Cytoarchitecture and ultrastructural characteristics of the area octavolateralis of the urodele amphibian Pleurodeles waltlii.
The cytoarchitecture of the area octavolateralis (AOL) in Pleurodeles waltlii is studied by means of normal stained material. In addition, the main ultrastructural features of the cells in the AOL are described. In the AOL, three columns, one upon the other (dorsal, intermediate and ventral), are present. Each one includes a medially located cell group and lateral neuropil. While rostrally the three are well represented, the dorsal subdivision do not reach the same caudal extent where the intermediate column forms a small lobe. The ultrastructure of the neurons in the AOL reveals similarities with other cell types in the amphibian brain. A comparative analysis of the ultrastructure of vestibular cells with other vertebrates is also discussed.
