Altered spontaneous brain activity in chronic smokers revealed by fractional ramplitude of low-frequency fluctuation analysis: a preliminary study

open access: yesScientific Reports, 2017
Although a substantial body of previous functional magnetic resonance imaging (fMRI) studies have revealed different brain responses to external stimuli in chronic cigarette smokers compared with nonsmokers, only a few studies assessed brain spontaneous ...

Cerebellar imaging for neuroscience at 9.4 T

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose This study explored the possibility of visualizing cerebellar structure and function in vivo with a 9.4 T protocol suitable for neuroscientific experiments. Methods Six healthy individuals were scanned with a 9.4 T acquisition protocol including functional runs using BOLD‐weighted 3D EPI at 0.8 and 0.0 mm isotropic resolution, and a 0 ...

A study of neural activity and functional connectivity within the olfactory brain network in Parkinson's disease

open access: yesNeuroImage: Clinical, 2019
Olfactory dysfunction is an early manifestation of Parkinson's disease (PD). The present study aimed to illustrate potential differences between PD patients and healthy controls in terms of neural activity and functional connectivity within the olfactory

Simultaneous zero echo time fMRI of rat brain and spinal cord

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose Functional assessments of the central nervous system (CNS) are essential for many areas of research. fMRI typically targets either the brain or the spinal cord, but usually not both, because of the obstacles associated with simultaneous image acquisitions from distant fields of view (FOVs) with conventional MRI.

Resting state functional connectivity in the default mode network and aerobic exercise in young adults [PDF]

open access: yes, 2017
Around the world Alzheimer’s Disease (AD) is on the rise. Previous studies have shown the default mode network (DMN) sees changes with AD progression as the disease erodes away cortical areas.

Assessing Executive Function in Pediatric Sleep‐Disordered Breathing Using Functional Neuroimaging

open access: yesOtolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Sleep‐disordered breathing (SDB) affects 10% of children and is associated with poor academic performance related to inattention and executive dysfunction. Yet, the underlying neural mechanisms remain poorly understood, especially in elementary school‐aged children who cannot sit still for functional magnetic resonance imaging.

Stationary EEG pattern relates to large-scale resting state networks – An EEG-fMRI study connecting brain networks across time-scales

open access: yesNeuroImage, 2022
Relating brain dynamics acting on time scales that differ by at least an order of magnitude is a fundamental issue in brain research. The same is true for the observation of stable dynamical structures in otherwise highly non-stationary signals.
