AbstractLow frequency coherent rsfMRI signals (<0.1Hz) do not match the bandwidth of established neuronal oscillations, highlighting a gap in our knowledge regarding the neuronal basis of rsfMRI underlying long-range brain networks. In this study, optogenetics and rsfMRI were combined to investigate the neuronal basis of rsfMRI connectivity by probing alternations of brain functional connectivity before, during and after low frequency stimulation in dorsal dentate gyrus. Our results demonstrated that low frequency optogenetic stimulation enhanced brain functional connectivity. This indicated that low frequency neuronal oscillations contribute and underlie the synchronized long-range rsfMRI brain functional networks.
