Effect of handedness on fMRI activation in the medial temporal lobe during an auditory verbal memory task
(Wiley Subscription Services, Inc., A Wiley Company, 2009-04)
Several studies have shown marked differences in the neural localization of language functions in the brains of left-handed individuals when compared with right-handers. Previous experiments involving functional lateralization ...
Brain correlates of phasic autonomic response to acupuncture stimulation: An event‐related fMRI study
(Beijing Foreign Languages PressWiley Periodicals, Inc., 2013-10)
Vestibular brain changes within 70 days of head down bed rest
(Wiley Periodicals, Inc.Oxford University Press, 2018-07)
Headâ downâ tilt bed rest (HDBR) is frequently utilized as a spaceflight analog research environment to study the effects of axial body unloading and fluid shifts that are associated with spaceflight in the absence of ...
Development and evaluation of a multimodal marker of major depressive disorder
(John Wiley & Sons, Inc., 2018-11)
This study aimed to identify biomarkers of major depressive disorder (MDD), by relating neuroimage‐derived measures to binary (MDD/control), ordinal (severe MDD/mild MDD/control), or continuous (depression severity) outcomes. ...
Detecting low-frequency functional connectivity in fMRI using a self-organizing map (SOM) algorithm
(Wiley Subscription Services, Inc., A Wiley Company, 2003-12)
Low-frequency oscillations (<0.08 Hz) have been detected in functional MRI studies, and appear to be synchronized between functionally related areas. A current challenge is to detect these patterns without using an external ...
The neurosteroids allopregnanolone and dehydroepiandrosterone modulate resting‐state amygdala connectivity
(University of IowaWiley Periodicals, Inc., 2014-07)
The neurosteroids allopregnanolone and dehydroepiandrosterone (DHEA) are integral components of the stress response and exert positive modulatory effects on emotion in both human and animal studies. Although these ...
Using fMRI to dissociate sensory encoding from cognitive evaluation of heat pain intensity
(Wiley Subscription Services, Inc., A Wiley Company, 2006-09)
Neuroimaging studies of painful stimuli in humans have identified a network of brain regions that is more extensive than identified previously in electrophysiological and anatomical studies of nociceptive pathways. This ...
Neural predictors of sensorimotor adaptation rate and savings
(Wiley Periodicals, Inc., 2018-04)
In this study, we investigate whether individual variability in the rate of visuomotor adaptation and multiday savings is associated with differences in regional gray matter volume and restingâ state functional connectivity. ...
Reduced executive and default network functional connectivity in cigarette smokers
(American Physiological SocietyWiley Periodicals, Inc., 2015-03)
Altered functional connectivity has been associated with acute and chronic nicotine use. Connectivity alterations, specifically in the right and left executive control networks (RECN/LECN) and the default mode network ...
Breakdown in the temporal and spatial organization of spontaneous brain activity during general anesthesia
(Wiley Periodicals, Inc.Oxford University Press, 2018-05)
Which temporal features that can characterize different brain states (i.e., consciousness or unconsciousness) is a fundamental question in the neuroscience of consciousness. Using resting‐state functional magnetic resonance ...
