Background:

Inter-subject alignment is crucial for enhancing statistical power in functional MRI (fMRI) group analyses.
Current methods primarily rely on anatomical data, potentially limiting the capture of functional variations.

Purpose of the Study:

To develop and validate a novel multi-subject algorithm for aligning fMRI data based on functional connectivity patterns.
To demonstrate the efficacy of this functional alignment approach in improving group-level fMRI analyses.

Main Methods:

A new algorithm was developed to derive functional correspondence by aligning spatial patterns of functional connectivity across multiple subjects.
The method was tested using fMRI data acquired during a movie-viewing experiment.
Cross-validation was performed using a separate movie dataset to assess generalization.

Main Results:

The proposed algorithm successfully aligned functional connectivity patterns across subjects.
The derived functional correspondence demonstrated generalization to an independent dataset.
This suggests improved potential for statistical power in group fMRI studies.

Conclusions:

Functional connectivity-based alignment offers a promising alternative to traditional anatomical methods for fMRI data.
The developed algorithm provides a robust and generalizable approach for inter-subject fMRI analysis.
This method has the potential to enhance the sensitivity and reliability of neuroimaging research findings.
