title: [Volumetric analysis of the principal subdivisions of the brain of Gobioidei (Teleosts, Perciformes)].
abstract: The coral reef Gobioidei have very small olfactory bulbs. Compared to other teleost fishes, Gobioidei are all microsmic. The forebrain shows little variation; its size is the same as that of other perciform fishes, giving a good idea of the phylogenetic level of the Gobioidei. The mesencephalic tectum is very important in Gobioidei but very small in Trypauchen vagina, which is a burrowing species that is almost blind. The cerebellar body is small as in all other benthic fishes. The cerebellar valvula is also always small, especially the reflex lamina. The medulla oblongata is very large; the size of the vagal and facial lobes is correlated with the gustatory sense, an important feature of most Gobioidei.
