When presented with an auditory sequence, the brain acts as a predictive-coding device that extracts regularities in the transition probabilities between sounds and detects unexpected deviations from these regularities. Does such prediction require conscious vigilance, or does it continue to unfold automatically in the sleeping brain? The mismatch(More)
BACKGROUND It is well recognized that sleep is severely disturbed in patients in intensive care units (ICU) and that this can compromise their rehabilitation potential. However, it is still difficult to objectively assess sleep quantity and quality and the determinants of sleep disturbance remain unclear. The aim of this study was therefore to evaluate(More)
With globalization and widespread technological advances, new international issues have emerged that hold critical importance for transnational economic integration, state sovereignty, and the future of global governance. These issues notably affect the power, authority, sovereignty, and legitimacy of states as defined in the Westphalian system. Overall,(More)
BACKGROUND In epidemiological surveys, cognitive decline has been found to be associated with both short and long sleep duration. OBJECTIVE Our goal was to objectively determine how total sleep time (TST) at night was associated or not with apathy or severity scores in patients with Alzheimer 's disease (AD). METHODS During an observational first step(More)

During visual perception, automatic bottom-up and controlled top-down processes occur simultaneously and interact in a complex way, making them difficult to isolate and characterize. In rare neurological conditions, such a dissociation can be achieved more easily. In the present work, we studied a patient (AC) with a posterior lesion of the corpus callosum(More)
