The perception of pain in others suppresses somatosensory oscillations: A magnetoencephalography study
2008
NeuroImage
Preserved Fulltext
Importantly, watching painful compared to nonpainful situations suppressed somatosensory oscillations to a significant stronger degree. ...
These results, consistent with the mirror-neuron system, demonstrate that the perception of pain in others modulates neural activity in primary somatosensory cortex and supports the idea that the perception ...

In this whole-head magnetoencephalography (MEG) study, we examined the neuronal mechanisms underlying the influence of emotional (fearful, angry, or happy) compared to neutral facial expressions on the ...
The presentation of faces with emotional expressions compared to faces with neutral expressions led to a stronger bilateral suppression of the pain-induced BBA, possibly reflecting enhanced response readiness ...
