Single shock stimulations have been applied stereotaxically and bilaterally in the region of the caudo-thalamic groove of the cat. These stimulations elicit diphasic potentials in the amygdala. Using combined methods of stimulation and lesion, it has been demonstrated that these electrical responses are due to the excitation of fibers projecting rostrally in the lateral border of the contralateral fimbria and caudally in the homologous part of the homolateral fimbria. A commissural path has been identified in the rostral part of the fimbria-fornix. Analysis of the experimental data has shown that the projection system consists of a discrete bundle of fibers which probably reaches the amygdala directly, in the dorsal part of the basal nucleus. The length of the explored portion of this pathway has been measured. The calculated conduction velocity of this amygdalopetal commissural component of the fimbria is 4.5 m/sec.
已在猫的丘脑尾状沟区域进行了立体定向双侧单次电击刺激。这些刺激在杏仁核中引发双相电位。通过刺激和损伤相结合的方法，已证明这些电反应是由于对侧海马伞外侧边界向头侧投射以及同侧海马伞同源部分向尾侧投射的纤维兴奋所致。在穹窿海马伞的头侧部分已确定了一条连合通路。对实验数据的分析表明，投射系统由一束离散的纤维组成，这些纤维可能直接到达基底核背侧部分的杏仁核。已测量了该通路探索部分的长度。计算出的海马伞向杏仁核连合成分的传导速度为4.5米/秒。
