In May this year, Stockholm hosted a Keystone Symposium on Adult Neurogenesis, attracting scientists from around the world despite the lack of customary snow. The symposium offered an extraordinary program, covering diverse topics that ranged from the neural stem cell lineage and regulation of neurogenesis to functional aspects of neurogenesis in homeostasis and disease, and even computational modeling. This Meeting Review describes some of the exciting presentations and emerging themes from the symposium, which reveal how much this young field has matured.
