Lay summary
La qualité de sommeil, facteur essentiel au bien-être humain, est mise à mal par le style de vie moderne. Ceci provoque des changements comportementaux, parmi lesquels l'aptitude à prendre des décisions et à évaluer les risques. Ce projet vise a établir des liens entre la qualité de sommeil et les mécanismes cérébraux impliqués dans la prise de décision. Il existe de grande différences individuelles dans la prise de décision. Ce projet a permis pour l'instant: 1) de différentier les individus en fonction de leur propension a prendre des risques et de la cohérence avec laquelle ils prennent des décisions. 2) d'identifier les mécanismes cérébraux qui pourraient expliquer ces différences.

Abstract

A good quality of sleep plays an important role for human well-being. However, modern life- style, in particular the exposure to artificial light and conversely the lack of exposure to natural light (i.e. working without window), jeopardizes human sleep quality and, in turn, might induce large-scale behavioral problems. The most common tool to study sleep is through polysomnography, recording among other things the electrical activity of the brain through electro-encephalography (EEG). The EEG profile during sleep is considered to be highly conservative for an individual, such to be used to differentiate ”good” from ”poor” sleepers. As sleep quality is associated with high-order cognitive processes when awake, individual EEG-traits related to sleep quality might predict individual differences in decision-making. The aim of this thesis is to build a biologically plausible model of (i) the impact of the lighting environment at work on the sleep profile (good and poor sleepers) and (ii) the interaction of the sleep profile with risk and social preferences. Two experiments will be performed. The first characterizes the individual sleep profile of non-pathological good and poor sleepers working either ”with window” or ”without window” and the second tests their risky and prosocial choice behavior in computerized games. In both experiments, brain activity will be recorded using simultaneous coupling of electroencephalography (EEG) and frequency domain functional Near-Infrared Spectroscopy (fNIRS). We will study hospital workers because, on the one hand, their sleep quality is often severely affected by their working situation and, on the other hand, reduced decision quality might have profound consequences for patients.
