Sponsor: University Hospital, Strasbourg, France
Conditions: Sleep Disorders, Neurological Pathologies, Psychiatric Pathologies, Ophthalmological Pathologies
Interventions: Specific light exposures
Countries: France
The light has visual and non-visual effects on organism and can act on the behavior, the mood, the cognition and the sleep. These effects are mediated by "classical" retina photoreceptors which allow vision (rods, cones) but also melanopsin cells. The non-visual effects of light seems to be altered in many neurological, psychiatric or ophtalmological conditions but their exact role in the pathogenesis remains poorly understand. The purpose of the study is to increase our knowledge of the non-visual effects of light and establish new therapeutic applications
