Discover how gravity impacts brain function and cognition in this insightful article from BBC Science Focus Magazine.
Mar 25, 2019 · 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.

So where does my research fit into this? Well, I think that certain parts of the brain end up receiving way too much blood because nitric oxide – an invisible molecule which is usually floating around in the blood stream – builds up in the bloodstream. This makes the arteries supplying the brain with blood relax, so that they open up too much. As a...
By climbing and then dipping through the air, this plane performs up to 30 of these “parabolas” in a single flight to simulate the feeling of weightlessness. They last only 30 seconds and I must admit, it’s very addictive and you really do get a puffy face!

Nov 28, 2019 · To counteract the effect of gravity, humans and tall vertebrates have developed a host of short-term neuronal and long-term humoral adjustments (Fig. 24.1) which correct and maintain a steady mean arterial pressure during change in posture or sudden acceleration. These are largely absent in the gill-breathing aquatic species and mammalian embryos surrounded by the amniotic fluid, where the ...

Dec 1, 2021 · Current evidence indicates that the internal model of gravity effects is qualitative and does not comply with physics exactly. Indeed, as mentioned above, people systematically underestimate the motion duration of constant speed targets descending along the vertical and activate their arm muscles too early to intercept them (McIntyre et al., 2001; Zago et al., 2004).

Mar 1, 2021 · Currently, more is known about the influence of in-flight (Stage 2) stressors and resilience factors on neurophysiology and behavior compared to pre-flight or post-flight effects. Therefore, the in-flight section provides a more comprehensive analysis of spaceflight effects on the human brain and behavior compared to the other two sections.
