Inter-brain synchrony (or neural synchrony) is the phenomenon where the brain activity of two or more people becomes correlated during social interaction. Their neural rhythms — EEG, HRV — begin to align.
Key Properties
- •Coherence — brain rhythms operate in phase
- •HRV synchronization — heart rate variability aligns between partners
- •Alpha-rhythm coherence — relaxed, attentive states synchronize
- •Bidirectional — both participants influence and are influenced
In ONDA Life
Part 11 lists "Inter-brain Synchrony" as a target: "the brain rhythms of partners begin to operate in a coherent mode." Biological markers include "synchronization of Heart Rate Variability (HRV) between partners and Alpha-rhythm brain coherence." This is co-resonance at the physiological level.
Scientific Basis
Built on: Polyvagal Theory (Porges); Psychoneuroimmunology (Ader & Cohen); neuroplasticity research.
