Prolonged microgravity exposure during long-duration spaceflight (LDSF) produces unusual
physiologic and pathologic neuro-ophthalmic findings in astronauts. These microgravity …

Spaceflight and its associated stressors, such as microgravity, radiation exposure,
confinement, circadian derailment and disruptive workloads represent an unprecedented …

Background There is limited information regarding the effects of spaceflight on the
anatomical configuration of the brain and on cerebrospinal fluid (CSF) spaces. Methods We …

Astronauts who undergo prolonged periods of spaceflight may develop a unique
constellation of neuro-ocular findings termed Spaceflight Associated Neuro-Ocular …

New Findings What is the central question of this study? Recently, an internal jugular
venous thrombus was identified during spaceflight: does microgravity induce venous and/or …

Background Sedentary behaviour might be a potential risk factor for cognitive decline.
However, the short-term effects of sedentary behaviour on (cerebro) vascular and cognitive …

Although human adaptation to spaceflight has been studied for decades, little is known
about its long-term effects on brain and behavior. The present study investigated …

It is well known that exposure to microgravity in astronauts leads to a plethora physiological
responses such as headward fluid shift, body unloading, and cardiovascular deconditioning …

This review focuses on the effects of different body positions on intracranial fluid dynamics,
including cerebral arterial and venous flow, cerebrospinal fluid (CSF) hydrodynamics, and …

The microgravity ocular syndrome (MOS) results in significant structural and functional
ophthalmic changes during 6-mo spaceflight missions consistent with an increase in …
