Models of Functional Neuroimaging Data [PDF]

Current Medical Imaging Reviews, 2006
Inferences about brain function, using functional neuroimaging data, require models of how the data were caused. A variety of models are used in practice that range from conceptual models of functional anatomy to nonlinear mathematical models of hemodynamic responses (e.g.

Effect of sleep deprivation and NREM sleep stage on physiological brain pulsations

Frontiers in Neuroscience, 2023
IntroductionSleep increases brain fluid transport and the power of pulsations driving the fluids. We investigated how sleep deprivation or electrophysiologically different stages of non-rapid-eye-movement (NREM) sleep affect the human brain pulsations ...

Functional neuroimaging: a physiological perspective [PDF]

Frontiers in Neuroenergetics, 2010
Metabolic physiology and functional neuroimaging have played important and complementary roles over the past two decades. In particular, investigations of the mechanisms underlying functional neuroimaging signals have produced fundamental new insights into hemodynamic and metabolic regulation.

Functional neuroimaging of anxiety: a meta-analysis of emotional processing in PTSD, social anxiety disorder, and specific phobia.

American Journal of Psychiatry, 2007
OBJECTIVE The study of human anxiety disorders has benefited greatly from functional neuroimaging approaches. Individual studies, however, vary greatly in their findings.

Neuroimaging of Brain Networks and Function [PDF]

BioMed Research International, 2015
The human brain consists of multiple interconnected large scale networks. Recent advances in structural and functional neuroimaging techniques have introduced new concepts and approaches to noninvasively assess brain networks, which has attracted enormous research interest.

Cerebrovascular Reactivity Assays Collateral Function in Carotid Stenosis

Frontiers in Physiology, 2020
In patients with carotid artery stenosis (CAS), the risk of stroke, its severity, and response to revascularization are strongly related to the availability of collateral blood flow.

Resting state fast brain dynamics predict interindividual variability in motor performance

Scientific Reports, 2022
Motor learning features rapid enhancement during practice then offline post-practice gains with the reorganization of related brain networks. We hypothesised that fast transient, sub-second variations in magnetoencephalographic (MEG) network activity ...

Assessing inter-individual differences with task-related functional neuroimaging

Nature Human Behaviour, 2019
Explaining and predicting individual behavioural differences induced by clinical and social factors constitutes one of the most promising applications of neuroimaging.

REM-Enriched Naps Are Associated with Memory Consolidation for Sad Stories and Enhance Mood-Related Reactivity

Brain Sciences, 2015
Emerging evidence suggests that emotion and affect modulate the relation between sleep and cognition. In the present study, we investigated the role of rapid-eye movement (REM) sleep in mood regulation and memory consolidation for sad stories.

Optimising a Simple Fully Convolutional Network for Accurate Brain Age Prediction in the PAC 2019 Challenge

Frontiers in Psychiatry, 2021
Brain age prediction from brain MRI scans not only helps improve brain ageing modelling generally, but also provides benchmarks for predictive analysis methods.
