Dopamine‐Deficiency‐Related Reorganization of the Somatomotor Network in Prodromal and Early Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Introduction Network attack tolerance (NAT) measures the brain's ability to sustain information flow despite the loss of critical brain regions. In Parkinson's disease (PD), NAT has been linked to cognitive and motor function. However, it remains unclear how dopaminergic degeneration shapes NAT, and whether it relates to motor symptom ...

Cerebral Autoregulation Evidenced by Synchronized Low Frequency Oscillations in Blood Pressure and Resting-State fMRI

Frontiers in Neuroscience, 2019
Resting-state functional magnetic resonance imaging (rs-fMRI) is a widely used technique for mapping the brain’s functional architecture, so delineating the main sources of variance comprising the signal is crucial.

Reference‐Superimposed Reconstruction (RS‐Recon) for Arterial Spin Labeling

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Conventional arterial spin labeling (ASL) reconstruction suffers from sign‐flipping errors and/or noise bias under strong background suppression (BS), limiting SNR optimization. We propose reference‐superimposed reconstruction (RS‐recon) to enable ideal BS and robust signal recovery.

Calibration‐Free Estimation of Cerebrovascular Reactivity From Resting‐State BOLD fMRI Using Reconstructed Respiratory Fluctuations

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Cerebrovascular reactivity (CVR) provides an important index of vascular health and is conventionally quantified using a hypercapnic gas or breath‐hold challenge in conjunction with blood‐oxygen‐level‐dependent functional magnetic resonance imaging (BOLD‐fMRI).

Cross-species striatal hubs: Linking anatomy to resting-state connectivity

NeuroImage
Corticostriatal connections are essential for motivation, cognition, and behavioral flexibility. There is broad interest in using resting-state functional magnetic resonance imaging (rs-fMRI) to link circuit dysfunction in these connections with ...

Prenatal opioid exposure, and health, social and educational outcomes for school‐aged children: A systematic review

Addiction, EarlyView.
Abstract Background and aims Recent decades have seen a rise in the number of pregnancies exposed to opioids. Whilst evidence of the impact of such exposure on pregnancy and infant outcomes is fairly robust, the impact of prenatal opioid exposure (POE) on longer‐term outcomes for children and young people remains unclear.

RS-FetMRI: a MATLAB-SPM Based Tool for Pre-processing Fetal Resting-State fMRI Data

, 2022
Resting-state functional magnetic resonance imaging (rs-fMRI) most recently has proved to open a measureless window on functional neurodevelopment in utero.
