What Makes Yawning Contagious? – Neuroscience News
Summary: Yawning is a universal behavior observed in many species, but why do we tend to yawn when someone else does? While the idea that yawning increases brain oxygenation remains…
Neural Circuitry Behind Social Group Preferences Discovered
Summary: Scientists have identified the brain circuitry that drives spiny mice to prefer larger social groups. The study shows that neural signaling from the anterior cingulate cortex (ACC) to the…
Greater Knowledge May Harm Group Welfare
Summary: Increasing knowledge can lead to negative outcomes when individuals use it for self-interest rather than collective good. Researchers argue that enhanced knowledge can reduce cooperation among rational individuals, potentially…
How Music Synchronizes Heart Rates and Collective Emotions
Summary: Listening to music synchronizes heart rates within individuals more reliably than between different people. This synchronization depends on physiological responses rather than mood or music preferences. The findings help…
Shaping Empathy: Adult Brains Can Learn Compassion
