Heart-brain coupling¶

Type: Entity
Confidence: ★★★☆☆ Promising

Evidence Graph¶

Summary¶

Heart rate variability synchronizes with brain waves through vagal mechanisms. Cardiac sympathovagal activity initiates brain responses. High-frequency HRV couples with delta, theta, alpha, beta, gamma bands. RSA quantifies vagal activity.
