Higher spatial resolution and sensitivity in whole brain functional MRI at 7T using 3D EPI accelerated with variable density CAIPI sampling and temporal random walk

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To develop an efficient 3D EPI encoding technique for high spatiotemporal resolution functional MRI. Methods To exploit spatiotemporal fMRI data structure, we introduce a variable density 2D CAIPI sampling in the spatial domain combined with time‐wise extra random encoding in the time domain, thus achieving pseudo‐regular sampling with

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

NeuroImage: 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

Block‐interleaved segmented echo‐planar imaging for improved activity detection in submillimeter high‐resolution functional MRI at 7 T

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Isotropic submillimeter high‐resolution functional MRI (fMRI) facilitates noninvasive investigation of neuronal activities at the mesoscale level, including cortical columns and laminae. However, the task‐evoked functional activity becomes less detectable when using single‐shot echo planar imaging (EPI) with parallel imaging techniques

Comprehensive Review of the Impact of Maternal Stress on Fetal Development

Pediatric Discovery, EarlyView.
ABSTRACT Maternal stress impacts millions of pregnant women across the globe each year and refers to mental or psychological stress that occurs during the prenatal period. Although it remains known that maternal stress can negatively impact maternal health, the downstream effects of stress on fetal and infant development in the long‐term are unclear ...

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

NeuroImage, 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.

Resting-State fMRI

, 2014
Although brain plasticity is greatest in the first few years of life, the brain continues to be shaped by experience throughout adulthood. Advances in fMRI have enabled us to examine the plasticity of large-scale networks using blood oxygen level-dependent (BOLD) correlations measured at rest.

Study on the Vocal Fold Movement Characteristics of Canine Models With Nerve Paralysis Caused by Different Site Injuries

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To explore the specific effects of unilateral injuries to the vagus nerve (VN), recurrent laryngeal nerve (RLN), and superior laryngeal nerve (SLN) on the vocal fold movement characteristics, and investigate the regulation pattern of current intensity on the vocal fold movement after the injuries.
