Cortical projections of the medial geniculate body have been studied in dolphin Phocaena phocaena by the method of anterograde degeneration of Fink--Heimer. For this purpose, in two animals a unilateral electrocoagulation of the thalamic auditory center has been performed. The caudal part of the microcellular nucleus of the medial-geniculate body has been stated to project ipsilaterally on the parietal, parietooccipital and temporal cortex. The oral part of this nucleus sends its fibres to the parietal and parietooccipital cortex. In the parietooccipital and temporal cortex auditory thalamic afferent fibres terminate predominantely in the layer III and in the upper third of the layer I. In the parietal cortex they terminate evenly in all the layers.
采用芬克-海默顺行性变性法，对江豚的内侧膝状体皮质投射进行了研究。为此，对两只动物的丘脑听觉中枢进行了单侧电凝。内侧膝状体小细胞核的尾部被认为同侧投射到顶叶、顶枕叶和颞叶皮质。该核的口部将其纤维发送到顶叶和顶枕叶皮质。在顶枕叶和颞叶皮质，听觉丘脑传入纤维主要终止于第III层和第I层上三分之一处。在顶叶皮质，它们均匀地终止于所有层。
