Research on the neural basis of consciousness has largely focused either on where and when neural activity represents conscious contents, or on the interactions through which distributed neural populations become integrated. We argue that these approaches can be connected by analysing information relations among neural representations. A perceptual content can be synergistic when it is carried...
Functional connectivity (FC) metrics describe brain inter-regional interactions and may complement information provided by common power-based analyses. Here, we investigated whether the FC-metrics weighted Phase Lag Index (wPLI) and weighted Symbolic Mutual Information (wSMI) may unveil functional differences across four stages of vigilance-wakefulness (W), NREM-N2, NREM-N3, and REM sleep-with...
