Objectives of the subject, its place in the medical curriculum: Aim of the course: providing up-to-date, scientifically grounded knowledge on the physiological, behavioural, psychological and clinical aspects of sleep-waking states and related chronobiological phenomena. Multidisciplinarity, integrative approaches and the emphasis of rhythmic processes are the defining features of the course. Theoretical lectures are always completed with clinical corners, exemplifying the biomedical relevance of the mechanisms and processes detailed in the presentation. In turn, clinical topics are accompanied by sections termed theoretical relevance, unravelling the modelling consequences of the respective disorders. |
