Effects of Noninvasive Cervical Vagal Nerve Stimulation on Cognitive Performance But Not Brain Activation in Healthy Adults

open access: yesNeuromodulation: Technology at the Neural Interface, EarlyView., 2020
Abstract Objectives While preliminary evidence suggests that noninvasive vagal nerve stimulation (nVNS) may enhance cognition, to our knowledge, no study has directly assessed the effects of nVNS on brain function and cognitive performance in healthy individuals.

Resting State fMRI Reveals Diminished Functional Connectivity in a Mouse Model of Amyloidosis [PDF]

open access: yes, 2013
Introduction: Functional connectivity (FC) studies have gained immense popularity in the evaluation of several neurological disorders, such as Alzheimer’s disease (AD). AD is a complex disorder, characterised by several pathological features. The problem

Multimodal MRI and multiomics reveal high‐risk neurophenotype in brain‐gut circuits as therapeutic target for Crohn's disease

open access: yesInterdisciplinary Medicine, EarlyView.
Through a translational framework combining prospective dual‐center clinical cohorts with dextran sulfate sodium‐induced colitis models, this work integrated advanced neuroimaging, multi‐omics and neuromodulation interventions to redefine the high‐risk neurophenotype as a sustained pathogenic driver rather than a mere phenomenon, proposing brain‐gut ...

A Guide to Designing a Memory fMRI Paradigm for Pre-surgical Evaluation in Temporal Lobe Epilepsy

open access: yesFrontiers in Neurology, 2020
There has been increasing interest in the clinical and experimental use of memory functional Magnetic Resonance Imaging (fMRI). The 2017 American Academy of Neurology practice guidelines on the use of pre-surgical cognitive fMRI suggests that verbal ...

Linear Systems Analysis of Functional Magnetic Resonance Imaging in Human V1

open access: yesJournal of Neuroscience, 1996
The linear transform model of functional magnetic resonance imaging (fMRI) hypothesizes that fMRI responses are proportional to local average neural activity averaged over a period of time.

Ecological momentary assessment of momentary loneliness, body dissatisfaction, and dysregulated eating in adolescents

open access: yesJCPP Advances, EarlyView.
Abstract Background This objective of this study was to use ecological momentary assessment (EMA) to investigate the relationships of momentary loneliness with body dissatisfaction and dysregulated eating in a diverse sample of adolescents as well as trait peer teasing as a moderator of associations.

Improving Procedure Completion and Engagement of Neurodivergent Patients in Medical Imaging: A Systematic Review

open access: yesJournal of Medical Radiation Sciences, EarlyView.
Neurodivergent patients face barriers in accessing and engaging with medical imaging services. This systematic review aims to identify strategies in the literature to improve imaging procedure completion among neurodivergent patients. ABSTRACT Introduction Neurodivergent conditions such as autism and attention deficit hyperactivity disorder (ADHD) are ...

REST: A Toolkit for Resting-State Functional Magnetic Resonance Imaging Data Processing

open access: yesPLoS ONE, 2011
Resting-state fMRI (RS-fMRI) has been drawing more and more attention in recent years. However, a publicly available, systematically integrated and easy-to-use tool for RS-fMRI data processing is still lacking.

Imaging of epileptic activity using EEG-correlated functional MRI.

open access: yes, 2005
This thesis describes the method of EEG-correlated fMRI and its application to patients with epilepsy. First, an introduction on MRI and functional imaging methods in the field of epilepsy is provided.

Functional Imaging for Identification of Functionally Critical Brain Regions to Spare in Glioma Radiation Therapy Planning: A Systematic Review

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This review highlights the role of functional imaging in sparing cognitive brain regions during glioma radiotherapy. It shows promising dose reduction without compromising target coverage, but evidence remains limited, requiring standardisation and prospective validation.
