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.
30 maj 2018 · Gravity affects the nervous system of living organisms. This book chapter reviews historical and recent findings on how changes in gravity affect cellular and subcellular parameters of human and animal cells as well as the timing and shaping of complex sensorimotor responses.
8 lis 2021 · Increased mitochondrial respiration and increased glycolysis in human embryonic brain-derived neural stem cells were observed 24 h after exposure to SM.
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.
27 cze 2017 · The previously described effects can be summarized as a gravity-dependent decrease in neuronal conduction velocity (or as an increase in electrical and chemical time constants) under reduced gravity with an increase under hypergravity.
With increased gravity there are initially increased EEG activity in higher frequencies and at around 4 g appears loss of consciousness with accompanying slowing of EEG due to hypoxia. In microgravity, the most prevalent changes in EEG are faster frequencies such as alpha and beta.
10 lut 2024 · Cells perceive changes in the mechanical properties of their environment and alterations in gravity. This perception leads to the elaboration of a biological response which can affect processes at the cell and tissue level.
