Measuring sleep: accuracy, sensitivity, and specificity of wrist actigraphy compared to polysomnography.
TLDR
It is concluded that actigraphy is overall a useful and valid means for estimating total sleep time and wakefulness after sleep onset in field and workplace studies, with some limitations in specificity.
Human relational memory requires time and sleep
TLDR
It is demonstrated that human relational memory develops during offline time delays, and sleep appears to preferentially facilitate this process by enhancing hierarchical memory binding, thereby allowing superior performance for the more distant inferential judgments, a benefit that may operate below the level of conscious awareness.
The Sleeping Brain's Influence on Verbal Memory: Boosting Resistance to Interference
TLDR
By introducing interference after sleep, this study confirms an experimental paradigm that demonstrates the active role of sleep in consolidating memory, and unmasks the large magnitude of that benefit.
Symptoms and suffering at the end of life in children with cancer.
TLDR
Greater attention must be paid to palliative care for children who are dying of cancer, as many have substantial suffering in the last month of life, and attempts to control their symptoms are often unsuccessful.
Memory for Semantically Related and Unrelated Declarative Information: The Benefit of Sleep, the Cost of Wake
TLDR
The results demonstrate that sleep does in fact stabilize declarative memories, diminishing the negative impact of subsequent wakefulness, and sleep is most beneficial to memory 24 hr later if it occurs shortly after learning.
Sleep Neurophysiological Dynamics Through the Lens of Multitaper Spectral Analysis.
TLDR
It is demonstrated how multitaper spectral analysis makes the oscillatory structure of traditional sleep states instantaneously visible, closely paralleling the traditional hypnogram, but with a richness of information that suggests novel insights into the neural mechanisms of sleep, as well as novel clinical and research applications.
The impact of body posture and sleep stages on sleep apnea severity in adults.
TLDR
Supine-Dominance and REM-dominance commonly contribute to AHI underestimation in single-night PSGs, and misclassification of OSA severity can be mitigated in a patient-specific manner by appropriate consideration of these variables.
