目的:探讨间脑中神经核向前额叶中央外侧区的投射.方法:用荧光金(FG)逆行追踪法对15只Wistar大鼠进行研究.结果:大鼠前额叶中央外侧区接受同侧丘脑前内侧核,丘脑前腹核;丘脑腹内侧核,丘脑腹外侧核,丘脑腹后内侧核,丘脑腹后外侧核;丘脑内侧背核中间部、外侧部、内侧部,丘脑外侧背核;丘脑后核,丘脑外侧后核;丘脑板内核的中央内侧核,中央旁核,中央外侧核,丘脑束旁核;丘脑中线核的丘脑带旁核,丘脑菱形核,丘脑连结核,丘脑室旁核;丘脑网状核,膝上核;下丘脑的室旁核,室周核,下丘脑后区,下丘脑外侧区,乳头体上核,乳头体内侧核.下丘脑外侧大细胞核,外侧视前区,内侧视前区及丘脑底部中的未定带,Forel区,丘脑底核的投射纤维.结论:前额叶中央外侧区接受广泛的间脑核团的投射,并存在着局部定位的关系.
Objective: To investigate the projection of the nucleus in the diencephalon to the lateral frontal area of the prefrontal cortex.Methods: Fifteen Wistar rats were studied by fluorescent gold (FG) retrograde tracing method.Results: The medial prefrontal cortex Ventral medial thalamic nucleus, ventral thalamic nucleus, thalamic ventral medial nucleus, thalamic ventral posterior lateral nucleus; medial dorsal thalamic nucleus, lateral portion, medial portion, dorsal thalamic nucleus; thalamus Posterior nucleus, lateral thalamic nucleus; central medial nucleus of thalamic nucleus, central para-nucleus, central lateral nucleus, parafascicular paraventricular nucleus; thalamic parafascicular nucleus, thalamic rhombic nucleus, thalamic nucleus, ; Hypothalamic paraventricular nucleus, periventricular nucleus, hypothalamic posterior region, hypothalamic lateral region, papillary nucleus, lateral papillary body nucleus. Lateral hypothalamic large nucleus, lateral visualization Region, medial preoptic area and hypothalamus undetermined zone, Forel area, subthalamic nucleus projection fiber.Conclusion: The lateral frontal area receives a wide range of projection of the mesencephalic nucleus, and there is a relationship between the local localization.
