Neuromotor changes in postural control following bed rest

The Journal of Physiology, EarlyView.
Abstract figure legend Prolonged bed rest (BR) (both horizontal and head‐down tilt) leads to neuromotor adaptations that impair postural control. Structural and functional changes occur in the brain, including a reduction in grey and white matter volume, alterations in functional connectivity, and shifts in cerebrospinal fluid distribution.

A model for plasma volume changes during short duration spaceflight [PDF]

It is well established that plasma volume decreases during spaceflight and simulated weightlessness (bedrest). The decrement in plasma volume is thought to contribute to the orthostatic intolerance that has been observed in some crew members following ...

Dynamic changes in perivascular space morphology predict signs of spaceflight-associated neuro-ocular syndrome in bed rest

npj Microgravity
During long-duration spaceflight, astronauts experience headward fluid shifts and expansion of the cerebral perivascular spaces (PVS). A major limitation to our understanding of the changes in brain structure and physiology induced by spaceflight stems ...
