Caloric stimulus testing was performed as part of the vestibular research program during the European Spacelab 1 mission in Nov/Dec 1983. Contrary to prediction according to the classical endolymph flow theory originally forwarded by Bárány, caloric nystagmus was elicited in both tested astronauts. The intensity of the response was found comparable to that measured on earth. The theoretical consequences of these findings are discussed and possible mechanisms are considered. The direct volume displacement hypothesis is favoured as the primary effect responsible for the observed vestibulo-ocular nystagmus. Estimated differential pressure conditions resulting in the endolymph canal support this hypothesis and are in agreement with the observed response intensity. It is further speculated that interaction in the central vestibular system between canal and otolith signals be responsible for the well-known body position modulation of the observed nystagmus.
1983年11月/12月欧洲空间实验室1号任务期间，作为前庭研究项目的一部分进行了冷热试验。与最初由巴兰尼提出的经典内淋巴流动理论的预测相反，两名受试宇航员均诱发了冷热性眼震。发现反应强度与在地球上测得的强度相当。讨论了这些发现的理论后果并考虑了可能的机制。直接容积位移假说被认为是导致观察到的前庭眼震的主要效应。导致内淋巴管的估计压差条件支持这一假说，并与观察到的反应强度一致。进一步推测，管和耳石信号在前庭中枢系统中的相互作用是观察到的眼震众所周知的体位调制的原因。
