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.
Local cortical sleep features arise subcortically due to heterogeneous burst discharge in neurons of a sleep rhythm pacemaker previously thought to act uniformly.
A neural circuit that can selectively induce sleep-like patterns in small regions of the brain demonstrates how sleep and arousal states may be controlled in local brain regions.
Different rhythms uniquely contribute to task-related processing in the hippocampus, and changes in the rhythmic profile of the hippocampus reflect dynamic coordination of its cell activity.
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.
