Capuchin Monkey (Cebus apella) Telencephalon: Macroscopic Anatomic Study

Abstract

Comparative anatomy goes back to antiquity, since Aristotle (384-323 a.C.) already studied animals, emphasizing their anatomical forms and structural organization. The study of anatomical characteristics, mainly with comparative approach, also associates “modus vivendis” of individual or taxonomic group. In this sense, this paper purposes to study and describe macroscopic anatomy of Capuchin Monkey telencephalon, in view to knowledge about biology system of this animal, as an important faunal component of Cerrado biome. For this, one male and one female specimen of Capuchin Monkey were analyzed, obtained from accidental death on the roadsides of Brazilian Southeast of Goiás, under authorization of SISBIO nº 37072-2 and procedures conducted in accordance with ethical principles approved by Institutional Ethics in Research Committee of Federal University of Uberlândia (CEUA/UFU nº 067/12). Capuchin Monkey (Cebus apella) telencephalon is relatively large in relation to the size of this animal, with globose aspect and slightly long laterolaterally, narrowing abruptly in rostral sense. In general terms, it resembles human brain, however, presents little convolute and less number of sulcus and gyrus and less prominent giving somewhat lisencecephalic aspect.
