Electrical activity in the oviduct wall of the laying hen was studied. The frequency of spike discharges increased in the magnum and isthmus when the egg approached close to the recording sites. The frequency of discharge remained high in the magnum until the egg had passed, but it decreased in the isthmus during the stay of the egg. In the uterus, a relatively high activity was found immediately after oviposition and this was followed by low activity for about 5 h. Electrical activity began to increase again and reached maximum 1-2 h after the egg entered the uterus. The direction of propagation of electrical activity in the magnum was determined by using two electrodes and was towards the ovary or towards the uterus for periods of several minutes.
对产蛋母鸡输卵管壁的电活动进行了研究。当卵子靠近记录部位时，输卵管膨大部和峡部的尖峰放电频率增加。在卵子通过之前，膨大部的放电频率一直保持较高水平，但在卵子停留期间，峡部的放电频率会降低。在子宫中，产卵后立即发现相对较高的活动，随后约5小时活动较低。卵子进入子宫1 - 2小时后，电活动再次开始增加并达到最大值。通过使用两个电极确定了输卵管膨大部电活动的传播方向，在几分钟的时间内，电活动朝着卵巢或朝着子宫方向传播。
