sentences:  A paper published in Science (Singer et al., 2005) challenges the idea that pain sensations and mirror neurons play a role in empathy for pain.Specifically, the authors found that activity in the anterior insula and the anterior cingulate cortex was present both when one's self and another person were presented with a painful stimulus, two regions known to be responsible for the affective experience of pain, but the rest of the pain matrix, responsible for sensation, was not active.Furthermore, participants merely saw the hand of another person with the electrode on it, making it unlikely that 'mirroring' could have caused the empathic response.
