Intergenerational Brain Synchrony During Collaborative Drawing
ETH Zurich researchers examined how brain activity synchronises between younger and older adults during joint drawing over six weeks. They found that while same-age pairs showed increasing synchrony, cross-generational pairs experienced a decline, suggesting that mutual prediction rather than shared cognition drives synchrony. The study also identified stable two-brain states and highlighted differences in internal brain synchronisation between participants.

The use of portable wearable brain sensors and longitudinal neural data analysis exemplifies technologies that can be leveraged by Swiss AI research to advance neuroimaging, brain‑computer interfaces, and social cognition modeling.
