Event-Related Potentials for different groups associated to: a) standard stimuli, b) target stimuli, and c) valid and invalid cues for target stimuli period for three groups in different scalp positions. In the right column the period (black lines) where the LN was analyzed and the voltage maps for difference waveform are showed. The black arrow demonstrates when the imperative stimulus is presented.
