The subcortical afferents of the mediodorsal thalamic nucleus (MD) were studied using the method of retrograde horseradish peroxidase transport. Analysis of the distribution of labeled cells following injections into particular MD segments established specific and unspecific projections originating in various subcortical structures. The medial MD segment is related to such structures of the limbic system as: the anterior olfactory nucleus, olfactory tubercle, nucleus of diagonal band, arnygdala and septum, whereas the lateral MD segment receives afferentation from such structures involved in motor activity regulation as: the substantia nigra, entopeduncular nucleus, and cerebellar nuclei.Moreover, this segment is connected with the structure of the primary visual system, the lateral geniculate body. Nonspecific projections terminating in the entire MD nucleus originate in numerous structures at different CNS levels. The hypothalamus and reticular thalamic nucleus seem to have the strongest relationship with MD.
采用辣根过氧化物酶逆行运输法研究了丘脑背内侧核（MD）的皮质下传入纤维。通过向特定MD节段注射后对标记细胞分布的分析，确定了源自各种皮质下结构的特异性和非特异性投射。MD内侧节段与边缘系统的以下结构相关：前嗅核、嗅结节、斜角带核、杏仁核和隔区，而MD外侧节段则接受参与运动活动调节的以下结构的传入：黑质、脚内核和小脑核。此外，该节段与初级视觉系统的结构外侧膝状体相连。终止于整个MD核的非特异性投射起源于中枢神经系统不同水平的众多结构。下丘脑和丘脑网状核似乎与MD的关系最为密切。
