Slow Wave Activity During Nocturnal Sleep in Hypersomnolence Disorder

Journal of Sleep Research, EarlyView.
ABSTRACT Slow waves during non‐rapid eye movement (NREM) sleep are associated with the restorative aspects of sleep. Previous research has suggested reduced normalized slow wave activity (SWA), particularly in the first cycle of NREM sleep, as a feature of hypersomnolence disorder (HD); however, the scarcity of existing research highlights the need for

Cardiovascular Responses to Natural and Auditory Evoked Slow Waves Predict Post‐Sleep Cardiac Function

Journal of Sleep Research, EarlyView.
ABSTRACT The importance of sleep as a key component of cardiovascular health has been increasingly recognized. Our previous research demonstrated that auditory‐enhanced slow waves increase cardiac function, but the underlying mechanisms behind these beneficial effects remain uncertain. In this study, we examined the influence of two types of slow waves

Strong and Weak Episodic Memories Are Shaped by Multiple Cycles of NREM Spindles and REM Alpha Bursts

Journal of Sleep Research, EarlyView.
ABSTRACT Prior research has built up the notion that non‐rapid eye movement sleep (NREM) and rapid eye movement sleep (REM) are separately important for specific types of memory. However, growing evidence suggests that these sleep stages work in conjunction to jointly shape memory.

Are Age‐Related Differences in Sleep Associated With the Different Trajectories of Fluid and Crystallized Intelligence Across the Lifespan?

Journal of Sleep Research, EarlyView.
ABSTRACT A common misconception is that, with age, cognition deteriorates across all domains. Instead, certain aspects are negatively impacted, while others are relatively spared, or, continue to improve. Specifically, fluid intelligence (i.e., problem‐solving skills) peaks in early adulthood and declines, whereas crystallized intelligence (i.e ...

Sodium Oxybate Alters Sleep Architecture and Reduces Emotional Selectivity in Memory‐Related Responses

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep supports memory consolidation. Non‐rapid eye movement (NREM) and rapid eye movement (REM) sleep have been proposed to support, respectively, declarative memory consolidation and the integration of the memory affective dimension. Here, we used sodium oxybate (SXB) to modify the NREM/REM proportion during one sleep night and assessed ...

Whole‐Night Gentle Rocking Improves Sleep in Poor Sleepers With Insomnia Complaints

Journal of Sleep Research, EarlyView.
ABSTRACT Specific brain oscillations can be manipulated during sleep to improve sleep quality and memory performance. We previously demonstrated that continuous rocking stimulation (0.25 Hz, lateral movement) applied to good sleepers during sleep enhanced stable deep sleep, boosted NREM oscillations (spindles and slow waves) and memory consolidation ...

Sound‐offset encoding is related to speech‐in‐noise perception at sentence level in older adults

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic summary of the study investigating sound‐onset and offset sensitivity in the brain of older adults. EEG responses to white‐noise bursts were recorded to examine neural encoding of sound onset and offset during passive listening and active task conditions.

Distinctive neurophysiological correlates of sound onset and offset perception in humans

The Journal of Physiology, EarlyView.
Abstract figure legend Electroencephalography (EEG) recordings were obtained from participants listening to successive pairs of 1‐2 s noises in a silent background (Study 1) or successive pairs 1‐2 s silent gaps in a noise background (Study 2). Participants heard the same stimuli in the context of either a duration discrimination task (identifying ...

Mastoid Osteoma

Bengal Journal of Otolaryngology and Head Neck Surgery, 2019
Introduction Osteoma of the mastoid region is an uncommon benign tumor of bone. Osteomas may occur in the external auditory canals but are reported to be very rare in the mastoid region, with about 150 cases reported in literature.

Optokinetic stimulation modulates vestibular contribution to postural control

The Journal of Physiology, EarlyView.
Abstract figure legend Healthy young adults completed repeated standing balance trials while receiving stochastic vestibular stimulation (SVS) with or without optokinetic visual motion. Vestibular contributions to postural control were quantified from the frequency‐domain coupling between SVS and mediolateral ground reaction forces using coherence and ...
