Core Concept: Resting-state connectivity.
In the early days of functional magnetic resonance imaging (fMRI), researchers mostly analyzed how brain areas responded to a stimulus, whether a light, a noise, or some sort of cognitive task. But as a graduate student at the Medical College of Wisconsin in Milwaukee, Bharat Biswal had an unusual request of his fMRI test subjects: climb into the scanner and do, well, nothing. Biswal expected t...
متن کاملResting State Functional Connectivity in Perfusion Imaging: Correlation Maps with BOLD Connectivity and Resting State Perfusion
Functional connectivity is a property of the resting state that may provide biomarkers of brain function and individual differences. Classically, connectivity is estimated as the temporal correlation of spontaneous fluctuations of BOLD signal. We investigated differences in connectivity estimated from the BOLD and CBF signal present in volumes acquired with arterial spin labeling technique in a...
متن کاملResting-state functional connectivity in neuropsychiatric disorders.
PURPOSE OF REVIEW This review considers recent advances in the application of resting-state functional magnetic resonance imaging to the study of neuropsychiatric disorders. RECENT FINDINGS Resting-state functional magnetic resonance imaging is a relatively novel technique that has several potential advantages over task-activation functional magnetic resonance imaging in terms of its clinical...
متن کاملResting-state Functional Connectivity During Controlled Respiratory Cycles Using Functional Magnetic Resonance Imaging
Introduction: This study aimed to assess the effect of controlled mouth breathing during the resting state using functional magnetic resonance imaging (fMRI). Methods: Eleven subjects participated in this experiment in which the controlled “Nose” and “Mouth” breathings of 6 s respiratory cycle were performed with a visual cue at 3T MRI. Voxel-wise seed-to-voxel maps and whole-brain region of i...
