On testing the peripheral vestibular apparatus of astronauts with healthy labyrinths, nystagmus was observed when flushing the ears with hot or cold water even in the absence of gravitation. In the opinion of some scientists, this seems to refute Bárány's theory. They attempt to explain nystagmus as a result of compression. The hypothesis of Bárány, basing on terrestrial conditions, explains the peripheral impulse as the result of a convective flow caused by heating or cooling within the horizontal semicircular canal. However, if gravitation is absent any such circulation is excluded, because buoyancy is impossible without gravitation. The article shows, on the one hand, that the compression hypothesis cannot be correct, where as on the other Bárány's theory needs completion. For, in addition to the convective flow, the expansion of the endolymph resulting from heat must be considered. This effect occurs even in the absence of gravitation.
在对具有健康内耳的宇航员的外周前庭器官进行测试时，即使在没有重力的情况下，用热水或冷水冲洗耳朵时也会观察到眼球震颤。一些科学家认为，这似乎反驳了巴兰尼的理论。他们试图将眼球震颤解释为压迫的结果。巴兰尼的假说基于地球条件，将外周冲动解释为水平半规管内热或冷引起的对流的结果。然而，如果没有重力，任何这样的循环都被排除，因为没有重力就不可能有浮力。一方面，文章表明压迫假说不可能正确，而另一方面，巴兰尼的理论需要完善。因为，除了对流之外，还必须考虑热引起的内淋巴膨胀。即使在没有重力的情况下，这种效应也会发生。
