Cross-sectional MEG analysis reveals altered connectivity patterns in football players, indicating possible developmental implications.

This research aims to evaluate the impact of repetitive head impacts on neural connectivity in youth football players using magnetoencephalography.
Utilized preseason and postseason resting state MEG data from 72 football players and 17 controls.
Applied standard preprocessing techniques and computed coherence values for brain regions.
Employed network-based statistic toolbox and performed ANCOVAs with multiple comparison corrections.
Identified global hypoconnectivity in the delta frequency band among football players post-season.
Observed hyperconnectivity in the theta and beta frequency bands in specific cortical regions for players.
Found no significant differences between preseason and postseason within groups or between groups at preseason.

Bell et al. (2026) studied this question.
