Intermittent and continuous electrical stimulation of the nipples elicited milk-ejection responses in the lactating rat. The responses occurred intermittently, with similar amplitudes and periodicity as those seen in suckled rats. The responses were always associated with synchronization of the electroencephalogram (EEG), but some rats with synchronized EEG activity did not milk eject during stimulation. Since continuous stimulation also resulted in intermittent milk ejection it seems unlikely that the periodicity of the reflex in suckled rats depends upon changes in the intensity of sensory stimulation. The techniques of nipple stimulation may be a useful method with which to study neural pathways and other phenomena such as gating involved in oxytocin release and milk ejection. The success of the technique depends on a variety of factors such as parameters of the stimulation and state of anaesthesia.
对哺乳期大鼠的乳头进行间歇性和持续性电刺激可引发排乳反应。这些反应呈间歇性发生，其幅度和周期性与哺乳大鼠所见相似。这些反应总是与脑电图（EEG）的同步化相关，但有些脑电图活动同步化的大鼠在刺激过程中并未排乳。由于持续刺激也会导致间歇性排乳，因此哺乳大鼠反射的周期性似乎不太可能取决于感觉刺激强度的变化。乳头刺激技术可能是一种有用的方法，可用于研究神经通路以及其他现象，如催产素释放和排乳过程中涉及的门控现象。该技术的成功取决于多种因素，如刺激参数和麻醉状态。
