Svenja B sends her regards from the European Sleep Research Society’s Sleep Science School “The Functions of Sleep” currently taking place at the beautiful Villa Clythia in Frèjus, France. She just gave a talk about information processing in the transition to sleep and how we can image the locus coeruleus–noradrenergic system in humans. This fantastic retreat features great lectures by Gabrielle Girardeau, Vlad Vyazovskiy, Iben Lundgaard, Monika Schönauer et al.
