本研究将 WGA-HRP 注射于25只大鼠前额叶皮质的前扣带回背部、前边缘区及岛叶无颗粒皮质背部,观察其间脑和皮质下端脑的传入联系。间脑的传入主要来自丘脑背内侧核,并有一定的局部定位。此外,丘脑的板内核群(中央外侧核、旁中央核、中央内侧核及束旁核)、腹侧核群(腹外侧核、腹内侧核、腹前核及腹后核)、中线核群(菱形核、连合核、带旁核及室旁核)、前内侧核、外侧缰核、后核及外侧核亦有到前额叶皮质的传入投射,且投射到前额叶皮质不同部位的数量不同。丘脑下部的传入主要来自外侧区、外侧视前区、尾侧大细胞核及乳头体上核,少量传入也可见于丘脑下部后区、背内侧核、腹内侧核及未定带。皮质下端脑的传入主要来自苍白球,其次为斜角带核、隔核、杏仁核及屏状核。在隔核中,除内侧隔核外还观察到外侧隔核,繖隔核及三角隔核亦投射到前额叶皮质。杏仁核中除杏仁外侧核、杏仁基底核外侧部及内侧部外,还观察到杏仁内侧核及杏仁皮质核亦有少量到前额叶皮质的传入。
In this study, WGA-HRP was injected into the anterior cingulate cortex of 25 rat prefrontal cortex back to the anterior marginal zone and the island cotous cortex back to observe the afferent contact between the brain and the cortical lower brain. Intermittent afferent mainly from the medial dorsal thalamic nucleus, and have some local positioning. In addition, the thalamic platelet nuclei (central lateral nucleus, para-central nucleus, medial medial nucleus and parafascicular nucleus), ventral nuclear group (ventral lateral nucleus, ventral medial nucleus, ventral nucleus and posterior nucleus) (Rhombic nucleus, commissural nucleus, paraventricular nucleus and paraventricular nucleus), the anteromedial nucleus, lateral habenular nucleus, posterior nucleus and lateral nucleus also have the afferent projection to the prefrontal cortex, and projected to different parts of the prefrontal cortex The number is different. Subthalamic afferent mainly from the lateral area, lateral preoptic area, caudal large nuclei and papillary body nucleus, a small amount of afferent can also be found in the posterior thalamus, dorsal medial nucleus, ventral medial nucleus and undetermined band. Subclavian brain afferent mainly from the globus pallidus, followed by the angular nucleus, septal nucleus, amygdala and the screen-like nucleus. In the septum, the lateral septum is observed in addition to the septal septum. The septal and septal nuclei also project to the prefrontal cortex. In the amygdala, in addition to the almond nucleus, the lateral part and the medial part of the almond nucleus, a small amount of afferent to the prefrontal cortex is also observed in the medial almond and almond cortex nuclei.
