Structural network heterogeneities and network dynamics: a possible dynamical mechanism for hippocampal memory reactivation

, 2006
The hippocampus has the capacity for reactivating recently acquired memories [1-3] and it is hypothesized that one of the functions of sleep reactivation is the facilitation of consolidation of novel memory traces [4-11].

Differential diagnoses of nocturnal fear and movement paroxysm: a case report [PDF]

, 2018
Recurrent nocturnal behavioural and movement paroxysms are a diagnostic challenge for the clinical pediatrician. We report on an adolescent girl who presents recurrent stereotypical nightmare-like episodes occurring during non-REM sleep stages 1-2 (N1 ...

Short Meditation Trainings Enhance Non-REM Sleep Low-Frequency Oscillations

PLOS ONE, 2016
We have recently shown higher parietal-occipital EEG gamma activity during sleep in long-term meditators compared to meditation-naive individuals. This gamma increase was specific for NREM sleep, was present throughout the entire night and correlated with meditation expertise, thus suggesting underlying long-lasting neuroplastic changes induced through

Comparison of positional and rapid eye movement-dependent sleep apnea syndromes

Annals of Thoracic Medicine, 2018
AIM: We aimed to compare the clinical, epidemiological, and polysomnographic features of rapid eye movement (REM)-dependent obstructive sleep apnea syndrome (OSAS) and positional OSAS which are two separate clinical entities.

Sleep-like slow oscillations improve visual classification through synaptic homeostasis and memory association in a thalamo-cortical model

, 2019
The occurrence of sleep passed through the evolutionary sieve and is widespread in animal species. Sleep is known to be beneficial to cognitive and mnemonic tasks, while chronic sleep deprivation is detrimental.

Cerebral correlates of delta waves during non-REM sleep revisited

NeuroImage, 2005
We aimed at characterizing the neural correlates of delta activity during Non Rapid Eye Movement (NREM) sleep in non-sleep-deprived normal young adults, based on the statistical analysis of a positron emission tomography (PET) sleep data set. One hundred fifteen PET scans were obtained using H(2)(15)O under continuous polygraphic monitoring during ...

Behavioural and Neurophysiologic Features of State Dissociation: A Brief Review of the Literature and Three Descriptive Case Studies

Behavioural Neurology, 2010
Wakefulness, rapid eye movement (REM) and non-REM sleep are not always mutually exclusive conditions, as commonly assumed. In some cases, the declaration of any state may be incomplete and states can fluctuate rapidly, resulting in peculiar behavioural ...
