Resting state fMRI: A review on methods in resting state connectivity analysis and resting state networks
- Biology, PsychologyThe neuroradiology journal
The concept of resting state functional magnetic resonance imaging is introduced in detail, three most widely used methods for analysis are discussed, and a few of the resting state networks featuring the brain regions, associated cognitive functions and clinical applications are described.
Resting as Knowing: a Lagged Structure Analysis of Resting State fMRI with Application to Mind Wandering During Oral Reading
- Psychology, Biology
A theoretical analysis of how a lagged analysis of resting state dynamics in fMRI could represent persistent representations of knowledge in the neocortex and a novel procedure using both surface based maps and independent component analysis is applied to a small group of 54 adolescents.

Functional Connectivity Mapping in the Animal Model: Principles and Applications of Resting-State fMRI
- BiologyFront. Neurol.
The longer term goal of integrating fMRI connectivity data with structural connectomes obtained with tracing and optical imaging approaches is presented and will allow the interrogation of fMRI data in terms of directional flow of information and may identify the structural underpinnings of observed functional connectivity patterns.
Characterizing resting‐state networks in Parkinson’s disease: A multi‐aspect functional connectivity study
- Psychology, BiologyBrain and behavior
The aim of this study was to identify the differences between individual RSNs and reveal the most important discriminatory characteristic of R SNs between the HCs and PDs.

Contribution of ultra-slow fMRI fluctuations in the 4th ventricle to our understanding of sleep
The results replicate the observation that forth ventricle ultra-slow fluctuations with inflowlike characteristics are present in scans during which subjects did not comply with instructions to keep their eyes open, and report that the temporal evolution of the power spectrum of these ultra- slow FV fluctuations can help reproduce sample-level sleep patterns.
Dynamic Functional Network Connectivity In Schizophrenia With MEG And fMRI, Do Different Time Scales Tell A Different Story?
The results show that fMRI and MEG reveal between-group functional connectivity differences in distinct ways, highlighting the utility of using each of the modalities individually, or potentially a combination of modalities, to better inform the understanding of disorders such as schizophrenia.
Resting-State Seed-Based Analysis: An Alternative to Task-Based Language fMRI and Its Laterality Index
- Biology, PsychologyAmerican Journal of Neuroradiology
FALFF can be used as an alternative to task-based fMRI for assessing language laterality and the efficacy of fALFF for predicting the laterality of task- based fMRI is demonstrated.

Resting-State Functional Connectivity in Rat Brain
The measurement of resting-state functional connectivity on rats at 9.4T using contrast-agent (ferumoxtran-10) based functional signal, with the assumption that the influence of cardiac pulsation through blood is minimal due to very short T2 of venous blood under this condition, is reported.
Frequencies contributing to functional connectivity in the cerebral cortex in "resting-state" data.
- Medicine, BiologyAJNR. American journal of neuroradiology
Functional connectivity in the auditory, visual, and sensorimotor cortices is characterized predominantly by frequencies slower than those in the cardiac and respiratory cycles, which are characterized by a high degree of temporal coherence.
Functional Connectivity in Single and Multislice Echoplanar Imaging Using Resting-State Fluctuations
Correlations to left hemisphere motor cortex, visual cortex, and amygdala are measured in long resting-state scans and these correlations are extended to lower sampling rate multislice echoplanar acquisitions and other right/left hemisphere-symmetric functional cortices.

Functional connectivity in the motor cortex of resting human brain using echo‐planar mri
- Biology, PsychologyMagnetic resonance in medicine
It is concluded that correlation of low frequency fluctuations, which may arise from fluctuations in blood oxygenation or flow, is a manifestation of functional connectivity of the brain.

- Biology, PsychologyProceedings of the National Academy of Sciences
A universal architecture of positive and negative functional connections, as well as consistent loci of inter-individual variability are demonstrated, which demonstrate that independent R-fMRI datasets can be aggregated and shared.
