Phase-locking of resting-state brain networks with the gastric basal electrical rhythm
Description: A network of myenteric interstitial cells of Cajal in the corpus of the stomach serves as its “pacemaker”, continuously generating a ca. 0.05 Hz electrical slow wave, which is transmitted to the brain chiefly by vagal afferents. In our recent study, we combined resting-state functional MRI (rsfMRI) with concurrent surface electrogastrography (EGG) to investigate whether fluctuations in brain resting state networks (RSNs), estimated using a spatial independent component analysis (ICA) approach, might be synchronized with the stomach. Here we share our RSN maps associated with the study. (Please see the NITRC resource page of the study [https://www.nitrc.org/projects/cerb_2020/] for detailed information regarding the data acquisition parameters and the associated data sets.)
