[The cerebrovascular effects of motion sickness].
In rabbits with implanted electrodes, a diminished reactivity of vascular vessels to functional tests of physical and chemical nature was revealed although the level of cerebral blood flow generally increased. This suggests a reduction of compensatory capacity of the brain circulation system which can result in a change of the brain tissue water balance under the effects leading to an alteration of cerebral outflow and sometimes accompanying seasickness. This was corroborated by the evidence on a change in cerebral tissue impedance under the combined effect of antiorthostatism and seasickness, as well as by the evidence on dynamics of cerebral rheogram pulse waves.
