This study, conducted by French Army, evaluates the impact of a five-day sea survival simulation on human adaptive capacities by measuring physiological, sensory, psychological and cognitive parameters using MindPulse. Twenty-one participants were monitored before, during, and after the experiment. The results show cognitive deterioration, mood disturbances, sleep disorders, and sensory hypervigilance. Physiologically, the autonomic nervous system was affected. Even after recovery, some participants continued to show signs of deterioration, raising concerns for future space missions.

This study, conducted by the French military, examines the effects of transcutaneous vagus nerve stimulation (taVNS) on mental and physical health, as well as cognitive performance, using the MindPulse. The results indicate that repeated taVNS administration improves heart rate variability, cognitive performance, and sleep efficiency. However, an increased perception of stress may be associated with the repetition of sessions. These findings suggest that taVNS could be a promising intervention for extreme environments, but further research is needed to confirm these results. The MindPulse here allows for the detection of subtle variations in executive and attentional performance.
