The brain at rest or during periods of relative inactivity, complex dynamical patterns of activity spontaneously form over the entire brain. In this study, we plan to clarify the convergence and divergence of spontaneous brain activity across humans and marmosets. We investigated the spontaneous brain dynamics of marmosets, and compared its convergence and divergence with human neuroimaging results. We identified seven representative FC patterns (FC states) in the resting-state activity of marmosets. The most prevalent two FC patterns (VC1 and VC2) corresponds to a state of BOLD coherence of primary visual and auditory processing regions. Our results suggested that the spontaneous activity does reflect the inherent properties of the brain of marmosets.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
