[2 reactions in caloric stimulation of the labyrinth. Is Bárány's theory disproven?]

Caloric nystagmus in weightless condition is completely inverse to Bárány's nystagmus in optimum downward position. Therefore, another stimulation must prevail over the Bárány effect in the optimum up position which is observed only in weightless condition. The intensity of the two reactions is very different.
