Neurogenesis in the olfactory sytem of the brushtail possum Trichosurus vulpecula.

Abstract

A series of developmental studies of the brushtail possum (Trichosurus vulpecula) have described much of the postnatal neurogenesis in the brain of this species (Sanderson and Aitkin 1990; Sanderson and Weller 1990a,b; Harman et al. 1992; Sanderson and Wilson 1997) except in the olfactory system. The olfactory epithelium is well developed at birth (Hall and Hughes 1987). This study provides a brief report of neuronal birth in the olfactory system, using the same anatomical material from the previous studies.
