The circadian system consists of individual cellular clocks. It organizes and synchronizes biochemical and physiological processes in order to optimally adapt an organism to its environment. This requires that the circadian system is responsive to environmental cues, which contain information about geophysical time (e.g., light), and allows an organism to predict daily recurring events....

Sustained anxiety is a key symptom of anxiety disorders and may be associated with neural activation in the right inferior parietal lobe (rIPL), particularly under unpredictable threat. This finding suggests a moderating role of the rIPL in sustained anxiety, which we tested in the current study. We applied cathodal or sham transcranial direct current stimulation (tDCS) to the rIPL as a...

Introduction: Anhedonia, a core symptom of Major Depressive Disorder (MDD), manifests as a lack or loss of motivation as reflected by decreased reward responsiveness, at both behavioral and neural (i.e., striatum) levels. Exposure to stressful life events is another important risk factor for MDD. However, the mechanisms linking reward-deficit and stress to MDD remain poorly understood. Here,...

Le stress et l’épuisement touchent de plus en plus d’étudiants infirmiers. Toutefois, peu d’études ont été réalisées sur le sujet, notamment en Suisse. De plus, les étudiants sont plus vulnérables face aux différents stresseurs et ont peu de connaissances sur les moyens pour y faire face. Les objectifs de ce travail sont d’explorer les facteurs de stress perçus, les stratégies...

Introduction: Reward and stress are important determinants of motivated behaviors. Striatal regions play a crucial role in both motivation and hedonic processes. So far, little is known on how cognitive effort interacts with stress to modulate reward processes. This study examines how cognitive effort (load) interacts with an unpredictable acute stressor (threat-of-shock) to modulate motivational...

Humans have a propensity to pursue rewards and to avoid punishments. The motivation to seek rewards and the ability to experience and to learn from positive consequences are fundamental functions in the reward processing. They promote survival and well-being. However, these functions can be challenged or impaired by stressful events or contexts. To clarify the determinant factors that might...
