Neuronal morphology in the lateral geniculate nucleus of the porpoise (Phocoena phocoena).
The Golgi and Nissl methods and cytochrome oxidase (CO) histochemistry were used to study the overall structure and neuronal morphology of the lateral geniculate nucleus (LGN) of the Black Sea porpoise (Phocoena phocoena). Differences were observed between dorsal and ventral portions of the nucleus in terms of cell size and CO staining. In addition to prominent fibre bundles crossing the LGN horizontally, vertically oriented variations of CO staining were apparent. Neuronal types in the LGN corresponded broadly to those observed in land mammals. The commonest were variants of multipolar cells, and may represent thalamocortical relay cells. Various other types were probably interneuronal.
