However , the temporal dynamics of neural activities underlying empathic processes remains poorly understood . This was investigated in the current study by recording event - related brain potentials (ERPs) from healthy adults who were presented with pictures or cartoons of hands that were in painful or neutral situations . Subjects performed a pain judgment task that required attention to pain cues in the stimuli or a counting task that withdrew their attention from these cues . The ERP results showed early differentiation between painful and neutral stimuli over the frontal lobe at 140 ms after sensory stimulation . A long - latency empathic response was observed after 380 ms over the central – parietal regions and was more salient over the left than right hemispheres . The early and late empathic responses were , respectively , modulated by contextual reality of stimuli and by top - down attention to the pain cues . Moreover , the mean ERP amplitudes at 140 – 180 ms were correlated with subjective reports of the degree of perceived pain of others and of self - unpleasantness . The ERP results support a model of empathy for pain consisting of early emotional sharing and late cognitive evaluation .
