We are pleased to announce the 3^RD Sleep Science Winter School for March 1-4, 2020 and to continue the long-standing tradition of this scientific meeting in the stunning Bernese Alps. Our preliminary inspiring program includes two topical keynote lectures given by international experts in the field on microbiota and sleep and the brain mechanisms of awareness and consciousness. Seven scientific sessions provide newest insight into the key topics of the Bern Network of Epilepsy, Sleep and Consciousness (BENESCO). Starting with a session on infraslow oscillations, we continue with the topic of the interrelation of pain and sleep and then deepen the topic of sleep breathing disorders, one of the most common sleep disorders and known for its harmful effects on the cardio-cerebrovascular system. On Tuesday, we start with a session on metabolismand sleep. Thereafter the Interfaculty Research Cooperation “Decoding Sleep” (http://www.sleep. unibe.ch/) organizes a scientific session covering their key research topics. We then round up this Winter School with a session on self-consciousness highlighted from a neuropsychological perspective and last but not least a session on epilepsy looking at the temporal dynamics of seizures from a patient’s chronotype to a single neuron. We also introduce new program elements with two teaching courses for young scientists, a data blitz session and a BENESCO Session where scientists are given a platform to present and discuss their newest research findings. We hope you join us for the upcoming Sleep Science Winter School, On behalf of the BENESCO, the European Sleep Foundation and the organizing committee.
