Environmental and biological studies

Through Comparative Anatomy, it is possible to compare and relate the form and function of anatomical structures, not yet described, with those already well established in other species.Therefore, the aim of this research is the study of macroscopic anatomical organization of the Telencephalon of maned wolf, neotropical canid, wildlife component of the Brazilian cerrado.In this study two adult specimens, males, were dissected and analyzed, which were collected dead on the highways of the southeast of the state of Goiás.(SISBIO 37072/2).The data are described and compared with those of literature, already well established, of dog.In relation to the animal's size the Telencephalon of the maned wolf is relatively small and exhibits a caudal pole quite rounded and full of well-defined sulci and gyri, also, presents a rostral pole slightly tapered, which gives the hemisphere a form of chickpea (Cicer arietinum) flattened dorsoventrally.This characteristic suggests an increased cortical development of the rostral half-brain of the maned wolf, in relation to the dog.Furthermore, consists of two parts or Cerebral Hemispheres, separated by a deep Longitudinal Fissure.The surface of each hemisphere is marked by sulci and gyri, similar to what is described in the dog, however, possibly due to lower development of the cortex in this canid, some sulci and gyri were not found.Thus, although fewer in number, are present in the maned wolf, occupying sites and similar positions: Rhinal Sulcus; Sylvian Sulcus;
