Abstract: Abstract Sultan's observations do not contradict our finding that, when normalized to the whole brain, cerebellar volume is relatively constant. To make interspecies comparisons, we used the volume fraction (the volume of a component divided by the total brain volume)1. Without this normalization, the dominant trend is variation in absolute size2. This logic applies to surface areas as well, and Sultan's interesting analysis reflects this principle.
