Cellular changes in the nervous system when exposed to gravitational variation.

This review discusses the past and recent findings on how changes in gravity affect cellular and subcellular parameters of the human nervous system and the implementation of cell and tissue models of nervous tissue on space biology. In order to prepare for long duration space exploration, a focus on space life sciences research is critical. Such research not only improves our knowledge of the basic biological processes but also elucidates the mechanisms and treatment of various earthly medical conditions. However, the study of living organisms in space poses many challenges that may be negligible or nonexistent in ground-based research. In recent years, with an increase in the number of spaceflights, extended periods of stay of astronauts on the International Space station and the imminent possibility of future long term deep space exploration missions, there is a great deal of attention focused on the effects induced by altered gravitation on the human body, and in particular, on bone, skeletal muscle, immunity and brain function. The aim of this review is to collate, encapsulate and examine the effects of altered gravity on neuronal cell structure and function that have been established from data obtained during experiments performed in real microgravity and simulated microgravity like conditions.
