Coupled electrophysiological, hemodynamic, and cerebrospinal fluid oscillations in human sleep
Sleep is essential for both cognition and maintenance of healthy brain function. Slow waves
in neural activity contribute to memory consolidation, whereas cerebrospinal fluid (CSF) …

Human REM sleep recalibrates neural activity in support of memory formation
The proposed mechanisms of sleep-dependent memory consolidation involve the overnight
regulation of neural activity at both synaptic and whole-network levels. Now, there is a lack …

Homer1a drives homeostatic scaling-down of excitatory synapses during sleep
Sleep is an essential process that supports learning and memory by acting on synapses
through poorly understood molecular mechanisms. Using biochemistry, proteomics, and …

Microglia regulate sleep through calcium-dependent modulation of norepinephrine transmission
Sleep interacts reciprocally with immune system activity, but its specific relationship with
microglia—the resident immune cells in the brain—remains poorly understood. Here, we …
