[Evolutive morphology of the olfactory bulb in man and certain non-human mammals].

Human and comparative anatomy of the olfactory lobe and the anterior floor was studied in 241 patients and 27 specimens (2 human fetuses, 4 specimens from adult humans, 11 non human primates and 10 carnivorous mammals). Macroscopic morphology and imaging data (CT-scan, 3D) reconstruction and magnetic resonance imaging) were obtained at the same time. The results obtained provide radiographic knowledge of the olfactory bulb ontogenesis and a basis for recognizing inborn or acquired pathology of the olfactory bulb. Evidence was also obtained for distinguishing between macrosmatic and microsmatic criteria in mammals.
