Resting-state spontaneous fluctuations in brain activity: a new paradigm for presurgical planning using fMRI.
RATIONALE AND OBJECTIVES Task-evoked functional MRI (fMRI) has been used successfully in the study of brain function and clinically for presurgical localization of eloquent brain regions prior to the performance of brain surgery. This method requires patient cooperation and is not useful in young children or if the patient has cognitive dysfunction or physical impairment. An alternative method ...
متن کاملOrigin of Slow Spontaneous Resting-State Neuronal Fluctuations in Brain Networks
Resting or baseline state low frequency (0.01-0.2 Hz) brain activity has been observed in fMRI, EEG and LFP recordings. These fluctuations were found to be correlated across brain regions, and are thought to reflect neuronal activity fluctuations between functionally connected areas of the brain. However, the origin of these infra-slow fluctuations remains unknown. Here, using a detailed comput...
متن کاملCoupling between spontaneous (resting state) fMRI fluctuations and human oculo-motor activity
The recent discovery of incessant spontaneous fluctuations in human brain activity (also termed resting state fMRI) has been a focus of intense research in brain imaging. The spontaneous BOLD activity shows organized anatomical specialization as well as disruption in a number of brain pathologies. The link between the spontaneous fMRI fluctuations and human behavior is therefore of acute intere...
متن کاملAltered Spontaneous Brain Activity in Type 2 Diabetes: A Resting-State Functional MRI Study Running Title: Resting-State Brain Activity in Type 2 Diabetes
Previous research has shown that type 2 diabetes mellitus (T2DM) is associated with an increased risk of cognitive impairment. Patients with impaired cognition often show decreased spontaneous brain activity on resting-state functional magnetic resonance imaging (rs-fMRI). This study used rs-fMRI to investigate changes in spontaneous brain activity among patients with T2DM and to determine the ...
متن کاملFunctional significance of complex fluctuations in brain activity: from resting state to cognitive neuroscience
Behavioral studies have shown that human cognition is characterized by properties such as temporal scale invariance, heavy-tailed non-Gaussian distributions, and long-range correlations at long time scales, suggesting models of how (non observable) components of cognition interact. On the other hand, results from functional neuroimaging studies show that complex scaling and intermittency may be...
