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 effects on the neural correlates of autobiographical memory retrieval.
(Neurobiol Aging, 2012-07)Older adults recall less episodically rich autobiographical memories (AM), however, the neural basis of this effect is not clear. Using functional MRI, we examined the effects of age during search and elaboration phases ... -
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 ... -
Brain activity during episodic retrieval of autobiographical and laboratory events: an fMRI study using a novel photo paradigm.
(J Cogn Neurosci, 2004-11)Functional neuroimaging studies of episodic memory retrieval generally measure brain activity while participants remember items encountered in the laboratory ("controlled laboratory condition") or events from their own life ... -
Co-activation of the amygdala, hippocampus and inferior frontal gyrus during autobiographical memory retrieval.
(Neuropsychologia, 2005)Functional MRI was used to investigate the role of medial temporal lobe and inferior frontal lobe regions in autobiographical recall. Prior to scanning, participants generated cue words for 50 autobiographical memories and ... -
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 ... -
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 ... -
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 ... -
Mental hoop diaries: emotional memories of a college basketball game in rival fans.
(J Neurosci, 2010-02-10)The rivalry between the men's basketball teams of Duke University and the University of North Carolina-Chapel Hill (UNC) is one of the most storied traditions in college sports. A subculture of students at each university ... -
Neural correlates of emotional processing in depression: changes with cognitive behavioral therapy and predictors of treatment response.
(J Psychiatr Res, 2011-05)Major depressive disorder (MDD) is characterized by the presence of disturbances in emotional processing. However, the neural correlates of these alterations, and how they may be affected by therapeutic interventions, remain ... -
Neural mechanisms of context effects on face recognition: automatic binding and context shift decrements.
(J Cogn Neurosci, 2010-11)Although people do not normally try to remember associations between faces and physical contexts, these associations are established automatically, as indicated by the difficulty of recognizing familiar faces in different ... -
Resting-state networks do not determine cognitive function networks: a commentary on Campbell and Schacter (2016)

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 ... -
Task-related changes in degree centrality and local coherence of the posterior cingulate cortex after major cardiac surgery in older adults.
(Hum Brain Mapp, 2017-11-21)OBJECTIVES: Older adults often display postoperative cognitive decline (POCD) after surgery, yet it is unclear to what extent functional connectivity (FC) alterations may underlie these deficits. We examined for postoperative ... -
The architecture of cross-hemispheric communication in the aging brain: linking behavior to functional and structural connectivity.
(Cereb Cortex, 2012-01)Contralateral recruitment remains a controversial phenomenon in both the clinical and normative populations. To investigate the neural correlates of this phenomenon, we explored the tendency for older adults to recruit prefrontal ... -
The INTUIT Study: Investigating Neuroinflammation Underlying Postoperative Cognitive Dysfunction.
(Journal of the American Geriatrics Society, 2019-01-23)BACKGROUND/OBJECTIVES:Every year, up to 40% of the more than 16 million older Americans who undergo anesthesia/surgery develop postoperative cognitive dysfunction (POCD) or delirium. Each of these distinct syndromes is associated ... -
The neural basis of involuntary episodic memories.
(J Cogn Neurosci, 2014-10)Voluntary episodic memories require an intentional memory search, whereas involuntary episodic memories come to mind spontaneously without conscious effort. Cognitive neuroscience has largely focused on voluntary memory, ... -
The short and long of it: neural correlates of temporal-order memory for autobiographical events.
(J Cogn Neurosci, 2008-07)Previous functional neuroimaging studies of temporal-order memory have investigated memory for laboratory stimuli that are causally unrelated and poor in sensory detail. In contrast, the present functional magnetic resonance ...
