Music interventions and obstructive sleep apnea: a brain connectivity analysis.

Area of Science:

• Neuroscience
• Medical Research

Background:

• Obstructive sleep apnea (OSA) is a serious condition causing breathing difficulties during sleep and increasing risks of heart attack and stroke.
• Brain connectivity analysis is proposed to investigate the impact of OSA under different auditory conditions.

Purpose of the Study:

• To investigate the impact of obstructive sleep apnea (OSA) on brain connectivity patterns.
• To analyze brain connectivity during exposure to specific music types (Neelambari, Kapi) and silence.

Main Methods:

• Electroencephalogram (EEG) recordings were collected from 12 subjects under three conditions: Neelambari music, Kapi music, and no music.
• EEG signals were pre-processed using bandpass and notch filters, and sub-bands (delta, theta, alpha, beta) were extracted using wavelet packet decomposition (WPD).
• Brain connectivity was assessed using Pearson Correlation on WPD detail coefficients and graph theory's node strength metric.

Main Results:

• Listening to Neelambari music (Music 1) significantly increased brain connectivity in the right hemisphere's frontal and temporal regions (F8, FC6, T8).
• High correlation values were observed across all frequency bands (delta, theta, alpha, beta) during Neelambari music exposure, indicating strong neural synchronization.
• Neelambari music demonstrated stronger neural synchronization compared to Kapi music, with consistently higher correlation values.

Conclusions:

• Obstructive sleep apnea (OSA) patients show positive brain connectivity when listening to Neelambari music.
• Neelambari music may positively modulate brain dynamics and neural synchronization in OSA patients.
