A watershed model of individual differences in fluid intelligence
(Neuropsychologia, 2016-10) -
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 ... -
Age mediation of frontoparietal activation during visual feature search.
(Neuroimage, 2014-11-15)Activation of frontal and parietal brain regions is associated with attentional control during visual search. We used fMRI to characterize age-related differences in frontoparietal activation in a highly efficient feature ... -
Age-related sensitivity to task-related modulation of language-processing networks
(Neuropsychologia, 2014-10) -
An fMRI investigation of posttraumatic flashbacks
(Brain and Cognition, 2013-02) -
Application of long-interval paired-pulse transcranial magnetic stimulation to motion-sensitive visual cortex does not lead to changes in motion discrimination.
(Neuroscience letters, 2020-05-12)The perception of visual motion is dependent on a set of occipitotemporal regions that are readily accessible to neuromodulation. The current study tested if paired-pulse Transcranial Magnetic Stimulation (ppTMS) could modulate ... -
Cerebral white matter connectivity, cognition, and age-related macular degeneration.
(NeuroImage. Clinical, 2021-02-23)Age-related macular degeneration (AMD) is a common retina disease associated with cognitive impairment in older adults. The mechanism(s) that account for the link between AMD and cognitive decline remain unclear. Here we ... -
Cooperative contributions of structural and functional connectivity to successful memory in aging.
(Network neuroscience (Cambridge, Mass.), 2019-01)Understanding the precise relation between functional connectivity and structural (white matter) connectivity and how these relationships account for cognitive changes in older adults are major challenges for neuroscience. ... -
Cross-hemispheric collaboration and segregation associated with task difficulty as revealed by structural and functional connectivity.
(J Neurosci, 2015-05-27)Although it is known that brain regions in one hemisphere may interact very closely with their corresponding contralateral regions (collaboration) or operate relatively independent of them (segregation), the specific brain ... -
Distinct aspects of frontal lobe structure mediate age-related differences in fluid intelligence and multitasking
(Nature Communications, 2014-12-18) -
Effects of online repetitive transcranial magnetic stimulation (rTMS) on cognitive processing: A meta-analysis and recommendations for future studies.
(Neuroscience and biobehavioral reviews, 2019-12)Online repetitive transcranial magnetic stimulation (rTMS), applied while subjects are performing a task, is widely used to disrupt brain regions underlying cognition. However, online rTMS has also induced "paradoxical ... -
Examining the Role of Lateral Parietal Cortex in Emotional Distancing Using TMS.
(Cognitive, affective & behavioral neuroscience, 2020-10)We recently proposed a neurocognitive model of distancing-an emotion regulation tactic-with a focus on the lateral parietal cortex. Although this brain area has been implicated in both cognitive control and self-projection ... -
Intensity- and timing-dependent modulation of motion perception with transcranial magnetic stimulation of visual cortex.
(Neuropsychologia, 2020-10)Despite the widespread use of transcranial magnetic stimulation (TMS) in research and clinical care, the dose-response relations and neurophysiological correlates of modulatory effects remain relatively unexplored. To fill ... -
Inter-Parietal White Matter Development Predicts Numerical Performance in Young Children.
(Learn Individ Differ, 2011-12)In an effort to understand the role of interhemispheric transfer in numerical development, we investigated the relationship between children's developing knowledge of numbers and the integrity of their white matter connections ... -
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 ... -
Multiple determinants of lifespan memory differences
(Scientific Reports, 2016-09-07)© The Author(s) 2016.Memory problems are among the most common complaints as people grow older. Using structural equation modeling of commensurate scores of anterograde memory from a large (N = 315), population-derived sample ... -
Network-level dynamics underlying a combined rTMS and psychotherapy treatment for major depressive disorder: An exploratory network analysis.
(International journal of clinical and health psychology : IJCHP, 2023-10)<h4>Background</h4>Despite the growing use of repetitive transcranial magnetic stimulation (rTMS) as a treatment for depression, there is a limited understanding of the mechanisms of action and how potential treatment-related ... -
Resting-state networks do not determine cognitive function networks: a commentary on Campbell and Schacter (2016)
(Language, Cognition and Neuroscience, 2016-11-08) -
Robust resilience of the frontotemporal syntax system to aging
(Journal of Neuroscience, 2016-05-11)© 2016 the authors.Brain function is thought to become less specialized with age. However, this view is largely based on findings of increased activation during tasks that fail to separate task-related processes (e.g., attention, ... -
Site-Specific Effects of Online rTMS during a Working Memory Task in Healthy Older Adults.
(Brain sciences, 2020-04-27)The process of manipulating information within working memory is central to many cognitive functions, but also declines rapidly in old age. Improving this process could markedly enhance the health-span in older adults. The ...
