Effect of Acoustic fMRI-Scanner Noise on the Human Resting State [PDF]

, 2022
Our knowledge about the human resting state is predominantly based on either electroencephalographic (EEG) or functional magnetic resonance imaging (fMRI) methods.

Sampling Rate Effects on Resting State fMRI Metrics [PDF]

Frontiers in Neuroscience, 2019
Low image sampling rates used in resting state functional magnetic resonance imaging (rs-fMRI) may cause aliasing of the cardiorespiratory pulsations over the very low frequency (VLF) BOLD signal fluctuations which reflects to functional connectivity (FC). In this study, we examine the effect of sampling rate on currently used rs-fMRI FC metrics. Ultra-

Functional Brain Asymmetry Reveals Heterogeneous Subtypes in Autism Spectrum Disorder

Autism Research, EarlyView.
ABSTRACT Heterogeneity is a critical factor in understanding inter‐individual brain and behavioral variability in autism spectrum disorder (ASD). Since individuals with ASD exhibit atypical communication and social interaction skills closely linked to brain lateralization, this study investigated ASD heterogeneity using an asymmetry index that captures

Correlation between changes in functional connectivity in the dorsal attention network and the after-effects induced by prism adaptation in healthy humans: A dataset of resting-state fMRI and pointing after prism adaptation

Data in Brief, 2019
It has been reported that it is possible to observe transient changes in resting-state functional connectivity (FC) in the attention networks of healthy adults during treatment with prism adaptation. by using functional magnetic resonance imaging (fMRI) (

Evaluation of Statistical Inference on Empirical Resting State fMRI [PDF]

IEEE Transactions on Biomedical Engineering, 2014
Modern statistical inference techniques may be able to improve the sensitivity and specificity of resting state functional magnetic resonance imaging (rs-fMRI) connectivity analysis through more realistic assumptions. In simulation, the advantages of such methods are readily demonstrable.

Occupational Context Moderates the Association Between Agreeableness and Brain Structure

Brain Health, EarlyView.
ABSTRACT Background Previous research on associations between personality traits and brain structure has yielded inconsistent findings, suggesting that such relationships may depend on contextual factors. Methods This study examined whether occupational context moderates the association between agreeableness and gray matter volume (GMV). Structural MRI

Brain Health Deviation Index: A Comprehensive Brain Health Assessment Biomarker for Predicting Cognitive Decline and Polyvascular Stenosis

Brain Health, EarlyView.
ABSTRACT Assessing and quantifying brain health remains a pressing challenge, despite its importance for overall well‐being. Traditional methods that focus on isolated brain measures often fail to capture the multifaceted nature of brain health and may miss early signs of dysfunction.

Continuous EEG source imaging enhances analysis of EEG-fMRI in focal epilepsy

, 2010
Introduction: EEG-correlated fMRI (EEG-fMRI) studies can reveal haemodynamic changes associated with Interictal Epileptic Discharges (IED). Methodological improvements are needed to increase sensitivity and specificity for localising the epileptogenic ...
