将WGA-HRP微电泳导入19只大鼠的丘脑背内侧核(DM),又将WGA-HRP注射于17只大鼠前额叶皮质的前扣带回背部,前边缘叶和岛叶无颗粒皮质背部,观察DM的传出投射。 DM投射到前额叶皮质的范围广泛,并有一定的局部定位。DM外侧部主要投射到前扣带回背部,其次为中央前区内侧皮质、前边缘叶、岛叶无颗粒皮质背部及腹外侧眶区等。DM内侧部主要投射到岛叶无颗粒皮质背部,其次为前边缘叶、下边缘叶、内侧眶区及腹侧眶区等。DM中间部主要投射到岛叶无颗粒皮质背部。 DM还投射到某些皮质下核团,如丘脑网状核、外侧视前区、尾壳核、伏隔核、苍白球、丘脑下部外侧区及束旁核等。此外,DM和前额叶皮质的前扣带回背部、中央前区内侧皮质、前边缘叶、下边缘叶及岛叶无颗粒皮质背部以及和丘脑网状核、外侧视前区及丘脑下部外侧区之间均有交互投射。
The WGA-HRP microelectrophoresis was introduced into the dorsal medial nucleus of thalamus of 19 rats. WGA-HRP was injected into the anterior cingulate of 17 rat prefrontal cortex and the anterior cingulate and insular cortical cortex Back, observe the outgoing projection of DM. DM casts a wide range of prefrontal cortex, and has some local positioning. The outer part of the DM mainly projects into the anterior cingulate back, followed by the medial frontal cortex, the anterior margin leaf, the apex of the insular cortex and the ventral lateral ventricle. The medial part of DM is mainly projected to the granular cortical dorsal island, followed by the anterior margin leaf, lower margin leaf, medial orbital area and ventral orbital area. The DM middle section is mainly projected onto the insular leafless cortical back. DM is also projected onto certain subcortical nuclei, such as the thalamic reticular nucleus, lateral preoptic area, caudate putamen, nucleus accumbens, globus pallidus, lateral hypothalamic area and parafascicular nucleus. In addition, the dorsal anterior cingulate gyrus of DM and prefrontal cortex, medial anteromedial cortex, anterior margin leaf, inferior margin leaf and island leaflet cortexless dorsal and thalamic reticular nucleus, lateral preoptic area and lateral hypothalamic area Have interactive projection between.
