Oscillations are at the heart of living systems. It is our common interest to investigate the origin and functions of neuronal oscillations during sleep. We prepared our International Scientific Conference on Sleep Spindling and Related Phenomena due to recent advances in this specific field of study as well as the key importance of this neural oscillatory pattern in neurobehavioral functioning. Since sleep spindle oscillations are at the crossroad between slow and fast oscillations during sleep, the conference is open to scientific results about a very broad range of neural and behavioural phenomena. We highly appreciate contributions from prospective keynote speakers, speakers or other participants alike.
