P 161 Coupling of brain arousal and autonomic regulation in the transition from wakefulness to sleep onset during an auditory oddball task in the resting state

Simultaneous downregulation of the autonomic and central nervous system activity enables the gradual physiological state change from wakefulness to sleep onset. Dysregulation of central or autonomic arousal has been found in neurological (Silvani et al., 2016) and psychiatric disorders (Hegerl and Hensch, 2014; Hegerl et al., 2012; Schulz et al., 2016; Schwabedal et al., 2016), often associated with dysregulated sleep-wake patterns.
