将 HRP 注入视前区各核后在紧邻注射区前方的隔区各核中均未能找到标记细胞,丘脑下部外侧核中标记细胞也非常少,而在注入丘脑下部外侧核后却在隔区和视前区各核中见到较多的标记神经元。另有二例注射范围虽涉及穹窿,但海马中无标记细胞出现。结合以往关于隔区神经元发下行轴突参与内侧前脑束的组成及海马作为穹窿纤维的主要来源的证据,作者认为在不直接损伤纤维束的情况下过路纤维似乎不能摄取并向胞体逆行输送足量的 HRP,因而可以避免过路纤维对结果的干扰。
After HRP was injected into each nucleus of preoptic area, the labeled cells could not be found in all the nuclei in the anterior segment of the injection zone. The labeled cells in the lateral hypothalamic nucleus were also very few. However, after injected into the lateral thalamic nucleus, And preoptic area to see more nuclei in labeled neurons. Although there are two other cases involving the injection of fornix, there are no labeled cells in the hippocampus. In the past, evidence of the involvement of inferior axons in medial forebrain bundles and the main source of hippocampus as fornix fibers in isolated neurons of the septal area suggests that crossover fibers do not appear to be uptake and transport retrogradely to the soma without direct damage to the fiber bundle A sufficient amount of HRP thus avoids interfering with the result of crossover fibers.
