Thalamic projections to parietal regions of cerebral cortex were investigated in the cat by retrograde degeneration and retrograde transport techniques. Studies of retrograde cellular changes indicate cortically projecting cells in the lateroporterior nucleus (LP), rostral pulvinar (Pul), and the ventral part of the laterodorsal nucleus (LD). When lesions were placed in the cortex of young kittens, clear chromatolytic changes and cell loss were also consistently observed in middle and caudal parts of the ventroanterior nucleus (VA). Investigations of retrograde transport following intracortical injections of horseradish peroxidase have confirmed the results of retrograde degeneration studies by demonstrating cortically projecting cells in VA, LP, LD, and Pul. Retrograde transport studies also indicate cortically projecting cells in the central lateral nucleus. Material from both experimental techniques demonstrates a loose topographic organization of the projections from the lateral thalamus. Anterior parts of LP project to the anterior lateral gyrus and anterior middle suprasylvian gyrus. Middle LP and rostral Pul project to the middle suprasylvian gyrus.
运用逆行性变性和逆行性运输技术，对猫丘脑向大脑皮质顶叶区域的投射进行了研究。逆行性细胞变化研究表明，皮质投射细胞位于丘脑后外侧核（LP）、丘脑前结节（Pul）和丘脑背外侧核腹侧部（LD）。当在幼小猫的皮质中造成损伤时，在前腹侧核（VA）的中部和尾部也始终观察到明显的染色质溶解变化和细胞丢失。在皮质内注射辣根过氧化物酶后进行的逆行性运输研究，通过证实VA、LP、LD和Pul中的皮质投射细胞，证实了逆行性变性研究的结果。逆行性运输研究还表明，中央外侧核中存在皮质投射细胞。两种实验技术的材料均显示，丘脑外侧投射存在松散的拓扑组织。LP的前部投射至外侧前回和上薛氏前中回。LP中部和Pul前部投射至上薛氏中回。
