- Adults
- Protocol
- Dyadic inter-brain synchrony neurofeedback over inferior frontal gyrus
- Sessions
- 3 sessions within one week
Key findings
- Inter-brain synchrony increased across sessions only in the real group
- Empathy-for-pain declined in sham but was stable with real feedback
- Lower trait empathy predicted larger synchrony gains
186 participants were paired and given three sessions of real or sham neurofeedback targeting brain synchrony between partners. Synchrony rose only with real feedback, and empathy-for-pain stayed stable with real feedback while declining in the sham group.
