This August, the Green Man Festival was held in the Brecon Beacons, Wales. As always, it was a celebration of music, art, and science. It also featured a contribution from the PhD students of the Centre for Developmental Neurobiology (CDN) at King’s College London (KCL). Since 2018, these students have been bringing the wonders of neuroscience to Green Man festivalgoers, and this year’s participation was bigger and better than ever, hopefully leaving a lasting impact on those who attended.
