Background:

Brain networks feature central hubs crucial for inter-regional communication.
Analyzing brain activity in specific frequency bands reveals unique network architectures.
Identifying hubs across multiple frequency bands simultaneously remains a challenge.

Purpose of the Study:

To develop a novel method for identifying brain network hubs across different frequency bands.
To leverage multiplex network analysis for a more accurate representation of brain functional networks.
To assess the utility of multiplex hubs in differentiating healthy and schizophrenic populations.

Main Methods:

Representing each frequency band as a layer in a multiplex network.
Applying advanced multiplex network topology analysis.
Comparing hubs identified in the multiplex network with those from conventional methods.

Main Results:

Each frequency band provides distinct topological information essential for accurate brain network modeling.
Multiplex network hubs differ from conventional hub identification methods.
Multiplex network hubs offer a more precise map of functionally important brain regions.

Conclusions:

Multiplex network analysis provides a superior framework for understanding brain functional connectivity across frequencies.
The identified multiplex hubs enhance the ability to distinguish between healthy and schizophrenic individuals.
This approach advances the study of brain networks and their alterations in neurological conditions.
