The nediodorsal thalamic nucleus (MD) afferents originating in the prefrontal cortex (PFC) were studied in 14 dogs, using the method of retrograde horseradish peroxidase transport. Injections limited to small areas of MD indicated that projection between MD and PFC shows precise topography and reciprocity. However, the distribution of labeled neurons suggests a division of MD into two main segments related to the corresponding projection zones in the prefrontal cortex. The medioventral PFC zone is specifically related to the medial MD segment, while the dorsolateral PFC zone is related to its lateral segment. Transitional areas located on the lateral and medial surfaces were identified between the two main cortical zones. They are connected with both lateral and medial segments of MD.
采用辣根过氧化物酶逆行运输法，在14只犬中研究了起源于前额叶皮质（PFC）的丘脑背内侧核（MD）传入纤维。局限于MD小区域的注射表明，MD与PFC之间的投射显示出精确的拓扑结构和相互性。然而，标记神经元的分布表明MD可分为两个主要节段，分别与前额叶皮质中的相应投射区相关。前额叶皮质的内侧腹侧区与MD的内侧节段特异性相关，而背外侧区与外侧节段相关。在两个主要皮质区之间确定了位于外侧和内侧表面的过渡区。它们与MD的外侧和内侧节段均相连。
