The object of this work has been to show neuronal typology and stratification of the optic tectum in Gallotia galloti adult specimens so as to have a basic model for the neuronal genesis study. As methodology Nissl and Golgi-Stensaas technique were employed. Six strata have been identified that include 14 layers where the neuronal types can be included, poligonals, bipolar, monopolar and stellate types. The stratification of the optic tectum in the 14 layers is corroborated in Reptiles, a fact which is maintained in birds, and is reduced in amphibians, urodels, and fish here the reptil optic tectum presentes an extraordinary importance in the study of the auditive and visual vias in phylogeny.
