Transient gray matter decline during antarctic isolation: Roles of sleep, exercise, and cognition

Abstract Astronauts face significant stress in space, and understanding its neurobiological basis is key to assessing risk and resilience. Analogue environments, like the Antarctic Concordia Station, replicate isolated, confined, and extreme (ICE) conditions. This study assessed brain structure chan...
