The results published in literature of caloric tests in face-up position are compared to these obtained in face-down position. The rates of convective flow and expansion of the endolymph are evaluated. The theory of Bárány continues to be valid, because the rate of convection is greater than that of expansion. Together with the expansion effect the theory explains caloric nystagmus under terrestrial conditions and under conditions in space, i.e. in the absence of gravitation.
