用荧光逆行示踪双标记法观察了大鼠杏仁核和海马神经元经轴突侧支投射到内侧前额叶皮质和下丘脑的情况。将荧光金注射到内侧前额叶皮质，而将荧光红注射到下丘脑的腹内侧和腹侧乳头体前核。结果表明，在杏仁-海马过渡区或CAI中，向内侧前额叶皮质和下丘脑发送轴突侧支的神经元分别占内侧前额叶皮质投射神经元的50%或30%。并对轴突侧支神经元在性攻击和/或防御行为中的可能作用进行了讨论。(C)2000 Elsevier Science爱尔兰有限公司和日本神经科学学会。All rights reserved.
Amygdaloid and hippocampal neurons projecting to both the medial prefrontal cortex and hypothalamus by way of axon collaterals were examined in the rat by double labeling method using fluorescence retrograde tracers. Fluoro-gold was injected in the medial prefrontal cortex, while Fluoro-red was injected into the ventromedial and ventral premammillary nuclei of the hypothalamus. The results indicated that neurons which sent axon collaterals to both the medial prefrontal cortex and hypo thalamus constituted 50 or 30% of populations of medial prefrontal cortex-projecting neurons in the amygdalo-hippocampal transition area or in CAI, respectively. Possible roles of the neurons with axon collaterals in sexually related aggressive and/or defensive behavior were discussed. (C) 2000 Elsevier Science Ireland Ltd and the Japan Neuroscience Society.
