A powerful convergence of genetics, neuroimaging and epidemiological research has identified the biological pathways mediating individual differences in complex behavioral processes and the related risk for disease. Orthologous genetic variation in non-human primates (NHPs) represents a unique opportunity to characterize the detailed molecular and cellular(More)
Cocaine users display a wide range of cognitive impairments. Because treatment outcome is dependent on baseline cognitive ability, it is clinically important to understand the underlying neurobiology of these deficits. Therefore, it is crucial to determine whether cocaine exposure by itself is an etiological factor and, if so, to determine the overall(More)
Cocaine use is associated with cognitive impairment which impacts treatment outcome. A clearer understanding of those deficits, and whether particular environments exacerbate them, is needed. This study evaluated whether previously observed domain-specific cognitive deficits persisted following a 3-month cessation from chronic cocaine self-administration,(More)
Differences in brain function in cocaine users can occur even when frank deficits are not apparent, indicating neuroadaptive consequences of use. Using monkeys to investigate altered metabolic activity following chronic cocaine self-administration allows an assessment of altered function due to cocaine use, without confounding pre-existing differences or(More)
Pacemaker infections can be difficult to diagnose, especially when they present with non-specific symptoms and signs a long time after insertion of the device. Unidentified or partially treated low-grade chronic sepsis can result in multisystem disease processes with significant mortality and morbidity. Therefore, a high index of suspicion is required to(More)
