Summary
Listening to Eastern Guqin music enhances brain network organization. This study used electroencephalography (EEG) to show music perception optimizes functional brain connectivity and small-world network properties.
Area of Science:
- Neuroscience
- Cognitive Science
- Music Perception
Background:
- Most music perception studies use Western music.
- Eastern music, like Guqin, offers unique insights into auditory processing.
- Understanding music's effect on brain networks is crucial for cognitive neuroscience.
Purpose of the Study:
- To investigate the impact of Guqin music on the large-scale structure of functional brain networks.
- To explore how Eastern music perception influences brain network topology.
- To analyze changes in functional connectivity and network organization during music listening.
Main Methods:
- Electroencephalography (EEG) recorded from non-musician volunteers.
- Phase coherence in the alpha band calculated to create correlation matrices.
- Graph theory applied to analyze network measures (clustering coefficient, characteristic path length).
Main Results:
- Music perception led to higher mean phase coherence.
- Increased clustering coefficient and decreased characteristic path length observed during Guqin music.
- Enhanced small-world network properties and functional connectivity confirmed.
Conclusions:
- Guqin music perception optimizes functional brain network structure.
- Music listening promotes more efficient brain network organization.
- This study highlights the significant impact of Eastern music on neural processing.
