摘　　要：目的：探讨大鼠皮质下端脑到前额叶皮质的传入投射。方法：用ＦＧ（荧光金）逆行追踪法对１５只Ｗｉｓｔａｒ大鼠进行研究。结果：观察到同侧苍白（ＧＰ），杏仁复合体（Ｌａ、ｂｌａ），斜角带（ｖｄｂ、ｖｄｂｄ、ｖｄｂｖ、ｈｄｂ），无名质（ＳＩ）及双侧屏状核（Ｃｌ）发出纤维向前额叶外侧中央前区投射。由此可推测在锥体外系中存在这样一个环路：前额叶皮质→脑桥核→小脑皮质→齿状核→苍白球→前额叶皮质。结论：前额叶外侧中央前区在锥体外系活动、嗅—躯体活动。Objective: The afferent projection of the prefront cortex from the subcortical telencephalon was investigated Methods: Prefront cortex lateral precentral area was studied using FG technique in 15 Wistar rat Results: The afferent projection from the subcortical telencephalon mainly originate from the globus pallidus(GP), the amygdaloid nuclei:lateral amygdaloid nucleus(la), anterior division of the basolateral nucleus of the amygdala(bla),nucleus of the vertical limb of the diagonal band(vdb), nucleus of the vertical limb of the diagonal band, dorsal part(vdbd), nucleus of the vertical limb of the diagonal band, ventral part(vdbv), nucleus of the horizontal limb of the diagonal band(hdb),substantia innominata(SI), and bilateral claustrum(cl) It is also guessed that there could be a circular path:in the extrapyramidal system prefrontal cortex→pontile nucleus→cerebellar cortex→globus pallidus→prefrontal cortex Conclusion: The result indicates that prefrontal cortex lateral precentral area has integration during extrapyramidal system activating, smelling-somatic activating, smelling-visceral activating
