Internal jugular pressure increases during parabolic flight. [PDF]

Physiol Rep, 2016
AbstractOne hypothesized contributor to vision changes experienced by >75% of International Space Station astronauts is elevated intracranial pressure (ICP). While no definitive data yet exist, elevated ICP might be secondary to the microgravity‐induced cephalad fluid shift, resulting in venous congestion (overfilling and distension) and inhibition ...

Human limb position sense measured by repositioning during changes of gravity in parabolic flight [PDF]

Scientific Reports
Our sense of limb position is believed to be signalled by muscle spindles. To confirm this, we previously sought evidence for spindles contributing to each of three different methods of measuring position sense.
