Dynamic reconfiguration of cortical functional connectivity across brain states

Abstract: Throughout each day, the brain displays transient changes in state, as evidenced by shifts in behavior and vigilance. While the electrophysiological correlates of brain states have been studied for some time, it remains unclear how large-scale cortico-cortical functional connectivity systematically reconfigures across states. Here, we investigate state-dependent shifts in cortical functional connectivity by recording local field potentials (LFPs) during spontaneous behavioral transitions in the ferret using ch… Show more

“…The dynamics of the system can then be interrogated within this low-dimensional space, offering insights into the mechanisms that underlie the system's function. These approaches have successfully been used in the past to elucidate the functional brain circuitry that underlies the behavioral repertoires of a diverse range of organisms, including the nematode (Caenorhabditis elegans), the fruit fly (Drosophila melanogaster) and the ferret (Mustela putorius furo) [11][12][13][14] .…”

“…In rodents, ECoG approaches have been employed to investigate patterns of synchrony in visual cortex (Toda et al, 2018). We have recently used ECoG implants to investigate phase coupling during spontaneously occurring state changes in the ferret (Stitt et al, 2017).…”

“…For studies chronically implanted animals, ECoG arrays are advantageous because of the long-term stability of the implant and the recorded signals (Rubehn et al, 2009; Bosman et al, 2012; Bastos et al, 2015; Stitt et al, 2017). Thus, they permit repetitive and long-term tracking of brain activity and the investigation of spatiotemporal neural patterns under a broad variety of experimental conditions.…”

“…Complex network dynamics are a topic of substantial interest 108 , particularly in computational and network neuroscience [109][110][111][112] . Network fluctuations co-occur with a variety of fluctuating cognitive processes within and across rs-fMRI sessions 113,114 To understand how basic dynamics between pairs of coupled systems scale up, we simulated networks dynamics on a structural connectome using connectivity data from Cocomac.…”
