[HTML][HTML] Astrocytic Ca2+ signaling is reduced during sleep and is involved in the regulation of slow wave sleep
Astrocytic Ca 2+ signaling has been intensively studied in health and disease but has not
been quantified during natural sleep. Here, we employ an activity-based algorithm to assess …

Deletion of aquaporin‐4 improves capillary blood flow distribution in brain edema
Brain edema is a feared complication to disorders and insults affecting the brain. It can be
fatal if the increase in intracranial pressure is sufficiently large to cause brain herniation. …
