Research has shown that on average, women tend to have a slightly larger corpus callosum than men (although there is a lot of individual variability). Therefore, it is most tenable to hypothesize that Ramona's corpus callosum may be slightly larger than Stefan's, but it would be unlikely to assume a large difference in brain size between the two individuals, as there is generally no significant difference in overall brain size between men and women.
