Microdialysis and SPECT measurements of amphetamine‐induced dopamine release in nonhuman primates
The competition between endogenous transmitters and radiolabeled ligands for in vivo binding to neuroreceptors might provide a method to measure endogenous transmitter release in the living humanExpand
Serotonin-mediated increase in prefrontal cortex dopamine release: pharmacological characterization.
Interactions between serotonin (5-HT) and dopamine (DA) neuronal systems in the prefrontal cortex (PFC) may be important in the pathophysiology of cognitive disorders such as schizophrenia. We haveExpand

Using a model of recreational cocaine consumption, we have determined in four rhesus monkeys the impact of self-administered cocaine on mesolimbic and sensorimotor striatal dopaminergicExpand
Cocaethylene: a neuropharmacologically active metabolite associated with concurrent cocaine-ethanol ingestion.
High concentrations of cocaethylene (EC), the ethyl ester of benzoylecgonine, were measured in the blood of individuals who had concurrently used cocaine and ethanol. Since the powerful reinforcingExpand
Effect of ethanol on extracellular 5-HT and glutamate in the nucleus accumbens and prefrontal cortex: Comparison between the Lewis and Fischer 344 rat strains
The present study investigated the impact of systemic (i.p.) ethanol administration on extracellular levels of serotonin and glutamate in the prefrontal cortex and the nucleus accumbens in Lewis andExpand
Cocaine and Cocaethylene: Microdialysis Comparison of Brain Drug Levels and Effects on Dopamine and Serotonin
Abstract: Cocaethylene is a pharmacologically active metabolite resulting from concurrent cocaine and ethanol consumption. The effects of cocaine and cocaethylene on extracellular levels of dopamineExpand
Impact of Self-Administered Cocaine and Cocaine Cues on Extracellular Dopamine in Mesolimbic and Sensorimotor Striatum in Rhesus Monkeys
Studies were conducted to determine the impact of self-administered cocaine on extracellular striatal dopamine in four rhesus monkeys. The extent to which external cue conditioning contributed to theExpand
Psychostimulant Abuse and Neuroinflammation: Emerging Evidence of Their Interconnection
During the past two decades, there has been a tremendous expansion of knowledge regarding the neurobiological effects of substance abuse and how these effects impact behavior. At the same time, thereExpand
Cognitive impact of genetic variation of the serotonin transporter in primates is associated with differences in brain morphology rather than serotonin neurotransmission
A powerful convergence of genetics, neuroimaging and epidemiological research has identified the biological pathways mediating individual differences in complex behavioral processes and the relatedExpand
Mesocortical dopamine neurons: High basal firing frequency predicts tyrosine dependence of dopamine synthesis
Mesocortical dopamine (DA) neurons projecting to the prefrontal and cingulate cortices possess a faster basal firing rate and exhibit more bursting than other midbrain DA neurons. Thus, we examinedExpand
