Abstract

For this study, 10 brain of mongrel dogs, 5 males and 5 females, weighing between 8-12 Kg, with constitutionalist characteristics of cranium similar (mesaquicefalus), were collected. They were prepared according to conventional histological technique and stained by modified violet cresil, for becoming evident the neurons bodies. Through the morphometric analysis, comparative data were reached, mainly between the different bodies areas; brain right and left hemisphere and between the sex, for the knowledge of the arrangement and the quantity of the neuron bodies. The slides were analyzed with the aid of Axioscópio Zeiss®. The results showed that males had major quantity of the neuron bodies in brain right hemisphere (16,71). Once in females the rate were contrary, showing major quantity of neuron bodies in brain left hemisphere (17,46), when compared the different brain areas. The dogs showed major quantity of the neuron bodies in the visual area (19,77), following by the comportamental or limbic area (18,37) and between others areas did not show significant difference.
