title: Effects of +Gz Loads on Structural Organization of Central Autonomic Nuclei.
abstract: Structural alterations in the central autonomic nuclei (dorsal vagal complex and intermediolateral nucleus) of the centrifuged random-bred male rats subjected to +Gz loads were examined. Acute exposure to gravitational loads predominantly produced the reactive changes in these nuclei, while persistently repeated regular loads resulted in cumulation of the destructive alterations. The structural perturbations in the central autonomic nuclei can disturb the autonomic regulation of physiological functions. The character of such disturbances is partially determined by the peculiarities in structural organization of these nuclei.
