   Mar 1, 2021 · The framework encompasses changes in brain function as well as several measures of brain structure including gray and white matter changes, and intracranial fluid shifts. Critically, the inclusion of behavioral measures aids in the interpretation of whether brain functional or structural changes are adaptive or dysfunctional.

   While cautious interpretation is appropriate given the small sample size and number of comparisons, these findings suggest that brain structural changes are associated with changes in cognitive and motor test scores and with the development of spaceflight-associated neuro-optic syndrome.

   Jun 27, 2024 · Microgravity results in headward fluid shifts, ventricular expansion, an upward shift of the brain within the skull, and remodelling of grey and white matter. The fluid changes are correlated with changes to perivascular space and spaceflight associated neuro-ocular syndrome.

   How does gravity affect the cardiovascular system?

   • Gravity is a relentless fact of life on Earth. With each change in posture, the vector of all hydrostatic pressure gradients is altered, and regional pressures affected. Due to the elongated shape of the human body, our cardiovascular system is particularly sensitive and when upright gravity reduces cardiac output by remarkable 2 L/min.

   Does microgravity affect the brain?

   • While negative behavioral changes have been the focus of much research, microgravity exposure also induces adaptive brain processing of visual, vestibular, and proprioceptive information ( Paloski et al., 1992, 1994; Reschke et al., 1998 ).

   How does gravitational stress affect blood pressure?

   • In response to the gravitational stress, an intricate system of baroreceptors and compensating blood pressure reflexes have evolved. The most important baroreceptors are located just below the brain and thus at an advantageous position to monitor and safeguard blood pressure and flow to the brain.

   How will space travel affect the brain?

   • That is, even MRI measures collected within several hours of return will likely reflect readaptation to Earth’s gravitational environment, which could complicate interpretations of both functional and structural brain metrics. It is worth noting that, as space tourism becomes more prevalent, the profile of space travelers will change.

   Does gravity affect CSF homeostasis?

   • Our findings support the need for advanced neuroimaging protocols and long-term follow-up imaging of the astronaut population. Most important, understanding the influences of gravity on CSF homeostasis and brain health may provide insights into abnormalities of CSF homeostasis such as idiopathic normal pressure hydrocephalus.
