Characteristics of ventromedial thalamic neuronal activity during sleep-wake cycle in mice
陆军军医大学学报, 2022 Objective To investigate the characteristics of ventromedial thalamus (VM) neuronal activity during sleep-wake cycles. Methods Both the oscillation state of electrical activity in the parietal cortex and three-dimensional acceleration of the head and ...

Oscillatory EEG activity during REM sleep in elderly people predicts subsequent dream recall after awakenings [PDF]
, 2019 Several findings underlined that the electrophysiological (EEG) background of the last segment of sleep before awakenings may predict the presence/absence of dream recall (DR) in young subjects.

Changes in dentate gyrus neuronal activity during sleep-wake cycle in mice
陆军军医大学学报, 2023 Objective To investigate the difference of dentate gyrus (DG) neuronal activity between wakefulness and sleep state, and the characteristics of DG neuronal activity during hippocampal sharp wave ripple and θ oscillations. Methods Six 3-month-dd male wild-

Dual enhancement mechanisms for overnight motor memory consolidation [PDF]
, 2017 Our brains are constantly processing past events<sup>1</sup>. These offline processes consolidate memories, leading in the case of motor skill memories to an enhancement in performance between training sessions.

The Mysterious Island: Insula and Its Dual Function in Sleep and Wakefulness
Frontiers in Systems Neuroscience, 2021 In the recent sleep studies, it was shown that afferentation of many cortical areas switches during sleep to the interoceptive one. However, it was unclear whether the insular cortex, which is often considered as the main cortical visceral representation,

Dynamic BOLD functional connectivity in humans and its electrophysiological correlates [PDF]
, 2012 Neural oscillations subserve many human perceptual and cognitive operations. Accordingly, brain functional connectivity is not static in time, but fluctuates dynamically following the synchronization and desynchronization of neural populations.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Emerging evidence suggests that low‐frequency neural oscillations are dynamically regulated by consciousness levels, with the recovery of low cortical activity potentially serving as a neurophysiological substrate for conscious emergence. Targeted enhancement of these low‐frequency rhythms in patients with disorders of consciousness

Computational Modeling of Information Propagation during the Sleep–Waking Cycle
Biology, 2021 Non-threatening familiar sounds can go unnoticed during sleep despite the fact that they enter our brain by exciting the auditory nerves. Extracellular cortical recordings in the primary auditory cortex of rodents show that an increase in firing rate in ...

A Role for the Kolliker-Fuse Nucleus in Cholinergic Modulation of Breathing at Night During Wakefulness and NREM Sleep [PDF]
, 2010 For many years, acetylcholine has been known to contribute to the control of breathing and sleep. To probe further the contributions of cholinergic rostral pontine systems in control of breathing, we designed this study to test the hypothesis that ...
