Oxygen dependency of cognition: Neural mechanisms of reversible cognitive changes in Tibetan highlanders during altitudinal migration

Key Points

• Cognitive changes occur in Tibetan highlanders due to variations in oxygen levels, suggesting an adaptive neural mechanism.
• Research shows that decreased oxygen on lower altitudes can temporarily impair cognitive function, impacting altitude adaptation.
• Observational analysis reveals that neural mechanisms adapt alongside oxygen changes during altitudinal migration.
• Findings may enable better understanding of cognitive flexibility among populations in hypoxic environments.
