Lateralisation and inter-hemispheric connectivity. a Tractography of the corpus callosum in a representative subject of our study (top left); cortical projection of the corpus callosum derived from axonal tracing in monkeys31 (top right); cortical projections of the corpus callosum derived from tractography in the participants of our study (bottom). b Histogram of the difference between lateralised and non-lateralised regions in the corpus callosum axonal water fraction, averaged across participants. c Histogram of the difference between lateralised and non-lateralised regions in the corpus callosum probability of connection. The measure was calculated as the proportion of participants in which a connection exists between brain’s voxels and corpus callosum to the overall HCP sample size. d Dimensional relationship between the degree of functional lateralisation and the corpus callosum probability of connectivity.
