Neural Oscillations Underlying the Neural Gating of Respiratory Sensations in Generalized Anxiety Disorder.
Liang et al., Respir Physiol Neurobiol 2024
DOI: 10.1016/j.resp.2024.104215
What’s New: This study explores the neural oscillatory activities associated with altered neural gating of respiratory sensations (NGRS) in individuals with generalized anxiety disorder (GAD), which has not been previously investigated.
Importance: Understanding the neural mechanisms of altered respiratory perception in GAD can contribute to better diagnosis and treatment strategies for the disorder.
Contribution to Literature: The research adds to the existing knowledge by using both time and time-frequency analysis to examine NGRS in GAD, revealing specific alterations in neural oscillations.
Results Summary:
– The GAD group exhibited smaller N1 amplitudes to the first stimulus and altered evoked gamma and beta oscillations (lower gamma, larger beta) compared to healthy controls.
– Both GAD and control groups displayed a neural gating phenomenon, with larger N1, P3, beta power, and theta power responses to the first stimulus than to the second.
– The study identifies N1, gamma, and beta frequency oscillations as potential markers for altered respiratory sensation in GAD, while N1, P3, beta, and theta oscillations may serve as indicators of neural gating of respiratory sensations.
