Xenon and sevoflurane provide analgesia during labor and fetal brain protection in a perinatal rat model of hypoxia-ischemia.
(PloS one, 2012-01)
It is not possible to identify all pregnancies at risk of neonatal hypoxic-ischemic
encephalopathy (HIE). Many women use some form of analgesia during childbirth and
some anesthetic agents have been shown to be neuroprotective ...
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 ...
The time course of segmentation and cue-selectivity in the human visual cortex.
(PLoS One, 2012)
Texture discontinuities are a fundamental cue by which the visual system segments
objects from their background. The neural mechanisms supporting texture-based segmentation
are therefore critical to visual perception and ...
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 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 ...
The neural dynamics of stimulus and response conflict processing as a function of response complexity and task demands.
(Neuropsychologia, 2016-04)
Both stimulus and response conflict can disrupt behavior by slowing response times
and decreasing accuracy. Although several neural activations have been associated
with conflict processing, it is unclear how specific any ...
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 ...
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 ...
