DOI: 10.1016/j.bbr.2021.113380
Abstract: Previous studies have shown that the synchronization of electroencephalogram (EEG) signals is found during propofol-induced general anesthesia, which is similar to that of slow-wave sleep (SWS). However, a complete understanding is lacking in terms of… read more here.

Ongoing neural oscillations predict the post-stimulus outcome of closed loop auditory stimulation during slow-wave sleep

DOI: 10.1016/j.neuroimage.2022.119055
Abstract: Large slow oscillations (SO, 0.5-2Hz) characterise slow-wave sleep and are crucial to memory consolidation and other physiological functions. Manipulating slow oscillations may enhance sleep and memory, as well as benefitting the immune system. Closed-loop auditory… read more here.

Activity-Dependent Downscaling of Subthreshold Synaptic Inputs during Slow-Wave-Sleep-like Activity In Vivo

DOI: 10.1016/j.neuron.2018.01.047
Abstract: Summary Activity-dependent synaptic plasticity is critical for cortical circuit refinement. The synaptic homeostasis hypothesis suggests that synaptic connections are strengthened during wake and downscaled during sleep; however, it is not obvious how the same plasticity… read more here.

DOI: 10.1016/j.neuropharm.2018.10.022
Abstract: &NA; Insomnia is one of the most common sleep problems with an estimated prevalence of 10%–15% in the general population. Although adenosine A2A receptor (A2AR) agonists strongly induce sleep, their cardiovascular effects preclude their use… read more here.

DOI: 10.1016/j.nlm.2017.07.001
Abstract: Memory reactivation during slow-wave sleep (SWS) influences the consolidation of recently acquired knowledge. This reactivation occurs spontaneously during sleep but can also be triggered by presenting learning-related cues, a technique known as targeted memory reactivation… read more here.

DOI: 10.1016/j.sleep.2018.04.012
Abstract: OBJECTIVES Levels of steroid hormones such as androgens and cortisol exhibit circadian variation, and their fluctuations are related to the sleep-wake cycle. Currently, the functional role of different stages of sleep in steroid hormone secretion… read more here.

Slow-wave sleep is controlled by a subset of nucleus accumbens core neurons in mice

DOI: 10.1038/s41467-017-00781-4
Abstract: Sleep control is ascribed to a two-process model, a widely accepted concept that posits homoeostatic drive and a circadian process as the major sleep-regulating factors. Cognitive and emotional factors also influence sleep–wake behaviour; however, the… read more here.

DOI: 10.1038/s41467-020-17062-2
Abstract: Astrocytic Ca2+ signaling has been intensively studied in health and disease but has not been quantified during natural sleep. Here, we employ an activity-based algorithm to assess astrocytic Ca2+ signals in the neocortex of awake… read more here.

DOI: 10.1038/s41598-017-04522-x
Abstract: Recent research has found that the human sleep cycle is characterised by changes in spatiotemporal patterns of brain activity. Yet, we are still missing a mechanistic explanation of the local neuronal dynamics underlying these changes.… read more here.
