ADHD is associated with spatial working memory deficits, thought to be subserved by dysfunction of neural circuits. In this study we aimed to further examine fronto-parietal dysfunction in ADHD by examining brain activation associated with the Raven’s Progressive Matrices task, a visuo-spatial pattern sequencing task involving relational reasoning ...

Recent studies reveal that young carriers of the fragile X premutation are at increased risk for psychiatric conditions, memory problems and executive deficits. Post mortem and structural MRI studies suggest the hippocampus is preferentially affected by the premutation. The current study utilized magnetic resonance imaging (MRI) to explore the rela...

Athletes who fail are susceptible to negative affect (NA) and impaired future performance. Functional magnetic resonance imaging (fMRI) studies have identified prefrontal, anterior cingulate, and limbic activations following negative mood provocation. Little is known about the neural correlates of negative self-reference (SR), especially in athlete...

Presurgical determination of language laterality is an important step for assessing potential risk of dysfunction resulting from brain resection within or near suspected language areas. Image-based functional MRI (fMRI) methods seek to address limitations to the clinical gold-standard technique by offering a safer, less costly, and non-invasive alt...

Previous studies have shown that exposure to early life stress (ELS) is associated with reduced volume of brain regions critical for information processing, memory and emotional function. Further, recent studies from our lab utilizing diffusion tensor imaging (DTI) have found alterations in the microstructural integrity of white matter pathways amo...

Diffusion tensor imaging was used to study the combined effects of HIV-infection and alcoholism (ALC) on corpus callosum (CC) integrity in relation to processes of attentional allocation and conflict resolution assessed by a novel Stroop Match-to-Sample task. We tested 16 ALC, 19 HIV, 20 subjects with combined disorder and 17 controls. In ALC, low ...

To achieve greater understanding of the brain mechanisms underlying nicotine craving in female smokers, we examined the influence of nicotine non-abstinence vs. acute nicotine abstinence on cue-elicited activation of the ventral striatum. Eight female smokers underwent an event-related functional magnetic resonance imaging (fMRI) paradigm presentin...

Recent work regarding the analysis of brain imaging data has focused on examining functional connectivity of the brain. In this paper, we developed and applied a novel framework to examine the modulation of functional connectivity networks during resting state or experimental stimuli. Hierarchical clustering within anatomically parcellated brain re...

The current study investigated normal aging associated differences on hemispheric laterality of sensory responses to nonverbal auditory stimuli using magnetoencephalography. Twelve older and 12 younger adults with normal hearing thresholds participated. The spatial locations, latencies, and strengths of evoked field M50 and M100 were quantified by ...

Sound timbre and sound volume processing are basic auditory discrimination processes relevant for human language abilities. Regarding lateralization effects, the prevailing hypotheses ascribe timbre processing to the right hemisphere (RH). Recent experiments also point to a role of the RH for volume discrimination. We investigated the relevance of ...
