Good sleep - its timing and physiological sleep characteristics

Evaluation of subjective sleep quality in hemodialysis patients and its association with hemodialysis timing

Background and Purpose: Sleep disorders are a common problem in patients undergoing hemodialysis. Poor sleep quality is considered as a potential predictor for mortality and reduced quality of life in these patients. This study aimed to evaluate subjective sleep quality in hemodialysis patients and its association with hemodialysis timing. Methods: This descriptive-correlational study was co...

Human sleep spindle characteristics after sleep deprivation.

OBJECTIVE Sleep spindles (12-15 Hz oscillations) are one of the hallmarks of the electroencephalogram (EEG) during human non-rapid eye movement (non-REM) sleep. The effect of a 40 h sleep deprivation (SD) on spindle characteristics along the antero-posterior axis was investigated. METHODS EEGs during non-REM sleep in healthy young volunteers were analyzed with a new method for instantaneous s...

Physiological markers of local sleep.

Substantial evidence suggests that brain regions that have been disproportionately used during waking will require a greater intensity and/or duration of subsequent sleep. For example, rats use their whiskers in the dark and their eyes during the light, and this is manifested as a greater magnitude of electroencephalogram (EEG) slow-wave activity in the somatosensory and visual cortex during sl...
