Sawtooth waves during REM sleep after administration of haloperidol combined with total sleep deprivation in healthy young subjects [PDF]
, 2002 We sought to examine the possible participation of dopaminergic receptors in the phasic events that occur during rapid eye movement (REM) sleep, known as sawtooth waves (STW).

Regional Delta Waves In Human Rapid Eye Movement Sleep
Journal of Neuroscience, 2019 Although the EEG slow wave of sleep is typically considered to be a hallmark of nonrapid eye movement (NREM) sleep, recent work in mice has shown that slow waves can also occur in REM sleep. Here, we investigated the presence and cortical distribution of

Acta paediatrica, 2020 Understanding the links between sleep and brain development is important, as rapid eye movement (REM) sleep and non‐REM (NREM) sleep seem to contribute to different aspects of brain maturation.

Scientific Reports, 2017 For generations, the evaluation of speech abnormalities in neurodegenerative disorders such as Parkinson’s disease (PD) has been limited to perceptual tests or user-controlled laboratory analysis based upon rather small samples of human vocalizations ...

Non-rapid eye movement sleep with low muscle tone as a marker of rapid eye movement sleep regulation
BMC Neuroscience, 2006 Background It was recently reported that epochs of non-REM sleep (NREMS) with low muscle tone represent a partial correlate of REM sleep (REMS). To further investigate this phenomenon, episodes of restricted night-time sleep (23:00 – 03.00h) and ...

Perspectives on the rapid eye movement sleep switch in rapid eye movement sleep behavior disorder [PDF]
Sleep Medicine, 2013 Rapid eye movement (REM) sleep in mammals is associated with wakelike cortical and hippocampal activation and concurrent postural muscle atonia. Research during the past 5 decades has revealed the details of the neural circuitry regulating REM sleep and muscle atonia during this state.

Differential Effects of Psychological and Physical Stress on the Sleep Pattern in Rats [PDF]
, 2007 In the present study, we investigated the acute effects of 2 different kinds of stress, namely physical stress (foot shock) and psychological stress (non-foot shock) induced by the communication box method, on the sleep patterns of rats.

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.

IEEE Access, 2019 To overcome the disadvantage of clinical manual sleep staging, a convenient, economical, and efficient multi-class automatic sleep staging method is proposed based on long short-term memory network (LSTM) using single-lead electrocardiogram signals. From
