Sleep neuroimaging: Review and future directions

open access: yesJournal of Sleep Research, EarlyView.
Summary Sleep research has evolved considerably since the first sleep electroencephalography recordings in the 1930s and the discovery of well‐distinguishable sleep stages in the 1950s. While electrophysiological recordings have been used to describe the sleeping brain in much detail, since the 1990s neuroimaging techniques have been applied to uncover

MRI‐based surrogates of brain clearance in narcolepsy type 1

open access: yesJournal of Sleep Research, EarlyView.
Summary Brain clearance involves the drainage of waste molecules from the brain, a process that is suggested to be amplified during sleep. Recently proposed MRI‐based methods attempt to approximate human brain clearance with surrogate measures. The current study aimed to explore whether two brain clearance surrogates are altered in narcolepsy.

Cerebral and Peripheral Hemodynamics Across Wakefulness and NREM Sleep

open access: yesJournal 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‐
