Finite Element Analysis of Upper Airway in Ansa Cervicalis Stimulation for Obstructive Sleep Apnea

The Laryngoscope, EarlyView.
We developed a subject‐specific FE model to investigate how ACS stabilizes the upper airway in OSA. Simulations demonstrate that caudal traction applied through the hyolaryngeal complex produces coordinated multilevel airway stabilization, with pronounced effects at the retropalatal and retro‐epiglottic regions under physiologic loading.

Attention‐Deficit/Hyperactivity Disorder Through a Circadian Lens: When the Brain's Clock Disrupts Attention Regulation

Medicine Bulletin, EarlyView.
ABSTRACT Attention‐deficit/hyperactivity disorder (ADHD) is increasingly linked to disturbances in circadian regulation, yet this temporal dimension remains insufficiently integrated into research and clinical practice. This perspective synthesises current evidence on circadian misalignment in ADHD, reframing commonly reported sleep disturbances and ...

Neural complexity and the spectral slope characterise auditory processing in wakefulness and sleep.

Auditory processing and the complexity of neural activity can both indicate residual consciousness levels and differentiate states of arousal. However, how measures of neural signal complexity manifest in neural activity following environmental ...

Sleep Assessment in Patients with Inner Ear Functional Disorders: A Prospective Cohort Study Investigating Sleep Quality Through Polygraphy Recordings

Audiology Research
Background/Objectives: The vestibulo-respiratory reflex regulates the tension of the respiratory muscles, which prevents apneas and awakenings during sleep. This study aimed to determine whether functional deficits in the inner ear disturb sleep quality.

The Hidden Burden of Hemifacial Spasm: A Systematic Review of Non‐Motor Symptoms

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Hemifacial spasm (HFS) is a chronic neurological disorder characterized by involuntary contractions of facial muscles. Traditionally regarded as a motor condition, HFS encompasses a spectrum of non‐motor symptoms that are often overlooked but significantly affect patients’ quality of life.

Influence of Extended Wakefulness on Automatic and Nonautomatic Processing

, 1994
We investigated the influence of extended wakefulness on automatic and nonautomatic processes in memory and visual search tasks. Subjects were trained in consistently mapped and variably mapped versions of each task, attaining automatic performance in ...

Hypnagogia: The nature and function of the hypnagogic state

, 1983
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.An analysis of the hypnagogic state (hypnagogia) leads to the conclusion that, far from being a simple phase of sleep, this state or process is a central ...
