The paper associates left-handedness with structural brain asymmetries in specific cortical regions using data from 31,864 individuals and identifies genetic links to these asymmetries.

Characterization of late structural maturation with a neuroanatomical marker that considers both cortical thickness and intracortical myelination

Sophie Maingault, Antonietta Pepe, Bernard M. Mazoyer, Nathalie Tzourio‐Mazoyer, Fabrice Crivello

The paper introduces a new cortical maturation index (MATUR) based on the ratio of cortical thickness and intracortical myelination, showing it better captures age-related structural changes in adulthood than either measure alone.
