About this Research Topic
In this Research Topic, we aim to provide a summary of current thoughts regarding the following origins of the rs-fMRI signal:
● Neuroelectric: based on electrophysiological measurements
● Neurometabolic: based on measurement of glucose/oxygen metabolism as well as of metabolites
● Neurovascular: based on the vascular nature of the fMRI signal
● Artifactual: signal contributions from putative noise sources
This Research Topic initiative welcomes contributions addressing any of these attributes of the rs-fMRI signal. We welcome original research papers, reviews and commentaries, including but not limited to research based on MRI, MRS, PET, EEG, MEG, ECoG and optical-imaging methods. It is our hope that this series of publications will clarify current debates regarding the interpretation of the rs-fMRI signal and help identify future research questions that help to realize the full potential of rs-fMRI as a powerful brain-mapping approach.
