eurolab is a Spacelab module mission focusing on the effects of microgravity on the nervous system. The goals of Neurolab are to study basic research questions and to increase the understanding of the mechanisms responsible for neurological and behavioral changes in space. Specifically, experiments will study the adaptation of the vestibular system and space adaptation syndrome, the adaptation of the central nervous system and the pathways which control the ability to sense location in the absence of gravity, and the effect of microgravity on a developing nervou
