Abstract
Galactic cosmic radiation, which can harm sensitive neurons and structures, changes in gravitational acceleration that change the terrestrial synergies between perception and action, and a variety of factors (isolation, confinement, a different atmosphere, and mission parameters, including distance from Earth) that can affect cognition and behaviour are just a few of the environmental challenges that space travel presents to the central nervous system. In order to better understand and lessen the effects of these extended exposures, space-faring nations continue to invest heavily in research. Mars travellers will be subjected to these environmental problems for up to three years. The results of more than 50 years of space-related neuroscience studies on people and animals subjected to spaceflight or settings that are similar to spaceflight are reviewed in this article, along with their implications and the future work needed to ensure successful Mars missions. It also discusses basic neurophysiology reactions that are important for understanding and preserving human health and performance on Earth.
