Crossed cerebral lateralization for verbal and visuo‐spatial function in a pair of handedness discordant monozygotic twins: MRI and fMRI brain imaging

[ TLDR ]

The twins were discordant for MRI anatomical asymmetries of the pars triangularis and planum temporale, whose asymmetry was consistent with verbal laterality on fMRI, and the right‐handed twin had right lateralized verbal with left lateralized visuo‐spatial activation; these data lend further support for to the conclusions of Sommer et al.
