Abstract

The gross anatomy and the internal morphology of the brainstem of the monkey Cebus apella were described based on the observations made on adult brainstens. Six adult Cebus apella monkeys were used for anatomical observations and for the study of the internal morphology they were cut into serial sections at six different levels (pyramidal decussation; superior portion of the olive; inferior portion of the olive; pons; superior colliculus and inferior colliculus) and properly stained for studies of the internal structure. Our results show that the Cebus apella brainstem is characterized by the presence of a bulbpontine sulcus; an enlarged brainstem, particularly of the medulla oblongata, with a consequent laterization of the trapezoid body, the presence of inferior olivary complex, the apparent origin of cranial nerves distant from the pyramids and of its decussation; presence of the antero-lateral sulcus separating the pyramids of the olives; expressive development of the trapezoid body, of the pons, nuclei of the pons and of the cerebral peduncle. These results are consistent with previous descriptions for other primates and suggest that the organization and development of the Brainstem structures share similarities with superior primates including humans which reflect the motor abilities of the studied species.
