Relative brain size of some southern African myomorph rodents

Abstract

Relative brain sizes, based on actual measurement of the brains of nine species of myomorph rodents, two insectivores and a macroscelidid are reported. Relative brain sizes of the macroscelidid and Tatera leucogaster were far larger than those of the other rodents. With the exception of T. leucogaster, relative brain sizes were largest in semi-arboreal, omnivorous and nocturnal rodent species.
