Afferent subcortical connections to the medial prefrontal cortex (PFC) in the dog were investigated using the horseradish peroxidase retrograde transport method. The dorsal and ventral regions of the medial PFC receive different projections both from the mediodorsal and the ventral thalamic nuclei. The dorsomedial PFC receives projection from a dorsolateral region of the "parvocellular" MD subdivision, while the ventromedial PFC - from the medial, "magnocellular" MD subdivision. The area precruciata medialis (XM) is involved in significant MD projection and should be included in the "prefrontal" not the "premotor" cortex. The ventral thalamic nuclei project mainly to the dorsomedial but not the ventromedial cortex. The distribution of this projection was correlated with antero-posterior cortical localization of injections. The main criterion for distinguishing "prefrontal" and "motor" cortex remains its projections either from MD or from VL nuclei. Only the ventromedial prefrontal cortex receives projection from anterior thalamic nuclei. The caudal region of the ventromedial prefrontal cortex seems to receive richer projection from "non-specific" thalamic nuclei as well as from the amygdaloid complex.
采用辣根过氧化物酶逆行运输法研究了犬内侧前额叶皮质（PFC）的传入性皮质下连接。内侧PFC的背侧和腹侧区域分别接受来自背内侧丘脑核和腹侧丘脑核的不同投射。背内侧PFC接受来自“小细胞”MD亚区背外侧区域的投射，而腹内侧PFC则接受来自内侧“大细胞”MD亚区的投射。内侧前交叉区（XM）参与显著的MD投射，应归入“前额叶”皮质而非“运动前”皮质。腹侧丘脑核主要投射至背内侧皮质而非腹内侧皮质。该投射的分布与注射部位的前后皮质定位相关。区分“前额叶”和“运动”皮质的主要标准仍然是其来自MD核或VL核的投射。只有腹内侧前额叶皮质接受来自丘脑前核的投射。腹内侧前额叶皮质的尾侧区域似乎接受来自“非特异性”丘脑核以及杏仁复合体的更丰富投射。
