Researchers will compare cognitive performance during normobaric hypoxia exposure to cognitive performance during normoxia (control situation).\n\nParticipants will:\n\n* Session S0. Perform a battery of neuropsychological tests and questionnaires). EEG will be recorded during tests. A cheek swab will be performed.\n* Sessions S1 and S2. Perform several cognitive tasks while exposed to hypoxia and to normoxia (2 different sessions, randomized order) in a normobaric chamber. These are standardized cognitive tests administered on a computer and cognitive tests embedded in a flight simulator scenario. Various questionnaires will be performed on a regular basis. Several physiological measurements will be performed continuously: EEG, ECG, SpO2 and breathing rate. Blood pressure will be measured at the beginning and at the end of hypoxia\u002Fnormoxia exposure. A blood sample will also be performed. At last, participants will inhale air or oxygen through a mask while making a cognitive task in the chamber.",[115,116,117,118,119,120,121,122,123],"Hypoxia","Hypoxia Brain","Hypoxia Altitude Simulation Test","Hypoxia in Healthy Individuals","Hypoxia, Altitude","Hypoxia, Brain","Altitude","Altitude Hypoxia","Normobaric Hypoxia",[125,126,127],"prospective memory","working memory","flight simulator","NOT_YET_RECRUITING","2026-05-09",{"date":131,"type":132},"2026-05-13","ACTUAL",{"date":134,"type":109},"2026-05-06",{"date":136,"type":109},"2026-12-31",{"name":5,"class":6},1]
