It modulates the vasculature but also influences emotions and personality. In this work, we characterized spatiotemporal properties of brain resting-state networks (RSNs) and studied phase–amplitude associations of the pulse amplitude changes (indexing sympathetic activity) with RSNs. Low frequency (LF, < 0.1 Hz) fluctuations in the pulse amplitude consistently preceded LF fluctuations in the RSNs. LF phase dispersion (PD) (lack of synchrony) between RSNs and pulse correlated with the common variability in the measures of personality and emotions. Sp ... |
