This article reviews the evaluation and optimization of the preprocessing steps for blood-
oxygenation-level-dependent (BOLD) functional magnetic resonance imaging (fMRI). This …

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 …

Our goal in the current report was to design a new functional magnetic resonance imaging
(fMRI) task to probe the role of the anterior cingulate cortex (ACC) and orbitofrontal cortex …

IEEE Engineering in Medicine and Biology Magazine focuses on modern methods for the
analysis of data from functional magnetic resonance imaging (fMRI) studies. Accordingly, the …

Objective: This study attempted to examine the brain's sensitivity to monetary rewards of
different magnitudes in cocaine abusers and to study its association with motivation and self …

Cocaine, through its activation of dopamine (DA) signaling, usurps pathways that process
natural rewards. However, the extent to which there is overlap between the networks that …

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 …

Anterior cingulate cortex (ACC) hypoactivations during cognitive processing characterize
drug addicted individuals as compared with healthy controls. However, impaired behavioral …

Attention and memory deficits have been reported in heavy marijuana users, but these
effects may be reversible after prolonged abstinence. It remains unclear whether the …
