Deep residual networks for automatic sleep stage classification of raw polysomnographic waveforms [PDF]
, 2018 We have developed an automatic sleep stage classification algorithm based on deep residual neural networks and raw polysomnogram signals. Briefly, the raw data is passed through 50 convolutional layers before subsequent classification into one of five ...

Characteristic Effects of Anti-dementia Drugs on Rat Sleep Patterns
Journal of Pharmacological Sciences, 2009 The present study was undertaken to clarify the effects of anti-dementia drugs on sleep pattern in rats. Electrodes were chronically implanted into the frontal cortex and the dorsal neck muscle of rats for the electroencephalogram (EEG) and ...

Automated scoring of pre-REM sleep in mice with deep learning
Scientific Reports, 2021 Reliable automation of the labor-intensive manual task of scoring animal sleep can facilitate the analysis of long-term sleep studies. In recent years, deep-learning-based systems, which learn optimal features from the data, increased scoring accuracies ...

An Asymmetrical Hypothesis for the NREM-REM Sleep Alternation—What Is the NREM-REM Cycle?
Frontiers in Neuroscience, 2021 Since the discovery of rapid eye movement (REM) sleep (Aserinsky and Kleitman, 1953), sleep has been described as a succession of cycles of non-REM (NREM) and REM sleep episodes.

Effects of valerian extract on the sleep-wake cycle in sleep-disturbed rats. [PDF]
, 2005 The present study was performed to investigate the effects of valerian extract on the sleep-wake cycle using sleep-disturbed model rats. A significant shortening in sleep latency was observed with valerian extract at doses of 1000 and 3000 mg/kg.

Complex Propagation Patterns Characterize Human Cortical Activity during Slow-Wave Sleep [PDF]
, 2011 Cortical electrical activity during nonrapid eye movement (non-REM) sleep is dominated by slow-wave activity (SWA). At larger spatial scales (similar to 2-30 cm), investigated by scalp EEG recordings, SWA has been shown to propagate globally over wide ...

The Deep Sleep Optimizer: A Human-Based Metaheuristic Approach
IEEE Access, 2023 Owing to the no free lunch theorem, no single optimisation algorithm can solve all optimisation problems accurately, so new optimisation techniques are required. In this paper, a novel metaheuristic called the deep sleep optimiser (DSO) is proposed.

Essential thalamic contribution to slow waves of natural sleep [PDF]
, 2013 Slow waves represent one of the prominent EEG signatures of non-rapid eye movement (non-REM) sleep and are thought to play an important role in the cellular and network plasticity that occurs during this behavioral state.

Role of corticosterone on sleep homeostasis induced by REM sleep deprivation in rats. [PDF]
PLoS ONE, 2013 Sleep is regulated by humoral and homeostatic processes. If on one hand chronic elevation of stress hormones impair sleep, on the other hand, rapid eye movement (REM) sleep deprivation induces elevation of glucocorticoids and time of REM sleep during the
