TL;DR
This study investigates how different auditory stimuli affect the brain's emotion network in healthy people, finding no significant changes in network structure.
Contribution
The study introduces a novel approach combining Bayesian statistics and MEG to explore neural correlates of musical therapy in emotional brain networks.
Findings
Network measures under auditory stimuli were equivalent to resting state in all frequency bands.
Emotion brain network topology remained unchanged after auditory stimuli in healthy subjects.
Changes in emotion network topology may not underlie musical therapy's effects.
Abstract
A large body of research establishes the efficacy of musical intervention in many aspects of physical, cognitive, communication, social, and emotional rehabilitation. However, the underlying neural mechanisms for musical therapy remain elusive. This study aimed to investigate the potential neural correlates of musical therapy, focusing on the changes in the topology of emotion brain network. To this end, a Bayesian statistical approach and a cross-over experimental design were employed together with two resting-state magnetoencephalography (MEG) as controls. MEG recordings of 30 healthy subjects were acquired while listening to five auditory stimuli in random order. Two resting-state MEG recordings of each subject were obtained, one prior to the first stimulus (pre) and one after the final stimulus (post). Time series at the level of brain regions were estimated using depth-weighted…
