| 摘 要： | 用荧光金（ＦＧ）逆行束路追踪技术对１５只大鼠下丘传入纤维的中脑外起源进行了研究，将ＦＧ注入一侧下丘后，在下列核区内可见到ＦＧ标记细胞：双侧下橄榄核（ＩＯＭ）、外侧上橄榄核（ＬＳＯ）；双侧（以同侧为主）蓝斑（ＬＯＣ）、听皮质（ＡＣ）；同侧内侧膝状体（ＭＧ）、内侧上橄榄核（ＭＳＯ）、橄榄旁侧（ＳＰＮ）、斜方体腹侧核（ＶＴＢ）、未定带（ＺＩ）、穹窿周核（ＰＥＦ）；对侧蜗神经腹前核（ＡＶＣＮ）、蜗神经腹后核（ＰＶＣＮ）、蜗神经背侧核（ＤＣＮ）、斜方体外侧核（ＬＴＢ）、三叉神经脊束核（ＮＴＳＴ）。结果提示，下丘不仅是听觉传导路的重要中继核，而且可能是多种功能的整合中枢。

| Abstract: | The afferent fibrous origins of inferior colliculus from brain(out of midbrain)have been studied by using a retrograde tracing technique.After FG was injected into left inferior colliculus in rats,FG retrogradely labelled-cells were found in the following nuclei:bilateral inferior olive nucleus (IOM)and lateral superior olive nucleus(LSO);bilateral(mainly ipsilateral)locus ceruleus(LOC)and auditory cortex(AC);ipsilateral midial geniculate nucleus(MG);midial superior olive nucleus(MSO),superior paraolivary nucleus(SPN), ventral nucleus of the trapezoid body(VTB),zone incerta(ZI),peritornical nucleus(PEF);contralateral anterior ventral cochlear nucleus(AVCN),posterior ventral cochlear nucleus(PVCN),dorsal cochlear nucleus(DCN),lateral nucleus of the trapezoid body(LTB)and nucleus of the spinal tract of the trigeminal nerve(NTST). |
