[Intermittent exposure to hypergravity of rats deprived of support to the hind limbs. analysis of the somatosensory cortex ultrastructure].
Intermittent hypergravity was evaluated as a method to prevent the unfavorable nervous effects of microgravity. It was shown that intermittent exposure to hypergravity (2 G, 1 h. a day) of rats during 24-d tail-suspension put a barrier to changes in the ultrastructure of the brain somatosensory cortex associated with a reduction in the afferent input to the somatosensory cortex from the hind limbs.
