Cichlid fish larvae were reared from hatching to active free swimming under different gravity conditions: natural environment, increased acceleration in a centrifuge, simulated weightlessness in a clinostat and near weightlessness during space flight. Cytochrome oxidase activity was analyzed semiquantitatively on the ultrastructural level as a marker of(More)
The mitochondrial enzyme, cytochrome oxidase, was localized cytochemically in the nucleus magnocellularis, a primary relay nucleus of vestibular information within the area octavolateralis in the fish brain. Cichlid fish larvae were analyzed after long-term exposure (9 days) to altered gravity situations: increased acceleration in a centrifuge (3 g) and(More)
Electron microscopy of nervous tissue requires on the one hand nanometre resolution for the analysis of fine structures of nerve cell contacts, for instance synaptic vesicles, synaptic membranes and associated organelles. On the other hand, the visualization of the three-dimensional organization of nervous tissue on the level of dendrites and neurites is(More)
The mitochondrial enzyme, cytochrome oxidase, was localized cytochemically in the nucleus magnocellularis, a primary relay nucleus of vestibular information within the area octavolateralis in the fish brain. Larvae of the cichlid fish Oreochromis mossambicus were analyzed at different developmental stages (4, 10, and 35 days post-hatching) and after(More)
