Neural circuitry underlying sustained attention in healthy adolescents and in ADHD symptomatology (2017)
Journal Article

Moment-to-moment reaction time variability on tasks of attention, often quantified by intra-individual response variability (IRV), provides a good indication of the degree to which an individual is vulnerable to lapses in sustained attention. Increa... Read More about Neural circuitry underlying sustained attention in healthy adolescents and in ADHD symptomatology.

The z-spectrum from human blood at 7T (2017)
Journal Article

Chemical Exchange Saturation Transfer (CEST) has been used to assess healthy and pathological tissue in both animals and humans. However, the CEST signal from blood has not been fully assessed. This paper presents the CEST and nuclear Overhauser enha... Read More about The z-spectrum from human blood at 7T.

Seven-Tesla magnetization transfer imaging to detect multiple sclerosis white matter lesions (2017)
Journal Article

BACKGROUND AND PURPOSE: Fluid-attenuated inversion recovery (FLAIR) imaging at 3 Tesla (T) field strength is the most sensitive modality for detecting white matter lesions in multiple sclerosis. While 7T FLAIR is effective in detecting cortical lesio... Read More about Seven-Tesla magnetization transfer imaging to detect multiple sclerosis white matter lesions.

Overdominant effect of a CHRNA4 polymorphism on cingulo-opercular network activity and cognitive control (2017)
Journal Article

The nicotinic system plays an important role in cognitive control, and is implicated in several neuropsychiatric conditions. Yet, the contributions of genetic variability in this system to individuals' cognitive control abilities are poorly understoo...

MRI assessment of the postprandial gastrointestinal motility and peptide response in healthy humans (2017)
Journal Article

Background: Feeding triggers inter-related gastrointestinal (GI) motor, peptide and appetite responses. These are rarely studied together due to methodological limitations. Recent MRI advances allow pan-intestinal, non-invasive assessment of motility... Read More about MRI assessment of the postprandial gastrointestinal motility and peptide response in healthy humans.

Decoding fMRI events in sensorimotor motor network using sparse paradigm free mapping and activation likelihood estimates: Decoding fMRI Events in SMN (2017)
Journal Article

Most functional MRI (fMRI) studies map task-driven brain activity using a block or event-related paradigm. Sparse paradigm free mapping (SPFM) can detect the onset and spatial distribution of BOLD events in the brain without prior timing information,...

Magnetic resonance imaging quantification of fasted state colonic liquid pockets in healthy humans (2017)
Journal Article

The rate and extent of drug dissolution and absorption from solid oral dosage forms is highly dependent on the volume of liquid in the gastrointestinal tract (GIT). However, little is known about the time course of GIT liquid volumes after drinking a...

Presence of time-dependent diffusion in the brachial plexus (2017)
Journal Article

© 2017 International Society for Magnetic Resonance in Medicine Purpose: This work describes the development of a method to measure the variation of apparent diffusion coefficient (ADC) with diffusion time (Δ) in the brachial plexus, as a potential m... Read More about Presence of time-dependent diffusion in the brachial plexus.

Psychosocial stress and brain function in adolescent psychopathology (2017)
Journal Article

Objective: To explore how conduct, hyperactivity/inattention, and emotional symptoms are associated with neural reactivity to social-emotional stimuli, and the extent to which psychosocial stress modulates these relationships. Method: Participants w... Read More about Psychosocial stress and brain function in adolescent psychopathology.

Assessment of motion of colonic contents in the human colon using MRI tagging (2017)
Journal Article

Background We have previously reported a non-invasive, semi-automated technique to assess motility of the wall of the ascending colon (AC) using Magnetic Resonance Imaging. This study investigated the feasibility of using a tagged MRI technique to vi... Read More about Assessment of motion of colonic contents in the human colon using MRI tagging.

Functional neuroimaging predictors of self-reported psychotic symptoms in adolescents (2017)
Journal Article

OBJECTIVE: This study aimed to investigate the neural correlates of psychotic-like experiences in youth on measures of inhibitory control, reward anticipation and emotion processing. A secondary aim was to test whether these neuro-functional correlat... Read More about Functional neuroimaging predictors of self-reported psychotic symptoms in adolescents.

³¹P magnetization transfer magnetic resonance spectroscopy: assessing the activation induced change in cerebral ATP metabolic rates at 3 T (2017)
Journal Article

Purpose: In vivo ³¹P MRS magnetization transfer (MT) provides a direct measure of neuronal activity at the metabolic level. This work aims to use functional ³¹P MRS-MT to investigate the change in cerebral ATP metabolic rates in healthy adults upon r...

Impact of a common genetic variation associated with putamen volume on neural mechanisms of ADHD (2017)
Journal Article

Objective: In a recent genome-wide association study of subcortical brain volumes, we have identified common genetic variation at rs945270 as having the strongest effect on putamen volume, a brain measure linked to familial risk for attentiondeficit/...

ICNIRP statement on diagnostic devices using non-ionizing radiation: existing regulations and potential health risks (2017)
Journal Article

Use of non-ionizing radiation (NIR) for diagnostic purposes allows non-invasive assessment of the structure and function of the human body, and is widely employed in medical care. ICNIRP has published previous statements about the protection of patie...

Abnormal task driven neural oscillations in multiple sclerosis: a visuomotor MEG study (2017)
Journal Article

Multiple sclerosis (MS) is a debilitating disease commonly attributed to degradation of white matter myelin. Symptoms include fatigue, as well as problems associated with vision and movement. Although areas of demyelination in white matter are observ... Read More about Abnormal task driven neural oscillations in multiple sclerosis: a visuomotor MEG study.
