Delineation of midbrain regions connected with the motor cortex may be useful in evaluating disruptions of motor pathways in paediatric patients. We used the established winner-takes-it-all method to parcellate the midbrain according to cortical connectivity in healthy children aged 6-12 years. The percentage of ipsilateral midbrain occupied by motor parcels was negatively associated with age on the right side only, producing an association between age and interhemispheric asymmetry. Our findings indicate that age and interhemispheric differences need to be taken into account if this method is to be utilised for quantitative comparisons of midbrain-motor connectivity in children.
