A Randomized Global Signal Regression Method for Resting State Functional Connectivity Studies
INTRODUCTION: The presence of negative correlations between the default mode network (DMN) and the dorsal attention network (also known as the task positive network (TPN) [1] has been a subject of recent controversy in the resting-state functional MRI (fMRI) literature. It has been suggested that the negative correlations could be an artifact caused by global signal regression performed during ...
متن کاملTowards a consensus regarding global signal regression for resting state functional connectivity MRI
The number of resting state functional connectivity MRI studies continues to expand at a rapid rate along with the options for data processing. Of the processing options, few have generated as much controversy as global signal regression and the subsequent observation of negative correlations (anti-correlations). This debate has motivated new processing strategies and advancement in the field, ...
متن کاملAssociation between resting-state functional connectivity and empathizing/systemizing
Empathizing is the drive to identify the mental status of other individuals and respond to it with an appropriate emotion; systemizing is the drive to analyze a system. Previously, we have shown that structures associated with the default mode network (DMN) and external attention system (EAS) are associated with empathizing and systemizing, respectively. Here we investigated the association bet...
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...
متن کاملThe association between resting functional connectivity and dispositional optimism
Dispositional optimism is an individual characteristic that plays an important role in human experience. Optimists are people who tend to hold positive expectations for their future. Previous studies have focused on the neural basis of optimism, such as task response neural activity and brain structure volume. However, the functional connectivity between brain regions of the dispositional optim...
