Query: Small variation in dynamic functional connectivity in cerebellar
  networks   Brain networks can be defined and explored through their connectivity. Here,
we analyzed the relationship between structural connectivity (SC) across 2,514
regions that cover the entire brain and brainstem, and their dynamic functional
connectivity (DFC). To do so, we focused on a combination of two metrics: the
first assesses the degree of SC-DFC similarity and the second is the intrinsic
variability of the DFC networks over time. Overall, we found that cerebellar
networks have a smaller DFC variability than other networks in the brain.
Moreover, the internal structure of the cerebellum could be clearly divided in
two distinct posterior and anterior parts, the latter also connected to the
brainstem. The mechanism to maintain small variability of the DFC in the
posterior part of the cerebellum is consistent with another of our findings,
namely, that this structure exhibits the highest SC-DFC similarity relative to
the other networks studied. By contrast, the anterior part of the cerebellum
also exhibits small DFC variability but it has the lowest SC-DFC similarity,
suggesting a different mechanism is at play. Because this structure connects to
the brainstem, which regulates sleep cycles, cardiac and respiratory
functioning, we suggest that such critical functionality drives the low
variability in the DFC. Overall, the low variability detected in DFC expands
our current knowledge of cerebellar networks, which are extremely rich and
complex, participating in a wide range of cognitive functions, from movement
control and coordination to executive function or emotional regulation.
Moreover, the association between such low variability and structure suggests
that differentiated computational principles can be applied in the cerebellum
as opposed to other structures, such as the cerebral cortex.
