Neuromagnetic brain activity associated with anticipatory postural adjustments for bimanual load lifting

► APA is associated with premovement desynchronization of the cortical beta rhythm. ► Beamformers localize activity to the precentral gyrus and supplementary motor area. ► Subcortical activations are found in the basal ganglia and thalamus. ► All sources are lateralized to the hemisphere contralateral to the load-bearing arm.
