1 mar 2021 · Research over the past decade has demonstrated two co-occurring patterns of spaceflight effects on the brain and behavior: dysfunction and adaptive plasticity. Evidence indicates the spaceflight environment induces adverse effects on the brain, including intracranial fluid shifts, gray matter changes, and white matter declines.
Gravity also affects the flow of blood through the brain; at accelerations beyond 5g, this begins to affect the brain’s electrical activity, producing patterns that resemble epileptic seizures.
19 maj 2022 · Utilizing spaceflight and its ground-based analog, the authors show how the Earth’s gravity sustains the human brain’s orientation-dependent sensitivity to biological motion signals based...
5 lut 2020 · The effects of microgravity conditions on neurovestibular, cardiovascular, musculoskeletal, bone metabolic, and hemato-immunological systems are described.
2 cze 2019 · 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.
15 cze 2017 · Gravity and the Human Body. Our bodies function necessarily under the presence of gravity; how blood pumps, a sense of balance and bone growth are all due to life in a world where gravity is an inescapable reality.
1 mar 2021 · Based on the evidence available to date, we propose that spaceflight effects on the brain represent both adaptations as well as impairments. The altered sensory inputs of microgravity provide a unique environment for inducing adaptive plasticity in the central nervous system.
