The adult female rats hoard large quantities of food during proestrus and continue hoarding if ovariectomised at proestrus (Group I). The hoarding score is lowest in diestrus and continue to remain low if ovariectomised during this phase (Group II). The scores in Group I and Group II are reversed in intracerebral administration of Progesterone and Estradiol Benzoate respectively into preoptic areas. The significance of the response is discussed on the basis of built-in feedback mechanism for hoarding cyclicity.
成年雌性大鼠在发情前期会囤积大量食物，若在发情前期进行卵巢切除，它们会继续囤积（第一组）。在动情后期囤积分数最低，若在此阶段进行卵巢切除，分数会持续保持较低水平（第二组）。分别向视前区脑内注射孕酮和苯甲酸雌二醇后，第一组和第二组的分数会发生逆转。基于囤积周期性的内在反馈机制，对这种反应的意义进行了讨论。
