“Glymphatic” Neurodegeneration: Is Sleep the Missing Key?

Clinical and Translational Neuroscience
Robust evidence suggests that the glymphatic system plays a key role in preserving brain health. Indeed, its activity in maintaining homeostasis by clearing neurotoxic proteins such as beta-amyloid from the human brain is essential.

The Sleep Opportunity, Need and Ability (SONA) Theory

Journal of Sleep Research, EarlyView.
ABSTRACT ‘How much sleep does one need?’ is a critical question that has been difficult to answer. The long history of sleep research has culminated in population‐derived normative values of 7 to 9 h of sleep per night to avoid dysfunction. Such a wide range is sufficiently large that one cannot know what is required for any given individual.

The glymphatic system for neurosurgeons: a scoping review

Neurosurgical Review
Abstract The discovery of the glymphatic system has revolutionized our understanding of cerebrospinal fluid (CSF) circulation and interstitial waste clearance in the brain. This scoping review aims to synthesize the current literature on the glymphatic system’s role in neurosurgical conditions and its potential as a therapeutic target.

Cerebral and Peripheral Hemodynamics Across Wakefulness and NREM Sleep

Journal of Sleep Research, EarlyView.
ABSTRACT Wake/sleep‐related changes in cerebral hemodynamic oscillations are well established, but similar changes in peripheral hemodynamics remain largely understudied. Moreover, how the relationship between cerebral and peripheral hemodynamics varies across sleep–wake states is not well understood, despite evidence that these oscillations in the low‐

Confined spaces in space: Cerebral implications of chronic elevations of inspired carbon dioxide and implications for long‐duration space travel

Experimental Physiology, EarlyView.
Abstract Cerebrovascular regulation is critically dependent upon the arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_{\mathrm{2}}}}}$), owing to its effect on cerebral blood flow, tissue PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_{\mathrm{2}}}}}$, tissue proton concentration, cerebral metabolism and cognitive and neuronal ...
