Resumen:
  The most salient neuroanatomical features of the brain of the seven banded armadillo Dasypus hybridus are described. The microscopic characteristics were studied by serial transverse and sagittal paraffin sections, stained with Nissl and Klüver-Barrera technique. This analysis comprises the telencephalon, diencephalons and mesencephalon. The most outstanding features of this brain are: 1)      Great development of rhinencephalic structures (olfactory bulbs, olfactory tubercles, anterior commissure and pyriform cortex). 2)      The relative size of the induseum griseum strongly suggests that this animal would be useful for a variety of studies on this structure. 3)      The high position of the rhinal fissure on the lateral hemispheric wall determines the smallness of neocortex. Therefore, this armadillo is also useful for decortication studies. 4)      Absence of a distinct pineal organ. 5)      Conspicuous subfornical and subcommissural organs. 6)      Absence of a distinct intermediate lobe in the hypophysis.
