  • Title: [Ultrastructure of the cortex of the cerebellar nodulus in rats after a flight on the biosatellite Kosmos-1514].

    Abstract:
    The ultrastructure of moss fibers and granule cells of the cortex of the cerebellum nodulus of rats flown for 5 days onboard the biosatellite Cosmos-1514 and exposed to 1 g for 6-8 hours upon return to Earth is indicative of an excess excitation of terminals of moss fibers and excitation of granule cells. The excitation of moss fiber terminals reflect the excitatory state of hair cells of the otolith apparatus and neurons of the vestibular ganglion produced by the effect of 1 g after exposure to microgravity. This state can be viewed as evidence of a greater sensitivity of the hair cell of the otolith organ--neuron of the vestibular ganglion system during exposure to microgravity. It is hypothesized that the sensitivity of this system of other mammals may also increase in microgravity.
