WebAug 7, 2024 · A variant of the technique called Resting State fMRI (rs-fMRI) has been widely used to examine brain networks while subjects are at rest (Fox and Greicius, 2010; van den Heuvel and Hulshoff Pol, 2010). Graph theory is one of the more novel methods being used for the network-level analysis of the brain. As a novel, non-invasive way to measure spontaneous neural activity in the human brain, resting-state functional magnetic resonance imaging … See more Spontaneous neural activity can be recorded by multiple imaging techniques, such as EEG, MEG, and R-fMRI, each with different … See more Through the combination of R-fMRI and graph theory-based network analysis techniques, intrinsic functional networks of the human brain … See more In this review, we summarized the recent advances in the application of modern graph theory-based network analysis techniques to study the intrinsic or spontaneous human brain functional networks derived … See more c. co2 hydrolysis https://mooserivercandlecompany.com
