This paper introduces a framework for geometry-constrained coupling between neural manifolds, showing how inter-manifold interactions reorganize dynamics and produce critical transitions in brain activity.

The paper investigates how heart rate influences large-scale brain network dynamics using EEG, fMRI, and HR data during emotional stimuli, finding both direct and obscured neural-cardiac links.

The paper uses intracranial EEG to show that the temporal pole drives amygdala activity in response to emotional stimuli through theta-alpha oscillations modulating high gamma responses.
