A Gross Morphometric Study of Olfactory Brain Components in the Rufous Sengi ( Elephantulus rufescens )
SUMMARY: The gross morphometric features of mammalian olfactory system components show variations that may be attributed to dietary and ecological factors. We analyzed volumes and linear dimensions of olfactory brain components (OBC) namely, olfactory bulb (OB), olfactory tract (OT) and olfactory st...

We analyzed volumes and linear dimensions of olfactory brain components (OBC) namely, olfactory bulb (OB), olfactory tract (OT) and olfactory stria (OS) in an Afrotherian insectivore, the rufous sengi. These findings were then compared with those obtained previously in dogs (carnivore), goats (herbivore) and humans (omnivore). Volumes, lengths and breadths of the OBC were compared with those of the cerebral hemisphere (CH) and the whole brain (WB) by working out their ratios (%). In the sengi, the volume of OBC: WB was 1.03 %, length of OBC: CH = 58.08 % and breadth of OB: CH = 28.97 %. In an earlier report by Kavoi & Jameela respective values for the above parameters were 0.03 %, 21.47 % & 8.94 % in humans, 0.77 %, 51.87 % & 29.73 % in goats and 1.95 %, 72.30 % & 42.91 % in dogs.
