Duration of task: an indicator of differentiation between motoneuron pools.
Sustaining an isometric contraction at a percentage of maximum contraction value prior to fatigue is significantly longer for the dominant arm than the non-dominant arm as reanalysis of data shows. This peripheral motor parameter which differentiates handedness as reflected in motoneuron pools may clarify the relationship between contralateral motor function and functional cerebral lateralizations.
