Stimulation of the vaginal cervix with a plunger from a 1 cc syringe induced tonic immobility (i.e., blocked gross movement including the righting reflex) in response to inversion combined with brief manual restraint, in otherwise insusceptible female rats. In a second experiment, estradiol benzoate administration potentiated this effect somewhat, as measured by the latency to immobilization, although the duration of immobility was not significantly affected. Results are discussed in terms of the possible relationship between tonic immobility and lordosis, the immobile mating posture of the female rat, which is also potentiated by cervical stimulation.
用1毫升注射器的活塞刺激阴道子宫颈，在短暂手动约束并倒置的情况下，能使原本不易产生这种反应的雌性大鼠出现强直性静止（即抑制包括翻正反射在内的所有大幅度动作）。在第二个实验中，通过测量静止潜伏期发现，注射苯甲酸雌二醇会在一定程度上增强这种效果，不过静止持续时间并未受到显著影响。本文将根据强直性静止与脊柱前凸（雌性大鼠静止不动的交配姿势，同样也会因子宫颈刺激而增强）之间可能存在的关系来讨论这些结果。
