It is possible that one of the essential functions of sleep is to take out the garbage, as it were, erasing and “forgetting” information built up throughout the day that would clutter the synaptic network that defines us. It may also be that this cleanup function of sleep is a general principle of neuroscience, applicable to every creature with a nervous system. # {#article-title-106}

Research on sleep spindles and their correlates has progressed steadily over the last decade. The subject has evolved from a simple topic of investigation to an emerging research field, as indicated this year by the first international conference on sleep spindles in Budapest, Hungary, as well as the launching of a scientific journal (i.e., Sleep Spindles and Cortical Up States: A Multidisciplinary Journal) on this topic. This increasing interest has been fueled by reports of associations of sleep spindle characteristics with diseases such as schizophrenia (Ferrarelli et al., 2007, 2010; Manoach et al.), Parkinson’s disease (Christensen et al.), REM sleep behavior disorder (Christensen et al., 2014; O’Reilly et al., 2015), Alzheimer’s disease (Montplaisir et al., 1995; Rauchs et al., 2008), autism (Limoges et al., 2005), and mental retardation (Shibagaki et al., 1982), with recovery processes following brain stroke (Gottselig et al., 2002), with cognitive faculties such as memory consolidation and intelligence (Fogel and Smith, 2011), and with sleep preservation (Landis et al., 2004; Dang-Vu et al., 2010; Schabus et al., 2012). Nonetheless, many methodological difficulties have been encountered in reliably detecting sleep spindles. Hence, this research topic was launched as a forum for proposing better practices in the study of sleep spindles and to provide new insights on spindle correlates. Authors were invited particularly to propose open-access resources that could help promote improved methods and support standardization in the field.

CONTRIBUTIONS

A total of 17 papers were accepted for publication on the research topic, with 10 being focussed particularly on methodological issues such as spindle detection and the remaining seven providing new insights on sleep spindle correlates.

Cell adhesion molecules and sleep, Neuroscience Research

pdf: ocallaghan-et-al-2016-review

Cell adhesion molecules (CAMs) play essential roles in the central nervous system, where some families are involved in synaptic development and function. These synaptic adhesion molecules (SAMs) areinvolved in the regulation of synaptic plasticity, and the formation of neuronal networks. Recent findingsfrom studies examining the consequences of sleep loss suggest that these molecules are candidates to actin sleep regulation. This review highlights the experimental data that lead to the identification of SAMsas potential sleep regulators, and discusses results supporting that specific SAMs are involved in differ-ent aspects of sleep regulation. Further, some potential mechanisms by which SAMs may act to regulatesleep are outlined, and the proposition that these molecules may serve as molecular machinery in thetwo sleep regulatory processes, the circadian and homeostatic components, is presented. Together, thedata argue that SAMs regulate the neuronal plasticity that underlies sleep and wakefulness.

Sleep loss and structural plasticity, Current Opinion in Neurobiology

pdf: areal-et-al-2017

Wakefulness and sleep are dynamic states during which brain
functioning is modified and shaped. Sleep loss is detrimental to
many brain functions and results in structural changes localized
at synapses in the nervous system. In this review, we present
and discuss some of the latest observations of structural
changes following sleep loss in some vertebrates and insects.
We also emphasize that these changes are region-specific and
cell type-specific and that, most importantly, these structural
modifications have functional roles in sleep regulation and brain
functions. Selected mechanisms driving structural
modifications occurring with sleep loss are also discussed.
Overall, recent research highlights that extending wakefulness
impacts synapse number and shape, which in turn regulate
sleep need and sleep-dependent learning/memory.
