Locally recorded calcium events related to slow wave activity show a global cortical fMRI BOLD correlate, establishing a direct relation between a basic neurophysiological signal and the macroscopic perspective of pre-clinical fMRI.
Cortical astrocytes play key roles in NREM sleep by regulating sleep depth and duration through separate GPCR pathways, and differentially control neuronal slow-wave activity in local and remote cortical circuits.
Distinct brain states govern resting state functional architecture revealed by neurophysiologically defined simultaneous optic-fiber-based calcium recordings and task-free functional magnetic resonance imaging (fMRI) in rats.
Retinal waves are correlated with calcium transients in Müller cells, demonstrating that spontaneous activity encompasses both neuronal and glial networks during a crucial period of retinal development.
Sub-second pontine waves functionally interact with hippocampal population activity in a state-dependent manner across sleep states, while brainstem ensemble dynamics exhibit slow, long-lasting state-predictive activity.
