Andersen P.，H.布鲁兰B。R.卡达通过隔刺激激活海马CA 1区。
用诱发电位方法证实了家兔在氯醛糖麻醉下隔-海马投射的存在。它的起源是大细胞内侧隔核。这些离隔纤维可能通过单突触途径激活CAI神经元的顶树突和/或索马的基部。反复刺激和士的宁可使CAI神经元的去极化面积增加，缺氧可使其减少。因此，根据兴奋性水平，更小或更大部分的顶端树突可以启动尖峰的全或无字符。
Andersen P., H. Bruland B. R. Kaada. Activation of the field CA1 of the hippocampus by septal stimulation.
In rabbits under urethane-chloralose anesthesia the existence of a septo-hippocampal projection has been verified by the evoked potential method. Its origin is the magnocellular medial septal nucleus. These septo-fugal fibres activate the basal parts of the apical dendrites and/or the soma of the CAI neurons, probably by a mono-synaptic route. By repetitive stimulation and by strychnine the depolarized area of the CAI neurons may increase, by anoxia it may decrease. Thus, according to the excitability level, a smaller or greater part of the apical dendrites may initiate spikes of an all-or-none character.
