-administration initiates high intake of intravenous ethanol alone.

Chronic D1 agonist and ethanol coadministration facilitate ethanol-mediated behaviors.

Nucleus accumbens and medial prefrontal cortex dopaminergic response to self-administered cocaine in naive rats.

Dopamine mechanisms and cocaine reward.

Age-dependent (+)MDMA-mediated neurotoxicity in mice.

Prefrontal cortex D1 modulation of the reinforcing properties of cocaine.

Experience-dependent changes in temperature and behavioral activity induced by MDMA.

Comparing nucleus accumbens and dorsal striatal dopamine responses to self-administered cocaine in naïve rats.

Increased accumbens Cdk5 expression in rats after short-access to self-administered cocaine, but not after long-access sessions.

Experience-dependent effects of cocaine self-administration/conditioning on prefrontal and accumbens dopamine responses.

The recreational drug ecstasy disrupts the hypothalamic-pituitary-gonadal reproductive axis in adult male rats.

Certain or uncertain cocaine expectations influence accumbens dopamine responses to self-administered cocaine and non-rewarded operant behavior.

Diazepam alters cocaine self-administration, but not cocaine-stimulated locomotion or nucleus accumbens dopamine.

Auditory stimuli enhance MDMA-conditioned reward and MDMA-induced nucleus accumbens dopamine, serotonin and locomotor responses.

Repeated intravenous amphetamine exposure: rapid and persistent sensitization of 50-kHz ultrasonic trill calls in rats.

Behavioral, thermal and neurochemical effects of acute and chronic 3,4-methylenedioxymethamphetamine ("Ecstasy") self-administration.

Repeated intravenous cocaine experience: development and escalation of pre-drug anticipatory 50-kHz ultrasonic vocalizations in rats.

Cocaine deprivation effect: cue abstinence over weekends boosts anticipatory 50-kHz ultrasonic vocalizations in rats.

Heat increases MDMA-enhanced NAcc 5-HT and body temperature, but not MDMA self-administration.

The missing variable: ultrasonic vocalizations reveal hidden sensitization and tolerance-like effects during long-term cocaine administration.
