Precision Functional Mapping of the Individual Human Brain Near Birth Cortical areas are a fundamental organizational property of the brain, but their development in humans is not well understood. Key unanswered questions include whether cortical areas are fully establi...

Newborn brains already show individual patterns of functional organization. 🧠✨
