The dynamics of proactive and reactive cognitive control processes in the human brain.
(J Cogn Neurosci, 2014-05)
In this study, we leveraged the high temporal resolution of EEG to examine the neural mechanisms underlying the flexible regulation of cognitive control that unfolds over different timescales. We measured behavioral and ...
Differentiating sensitivity of post-stimulus undershoot under diffusion weighting: implication of vascular and neuronal hierarchy.
(PLoS One, 2008-08-13)
The widely used blood oxygenation level dependent (BOLD) signal during brain activation, as measured in typical fMRI methods, is composed of several distinct phases, the last of which, and perhaps the least understood, is ...
Fear learning circuitry is biased toward generalization of fear associations in posttraumatic stress disorder.
(Transl Psychiatry, 2015-12-15)
Fear conditioning is an established model for investigating posttraumatic stress disorder (PTSD). However, symptom triggers may vaguely resemble the initial traumatic event, differing on a variety of sensory and affective ...
The exon junction complex component Magoh controls brain size by regulating neural stem cell division.
(Nat Neurosci, 2010-05)
Brain structure and size require precise division of neural stem cells (NSCs), which self-renew and generate intermediate neural progenitors (INPs) and neurons. The factors that regulate NSCs remain poorly understood, and ...
The PsychENCODE project.
(Nat Neurosci, 2015-12)
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 ...
Rapid modulation of sensory processing induced by stimulus conflict.
(J Cogn Neurosci, 2011-09)
Humans are constantly confronted with environmental stimuli that conflict with task goals and can interfere with successful behavior. Prevailing theories propose the existence of cognitive control mechanisms that can suppress ...
Core and region-enriched networks of behaviorally regulated genes and the singing genome.
Songbirds represent an important model organism for elucidating molecular mechanisms that link genes with complex behaviors, in part because they have discrete vocal learning circuits that have parallels with those that ...
The role of stimulus salience and attentional capture across the neural hierarchy in a stop-signal task.
(PLoS One, 2011)
Inhibitory motor control is a core function of cognitive control. Evidence from diverse experimental approaches has linked this function to a mostly right-lateralized network of cortical and subcortical areas, wherein a ...
Differential developmental trajectories of magnetic susceptibility in human brain gray and white matter over the lifespan.
(Hum Brain Mapp, 2014-06)
As indicated by several recent studies, magnetic susceptibility of the brain is influenced mainly by myelin in the white matter and by iron deposits in the deep nuclei. Myelination and iron deposition in the brain evolve ...
