Examining Insula–Default Mode Network Functional Connectivity and Its Relationship with Heart Rate Variability

M. Nogueira, J. D. S. Magalhães, et al.

Discover how the insula and Default Mode Network (DMN) interact at rest and their links to heart rate variability. In 43 healthy adults, structural and functional MRI plus resting HRV tested whether insula activity/volume and insula–DMN connectivity relate to HRV. Findings show clear insula–DMN connectivity and a positive association between left insula volume and HRV, but no direct link between connectivity and HRV—underscoring the complex brain–autonomic relationship.
