The concept of reserve has been proposed to account for the disjunction between the
degree of brain damage and its clinical outcome. This paper attempts to produce a coherent …

Advances in the treatment of the human immunodeficiency virus (HIV) have dramatically
improved survival rates over the past 10 years, but HIV-associated neurocognitive disorders …

Approximately 40 million people worldwide are infected with human immunodeficiency virus
(HIV). Despite HIV's known propensity to infect the CNS and cause neurological disease …

The ultimate goal of brain connectivity studies is to propose, test, modify, and compare
certain directional brain pathways. Path analysis or structural equation modeling (SEM) is an …

Human immunodeficiency virus-type 1 (HIV-l) infection is the most common preventable and
treatable cause of neurocognitive impairment in individuals under age 50 years. Although …

Cerebral atrophy is a well-described, but poorly understood complication of human
immunodeficiency virus (HIV) infection. Despite reduced prevalence of HIV-associated …

Objective: Resting-state functional connectivity MRI (rs-fcMRI) may provide insight into the
neurophysiology of HIV and aging. Methods: In this cross-sectional study, we used rs-fcMRI …

Objective: To evaluate the hypothesis that educational attainment, a marker of cognitive
reserve, is a predictor of disability-free recovery (DFR) after moderate to severe traumatic …

Here, we assessed the effects of sleep deprivation (SD) on brain activation and performance
to a parametric visual attention task. Fourteen healthy subjects underwent functional …

This parametric functional magnetic resonance imaging (fMRI) study investigates the
balance of negative and positive fMRI signals in the brain. A set of visual attention (VA) and …
