The objectives of this scientific expedition are: a/ Evaluation of temporal cognitive perception and collective synchronization in a temporally anomalous universe (underground environment), b/ Influence of group living on the endogenous circadian rhythmicity of the central biological clock and peripheral clocks in a "free-running" situation (absence of light/natural darkness), c/Evaluation of cognitive and physiological performance in response to exposure to an extreme environment in a natural underground cavity (cave) without access to a time indicator for 40 days, d/Correlation of cognitive, behavioral, psychological, social, neurophysiological and physiological parameters, e/ Determination of adaptation or maladaptation criteria (biological, genetic, physiological, neurophysiological, psychological and cognitive) in an isolation environment (underground) f/ Study of the evolution of collective organization, decision making and leadership in an extreme isolation and management situation.
