Attention-related brain activations (rare minus frequent responses) in the control group derived from the VESTAL method. a Left-hemisphere activation, evoked by contralateral median-nerve stimulation of the right arm. b Left-hemisphere activation, evoked by ipsilateral stimulation of the left arm. c Right-hemisphere activation, evoked by contralateral stimulation of the left arm. d Right-hemisphere activation, evoked by ipsilateral stimulation of the right arm. FWER was controlled at P = .01 level
