Histochemical investigations on the influence of long-term altered gravity on the CNS of developing cichlid fish: results from the 2nd German Spacelab Mission D-2.

Abstract

The effect of long-term (10 days) altered gravitational conditions upon succinate dehydrogenase (SDH) reactivity in total brains as well as in individual brain nuclei of developing cichlid fish larvae had been investigated by means of semiquantitative histochemical methods (densitometric grey value analysis). Increasing accelerations from near weightlessness (spaceflight) via 1g controls to 3g hyper gravity (centrifuge) resulted in slightly increasing "all over the brain" (total brain) SDH reactivity. When focusing on distinct neuronal integration centers within the same brains in order to find the anatomical substratum of the gross histochemical data, significant effects of altered gravity only within vestibulum related brain parts were obtained.
