Background:
Anatomical studies have indicated that the brain and the heart are connected through multiple pathways. However, the functional interplay between them is unclear, especially for different task states. This study explored the brain-heart interplay under reflexive and voluntary saccade tasks.
Methods:
The Synthetic Data Generation model was used to quantify the interplay between the brain and heart.
Results:
Bidirectional interplay patterns were found between the brain and heart under different frequency bands for the two types of saccade task. There were significant variations in the interplay coupling across saccade tasks, particularly in the prefrontal and parietal lobes. This phenomenon can be explained by the complexity and cognition load among the saccade tasks.
Conclusions:
This study shed light on the dynamic bidirectional interplay mechanisms between the brain and heart, contributing to the understanding of brain-heart interaction.
