To investigate the role of slow waves in the generation of CSF pulsations, we analyzed functional MRI data obtained across the full sleep-wake cycle and during a respiratory task during wakefulness. This revealed a novel generating mechanism that relies on the autonomic regulation of cerebral ...
This cycle coincided with(与……一致) the rhythm of the brain's slow waves-an electrical activity that happens when we're in deep sleep. 他们发现,每隔20秒,血液就从大脑中流出,为大量脑脊液进入大脑和“清洁”留出空间.这个周期正好与大脑慢波的节律(当我们进入深度睡眠时发生的一种电活动)相吻合。

Delta brain waves occur during deep “slow-wave” sleep in stages 3 and 4. Delta waves are the slowest the brain produces, between 0.5 and 4 Hz. As mentioned in the previous section, during the earlier stage 2 sleep you’ll find sleep spindles, but you’ll also find k-complexes, which...
Brain activity during sleep is characterized by circuit-specific oscillations, including slow waves, spindles and theta waves, which are nested in thalamocortical or hippocampal networks. A major challenge is to determine the relationships between these oscillatory activities and the identified networks of...
there’s an overnight dialogue between the hippocampus – the brain’s memory hub – and the cerebral cortex, which is associated with higher brain functions like reasoning and planning. This occurs during a phase of deep sleep, when brain waves are especially slow and neurons across brain regi...
Researchers at the University of California, Berkley found that during sleep important brain waves are produced that play key roles in storing memories. Sleep loss can affect memory in seniors Researchers studied the brain waves of a small group of adults as they listened to the recorded sounds ...
5 Characterization of EEGs and ISF waves in hippocampus during natural sleep-wake cycle with chemogenetic inhibition. a, Representative traces of EEG, EMG, and ionic waves in the hippocampus during wake, NREM, and REM with chemogenetic inhibition. Top right scale bar: 200 ms and 200 µV...

is in session, which means everyone needs to be quiet and still. At this point, your sleep is deep enough that you are no longer aware of the world around you. Your brain has told your eyes to stop moving and allows your body temperature to drop. Your brain waves start to slow down...
