The topography and cytoarchitecture of nc. hypothalamicus ventromedialis, nc. hypothalamicus dorsomedialis and nc. infundibularis were descripted in the pig. The nc. hypothalamicus ventromedialis is the dominant nucleus in the tuber cinereum. The rostral pole lies caudal to the nc. hypothalamicus anterior. Its caudal pole is bounded by the nc. premamillaris and the nc. hypothalamicus ventrolateralis. Scattered neurons separate the nc. hypothalamicus ventromedialis dorsal from the nc. hypothalamicus dorsomedialis. Dorsolateral it is limited by the fornix and medial from the ventricular wall by the nc. hypothalamicus periventricularis ventralis and the nc. infundibularis. The neurons are medium-sized. They are compactly arranged at the periphery but in the centre the texture is much looser. The nc. hypothalamicus dorsomedialis is a poorly delimited nucleus in the rostral part of the medial hypothalamus. Ventral it is separated from the nc. hypothalamicus ventromedialis by a narrow relative cell free zone. The area hypothalamica rostralis limits it dorsolateral and the nc. paraventricularis dorsomedial. The caudal boundary is formed medial by the nc. periventricularis dorsalis and lateral by the fornix and the area hypothalamica lateralis. Small and medium-sized neurons predominate in this nucleus. The nc. infundibularis surrounds the infundibulum and reaches the recessus mamillaris. The two lateral parts are united at the floor of the third ventricle. Its small neurons are associated with the ependym. The topography and cytoarchitecture of the pig tuber cinereum was compared with the nuclear configuration of other Artiodactyla, Perissodactyla, Carnivora and Rodentia.
描述了猪下丘脑腹内侧核、下丘脑背内侧核和漏斗核的形态及细胞构筑。下丘脑腹内侧核是灰结节中的主要核团。其嘴侧极位于下丘脑前核的尾侧。尾侧极以乳头前核和下丘脑外侧核为界。散在的神经元将下丘脑腹内侧核背侧与下丘脑背内侧核分隔开。背外侧以穹窿为界，内侧以室壁的下丘脑室周腹侧核和漏斗核为界。神经元为中等大小。它们在外周紧密排列，但在中央质地则疏松得多。下丘脑背内侧核是下丘脑内侧部嘴侧部分界限不清的核团。腹侧通过狭窄的相对无细胞区与下丘脑腹内侧核分隔开。下丘脑嘴侧区在背外侧界定它，室旁背内侧核在背侧界定它。尾侧边界内侧由室周背侧核形成，外侧由穹窿和下丘脑外侧区形成。该核中以小和中等大小的神经元为主。漏斗核围绕漏斗并延伸至乳头体隐窝。两个外侧部分在第三脑室底部相连。其小神经元与室管膜相连。将猪灰结节的形态及细胞构筑与其他偶蹄目、奇蹄目、食肉目和啮齿目动物的核结构进行了比较。
