[Cortical projections of the medial geniculate body of the dolphin brain].
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.
