A case of frontal neuropsychological and neuroimaging signs following multiple primary-blast exposure.
(Neurocase, 2012-06)Blast-related traumatic brain injury (TBI) from the Afghanistan and Iraq wars represents a significant medical concern for troops and veterans. To better understand the consequences of primary-blast injury in humans, we ... -
A neurophysiological study into the foundations of tonal harmony.
(Neuroreport, 2009-02-18)Our findings provide magnetoencephalographic evidence that the mismatch-negativity response to two-note chords (dyads) is modulated by a combination of abstract cognitive differences and lower-level differences in the auditory ... -
Adult age differences in functional connectivity during executive control.
(Neuroimage, 2010-08-15)Task switching requires executive control processes that undergo age-related decline. Previous neuroimaging studies have identified age-related differences in brain activation associated with global switching effects (dual-task ... -
Aerobic exercise and neurocognitive performance: a meta-analytic review of randomized controlled trials.
(Psychosom Med, 2010-04)OBJECTIVES: To assess the effects of aerobic exercise training on neurocognitive performance. Although the effects of exercise on neurocognition have been the subject of several previous reviews and meta-analyses, they have ... -
Age-related preservation of top-down control over distraction in visual search.
(Experimental aging research, 2010-07)Visual search studies have demonstrated that older adults can have preserved or even increased top-down control over distraction. However, the results are mixed as to the extent of this age-related preservation. The present ... -
Brain connectivity and visual attention.
(Brain connectivity, 2013-01)Emerging hypotheses suggest that efficient cognitive functioning requires the integration of separate, but interconnected cortical networks in the brain. Although task-related measures of brain activity suggest ... -
Cocaine dependence does not contribute substantially to white matter abnormalities in HIV infection.
(Journal of neurovirology, 2017-06)This study investigated the association of HIV infection and cocaine dependence with cerebral white matter integrity using diffusion tensor imaging (DTI). One hundred thirty-five participants stratified by HIV and cocaine ... -
Cognitive and neural contributors to emotion regulation in aging.
(Social cognitive and affective neuroscience, 2011-04)Older adults, compared to younger adults, focus on emotional well-being. While the lifespan trajectory of emotional processing and its regulation has been characterized behaviorally, few studies have investigated the underlying ... -
Demographic, maltreatment, and neurobiological correlates of PTSD symptoms in children and adolescents.
(J Pediatr Psychol, 2010-06)OBJECTIVE: To examine the relationships of demographic, maltreatment, neurostructural and neuropsychological measures with total posttraumatic stress disorder (PTSD) symptoms. METHODS: Participants included 216 children ... -
Dose of early intervention treatment during children's first 36 months of life is associated with developmental outcomes: an observational cohort study in three low/low-middle income countries.
(BMC pediatrics, 2014-10-25)The positive effects of early developmental intervention (EDI) on early child development have been reported in numerous controlled trials in a variety of countries. An important aspect to determining the efficacy of EDI ... -
Editorial: choice studies in transition.

Effects of adult age and blood pressure on executive function and speed of processing.
(Experimental aging research, 2010-04)Previous research has established that the effects of chronically increased blood pressure (BP) on cognition interact with adult age, but the relevant cognitive processes are not well defined. In this cross-sectional study, ... -
Effects of chronic mild traumatic brain injury on white matter integrity in Iraq and Afghanistan war veterans.
(Human Brain Mapping, 2013-11)Mild traumatic brain injury (TBI) is a common source of morbidity from the wars in Iraq and Afghanistan. With no overt lesions on structural MRI, diagnosis of chronic mild TBI in military veterans relies on obtaining an ... -
Effects of task instruction on autobiographical memory specificity in young and older adults.
(Memory, 2014)Older adults tend to retrieve autobiographical information that is overly general (i.e., not restricted to a single event, termed the overgenerality effect) relative to young adults' specific memories. A vast majority of ... -
Effects of the dietary approaches to stop hypertension diet, exercise, and caloric restriction on neurocognition in overweight adults with high blood pressure.
(Hypertension, 2010-06)High blood pressure increases the risks of stroke, dementia, and neurocognitive dysfunction. Although aerobic exercise and dietary modifications have been shown to reduce blood pressure, no randomized trials have examined ... -
Entorhinal cortex volume in older adults: reliability and validity considerations for three published measurement protocols.
(J Int Neuropsychol Soc, 2010-09)Measuring the entorhinal cortex (ERC) is challenging due to lateral border discrimination from the perirhinal cortex. From a sample of 39 nondemented older adults who completed volumetric image scans and verbal memory indices, ... -
Functional neuroimaging of emotionally intense autobiographical memories in post-traumatic stress disorder.
(J Psychiatr Res, 2011-05)Post-traumatic stress disorder (PTSD) affects regions that support autobiographical memory (AM) retrieval, such as the hippocampus, amygdala and ventral medial prefrontal cortex (PFC). However, it is not well understood ... -
Global versus tract-specific components of cerebral white matter integrity: relation to adult age and perceptual-motor speed.
(Brain structure & function, 2015-09)Although age-related differences in white matter have been well documented, the degree to which regional, tract-specific effects can be distinguished from global, brain-general effects is not yet clear. Similarly, the manner ... -
H.M.'s personal crossword puzzles: understanding memory and language.
(Memory, 2008-02)The amnesic patient H.M. has been solving crossword puzzles nearly all his life. Here, we analysed the linguistic content of 277 of H.M.'s crossword-puzzle solutions. H.M. did not have any unusual difficulties with ... -
Less wiring, more firing: low-performing older adults compensate for impaired white matter with greater neural activity.
(Cereb Cortex, 2015-04)The reliable neuroimaging finding that older adults often show greater activity (over-recruitment) than younger adults is typically attributed to compensation. Yet, the neural mechanisms of over-recruitment in older adults ...
