Story summary
- A study published February 10, 2026, in PLOS Biology reports that synchronizing activity between the frontal and parietal brain regions increases altruistic choices.
- Researchers from East China Normal University and the University of Zurich stimulated frontal and parietal lobes in 44 participants during a Dictator Game.
- The stimulation increased gamma oscillation synchrony and yielded more generous money allocations, even at personal cost, implying altruism may arise from synchronized brain activity.
