Rest–Activity Disturbances Correlate with Core Features in Dementia with Lewy Bodies

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Sleep–wake disturbances are a clinically important and poorly studied feature of dementia with Lewy bodies (DLB) due to the challenges of in‐laboratory polysomnography in this population. Objectives To compare rest–activity rhythms in DLB, Parkinson's disease (PD), and age‐matched controls using home‐based wrist actigraphy and ...

Neuronal avalanches differ from wakefulness to deep sleep - evidence from intracranial depth recordings in humans [PDF]

, 2013
Neuronal activity differs between wakefulness and sleep states. In contrast, an attractor state, called self-organized critical (SOC), was proposed to govern brain dynamics because it allows for optimal information coding.

Two types of REM sleep: The atonic and brain REM sleep [PDF]

Sleep and Hypnosis - International Journal, 2016
With preliminary classification, there are five behavioral functions for rapid eye movement(REM) sleep after puberty, which are memory retention, drive dissipation, muscular efficiency, heat control and adaptive immobility. For these diversities, it is newly suggested in this mini-review to categorize the REM sleep into two types respectively as atonic

The Impact of Deep Brain Stimulation of the Subthalamic Nucleus on Sleep–Wake Function and Circadian Rhythms in Patients with Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is a well‐established therapy in advanced Parkinson's disease (PD) improving motor and non‐motor signs including sleep. The mechanisms of sleep improvement are insufficiently understood.
