胼胝体纤维成分的分析表明，大脑半球间的传输时间可能会限制大脑半球间同步合奏的发展，特别是在像人类这样的大脑较大的物种中。为了克服这一限制，一个大直径的胼胝体纤维的子集专门用于快速的半球间传输，特别是在大脑物种。然而，在大脑大的物种中，大脑半球间的快速通讯受到限制，这在某种程度上有助于同侧半球内网络的发展，这可能会促进大脑侧化的发展。
Analysis of corpus callosum fiber composition reveals that inter-hemispheric transmission time may put constraints on the development of inter-hemispheric synchronic ensembles, especially in species with large brains like humans. In order to overcome this limitation, a subset of large-diameter callosal fibers are specialized for fast interhemispheric transmission, particularly in large-brained species. Nevertheless, the constraints on fast interhemispheric communication in large-brained species can somehow contribute to the development of ipsilateral, intrahemispheric networks, which might promote the development of brain lateralization.
