Furthermore, after accounting for body size, we find preliminary evidence that morphological evolution beyond allometry can correlate with hearing sensitivity...

However, notably, the olfactory bulbs and cerebellum scaled hyperallometrically to the rest of the brain, whereby these structures enlarged disproportionately as this species matured. Changes...

This suggests that allometry cannot explain all of the inter-individual variation in our quantitative measurements of the cerebellum and that factors other than cerebellum size are related to Purkinje cell size and CFI. Intra- or interspecific allometry of Purkinje cell numbers...

To reexamine these questions across a wider range of mammalian radiations, data on the primarily fetal rapid growth phase (RGP) of ontogenetic brain-body allometry was compiled for diverse primate (n p = 12) and nonprimate (n np = 16) mammalian species, and was complemented by later ontogenetic data in 16...
