註釋

Four Navy enlisted men were exposed in a slow rotation room (SRR) by stepwise increases over a period of 16 days to a terminal velocity of 10 rpm. The fact that overt symptoms of motion sickness at 10 rpm were prevented solely by the incremental increases demonstrated that adaptive processes somehow inhibited irradiation of vestibular activity to cell assemblies in areas concerned in the genesis of symptoms. The SRR sickness observed in other subjects suddenly exposed to 10 rpm thus may result from failure of homeostatic processes, permitting such irradiation. The underlying processes therefore are clearly nonhomeostatic in nature and produce a nonhomeostatic state. The findings have practical as well as theoretical implications. (Author).
