Bayesian semiparametric multi-state models [PDF]
, 2008 Multi-state models provide a unified framework for the description of the evolution of discrete phenomena in continuous time. One particular example is Markov processes which can be characterised by a set of time-constant transition intensities between ...

A Hypothalamic Switch for REM and Non-REM Sleep [PDF]
Neuron, 2018 Rapid eye movement (REM) and non-REM (NREM) sleep are controlled by specific neuronal circuits. Here we show that galanin-expressing GABAergic neurons in the dorsomedial hypothalamus (DMH) comprise separate subpopulations with opposing effects on REM versus NREM sleep.

Antidepressant suppression of REM and spindle sleep impairs hippocampus-dependent learning and memory but fosters striatal-dependent strategies [PDF]
, 2011 REM sleep enhances hippocampus-dependent associative memory but has little impact on striatal-dependent procedural learning. Antidepressant medications like desipramine (DMI) inhibit rapid-eye-movement (REM) sleep but it is little understood how ...

The Memory Function of Noradrenergic Activity in Non-REM Sleep [PDF]
Journal of Cognitive Neuroscience, 2011 AbstractThere is a long-standing assumption that low noradrenergic activity during sleep reflects mainly the low arousal during this brain state. Nevertheless, recent research has demonstrated that the locus coeruleus, which is the main source of cortical noradrenaline, displays discrete periods of intense firing during non-REM sleep, without any signs

Brain Age from the Electroencephalogram of Sleep [PDF]
, 2018 The human electroencephalogram (EEG) of sleep undergoes profound changes with age. These changes can be conceptualized as "brain age", which can be compared to an age norm to reflect the deviation from normal aging process.

Sleep Dysfunction in Fibromyalgia and Therapeutic Approach Options [PDF]
, 2020 Fibromyalgia, characterised by persistent pain, sleep disturbance, fatigue and cognitive dysfunction, is a central sensitivity syndrome that also involves abnormality in peripheral generators and in the hypothalamic pituitary adrenal axis.

A probabilistic model for the ultradian timing of REM sleep in mice.
PLoS Computational Biology, 2021 A salient feature of mammalian sleep is the alternation between rapid eye movement (REM) and non-REM (NREM) sleep. However, how these two sleep stages influence each other and thereby regulate the timing of REM sleep episodes is still largely unresolved.
