Decreased brain dopaminergic transporters in HIV-associated dementia patients (2004)
Wang, Gene-Jack, Chang, Linda, Volkow, Nora D., Telang, Frank, Logan, Jean, Ernst, Thomas, ...
Summary HIV has a propensity to invade subcortical regions of the brain, which may lead to a subcortical dementia termed HIV-cognitive motor complex. Therefore, we aimed to assess whether dopamine...

Brain monoamine oxidase A inhibition in cigarette smokers
Fowler, Joanna S., Volkow, Nora D., Wang, Gene-Jack, Pappas, Naomi, Logan, Jean, Shea, Colleen, ...
Several studies have documented a strong association between smoking and depression. Because cigarette smoke has been reported to inhibit monoamine oxidase (MAO) A in vitro and in animals and because...
Low monoamine oxidase B in peripheral organs in smokers
Fowler, Joanna S., Logan, Jean, Wang, Gene-Jack, Volkow, Nora D., Telang, Frank, Zhu, Wei, ...
One of the major mechanisms for terminating the actions of catecholamines and vasoactive dietary amines is oxidation by monoamine oxidase (MAO). Smokers have been shown to have reduced levels of...
Goldstein, Rita Z., Leskovjan, Andreana C., Hoff, Anne L., Hitzemann, Robert, Bashan, Francine, Khalsa, Sahib Singh, ...
We used exploratory and confirmatory statistical approaches to study the severity of neuropsychological (NP) impairment in 42 crack/cocaine addicted subjects and in 112 comparison subjects (40...

Drug addiction is characterized by a set of recurring processes (intoxication, withdrawal, craving) that lead to the relapsing nature of the disorder. We have used positron emission tomography to...
The orbitofrontal cortex in methamphetamine addiction: involvement in fear
Goldstein, Rita Z., Volkow, Nora D., Chang, Linda, Wang, Gene-Jack, Fowler, Joanna S., Depue, Richard A., ...
We used Tellegen’s Multidimensional Personality Questionnaire (MPQ) harm avoidance (fear) scale and the constraint superfactor as personality measures of inhibitory control and examined their...
Addiction changes orbitofrontal gyrus function: involvement in response inhibition
Goldstein, Rita Z., Volkow, Nora D., Wang, Gene-Jack, Fowler, Joanna S., Rajaram, Suparna
We used the Stroop task as a measure of the ability to inhibit a prepotent response tendency and examined its association with relative glucose metabolism in selected prefrontal brain regions in...
Anger and depression in cocaine addiction: association with the orbitofrontal cortex
Goldstein, Rita Z., Alia-Klein, Nelly, Leskovjan, Andreana C., Fowler, Joanna S., Wang, Gene-Jack, Gur, Ruben C., ...
The high prevalence of anger, impulsivity and violence in cocaine addiction implicates chronic cocaine use in the compromise of higher-order inhibitory control neurocognitive processes. We used the...

The neurobiological mechanisms underlying overeating in obesity are not understood. Here, we assessed the neurobiological responses to an Implantable Gastric Stimulator (IGS), which induces stomach...
Methylphenidate Decreased the Amount of Glucose Needed by the Brain to Perform a Cognitive Task
Volkow, Nora D., Fowler, Joanna S., Wang, Gene-Jack, Telang, Frank, Logan, Jean, Wong, Christopher, ...
The use of stimulants (methylphenidate and amphetamine) as cognitive enhancers by the general public is increasing and is controversial. It is still unclear how they work or why they improve...
