The effect of weightlessness and hypergravity on both hemodynamic and electrophysiological processes in the brain is going to be followed during parabolic flight by EEG and NIRS techniques. A feasibility study of a more complex experiment, which is planned to carry out during medium- and long-term space flight.

Capturing dynamic changes in the protein activation of enucleated red blood cells poses methodological challenges, like the preservation of dynamic changes to acute stimuli for later assessment. The presented protocol describes sample preparation and staining techniques that enable preservation and analysis of relevant protein changes and subsequent detection.
