Background. Recent neuroscientific evidence suggests that empathy for pain activates similar neural representations as the first-hand experience of pain. However, empathy is not an all-or-none phenomenon but it is strongly malleable by interpersonal, intrapersonal and situational factors. This study investigated how two different top-down mechanisms – attention and cognitive appraisal - affect the perception of pain in others and its neural underpinnings. Methodology/ Principal Findings. We performed one behavioral (N = 23) and two functional magnetic resonance imaging (fMRI) experiments (N = 18). In the first fMRI experiment, participants watched photographs displaying painful needle injections, and were asked to evaluate either the sensory or the affective consequences of these injections. The role of cognitive appraisal was examined in a second fMRI experiment in which participants watched injections that only appeared to be painful as they were performed on an anesthetized hand. Perceiving pain in others activated the affective-motivational and sensory-discriminative aspects of the pain matrix. Activity in the somatosensory areas was specifically enhanced when participants evaluated the sensory consequences of pain. Perceiving non-painful injections into the anesthetized hand also led to signal increase in large parts of the pain matrix, suggesting an automatic affective response to the putatively harmful stimulus. This automatic response was modulated by areas involved in self/other distinction and valence attribution – including the temporo-parietal junction and medial orbitofrontal cortex. Conclusions/Significance. Our findings elucidate how top-down control mechanisms and automatic bottom-up processes interact to generate and modulate other-oriented responses. They stress the role of cognitive processing in empathy, and shed light on how emotional and bodily awareness enable us to evaluate the sensory and affective states of others.
Hearing others’ pain: neural activity related to empathy
Cognitive, Affective, & Behavioral Neuroscience, 2011
The human voice is one of the principal conveyers of social and affective communication. Recent neuroimaging studies have suggested that observing pain in others activates neural representations similar to those from the first-hand experience of pain; however, studies on pain expressions in the auditory channel are lacking. We conducted a functional magnetic resonance imaging study to examine brain responses to emotional exclamations of others' pain. The control condition comprised positive (e.g., laughing) or negative (e.g., snoring) stimuli of the human voice that were not associated with pain and suffering. Compared to these control stimuli, pain-related exclamations elicited increased activation in the superior and middle temporal gyri, left insula, secondary somatosensory cortices, thalamus, and right cerebellum, as well as deactivation in the anterior cingulate cortex. The left anterior insular and thalamic activations correlated significantly with the Empathic Concern subscale of the Interpersonal Reactivity Index. Thus, the brain regions involved in hearing others' pain are similar to those activated in the empathic processing of visual stimuli. Additionally, the findings emphasise the modulating role of interindividual differences in affective empathy.
Dispositional empathy predicts primary somatosensory cortex activity while receiving touch by a hand
Scientific Reports
Previous research revealed an active network of brain areas such as insula and anterior cingulate cortex when witnessing somebody else in pain and feeling empathy. But numerous studies also suggested a role of the somatosensory cortices for state and trait empathy. While recent studies highlight the role of the observer’s primary somatosensory cortex when seeing painful or nonpainful touch, the interaction of somatosensory cortex activity with empathy when receiving touch on the own body is unknown. The current study examines the relationship of touch related somatosensory cortex activity with dispositional empathy by employing an fMRI approach. Participants were touched on the palm of the hand either by the hand of an experimenter or by a rubber hand. We found that the BOLD responses in the primary somatosensory cortex were associated with empathy personality traits personal distress and perspective taking. This relationship was observed when participants were touched both with the...

The purpose of the present study was to assess the relationship between brain metabolism and empathic response. Six right-handed healthy volunteers were scanned with PETand fluorodeoxyglucose twice: during an interview about neutral story themes and during an empathic response eliciting interview about a story of a character in distress. Metabolic values in the medial and superior frontal gyrus, occipitotemporal cortices, thalamus and the cerebellum were higher during empathic response than during the neutral theme interview. Furthermore, the subjects' empathy scores were positively correlated with metabolism in the medial aspects of the superior frontal gyrus. Our results suggest that empathy consists of both affective and cognitive components and hence may involve cortices that mediate simulation of emotional processing and mental state attribution. D

Perspective-taking is a stepping stone to human empathy. When empathizing with another individual, one can imagine how the other perceives the situation and feels as a result. To what extent does imagining the other differs from imagining oneself in similar painful situations? In this functional magnetic resonance imaging experiment, participants were shown pictures of people with their hands or feet in painful or non-painful situations and instructed to imagine and rate the level of pain perceived from different perspectives. Both the Self's and the Other's perspectives were associated with activation in the neural network involved in pain processing, including the parietal operculum, anterior cingulate cortex (ACC; BA32) and anterior insula. However, the Self-perspective yielded higher pain ratings and involved the pain matrix more extensively in the secondary somatosensory cortex, the ACC (BA 24a /24b ), and the insula proper. Adopting the perspective of the Other was associated with specific increase in the posterior cingulate/precuneus and the right temporo-parietal junction. These results show the similarities between Self-and Other-pain representation, but most interestingly they also highlight some distinctiveness between these two representations, which is a crucial aspect of human empathy. It may be what allows us to distinguish empathic responses to others versus our own personal distress. These findings are consistent with the view that empathy does not involve a complete Self-Other merging. (J. Decety).

Background Empathy for pain is a complex phenomenon incorporating sensory, cognitive and affective processes. Functional neuroimaging studies indicate a rich network of brain activations for empathic processing. However, previous research focused on core activations in bilateral anterior insula (AI) and anterior cingulate/anterior midcingulate cortex (ACC/aMCC) which are also typically present during nociceptive (pain) processing. Theoretical understanding of empathy would benefit from empirical investigation of shared and contrasting brain activations for empathic and nociceptive processing. Method Thirty-nine empathy for observed pain studies (1112 participants; 527 foci) were selected by systematic review. Coordinate based meta-analysis (activation likelihood estimation) was performed and novel contrast analyses compared neurobiological processing of empathy with a comprehensive meta-analysis of 180 studies of nociceptive processing (Tanasescu et al., 2016). Results Conjunction a...

Humans observe various peoples social suffering throughout their lives, but it is unknown whether the same brain mechanisms respond to people we are close to and strangers social suffering. To address this question, we had participants complete functional magnetic resonance imaging (fMRI) while observing a friend and stranger experience social exclusion. Observing a friends exclusion activated affective pain regions associated with the direct (i.e. firsthand) experience of exclusion [dorsal anterior cingulate cortex (dACC) and insula], and this activation correlated with self-reported self-other overlap with the friend. Alternatively, observing a strangers exclusion activated regions associated with thinking about the traits, mental states and intentions of others [mentalizing; dorsal medial prefrontal cortex (DMPFC), precuneus, and temporal pole]. Comparing activation from observing friends vs strangers exclusion showed increased activation in brain regions associated with the firsthand experience of exclusion (dACC and anterior insula) and with thinking about the self [medial prefrontal cortex (MPFC)]. Finally, functional connectivity analyses demonstrated that MPFC and affective pain regions activated in concert during empathy for friends, but not strangers. These results suggest empathy for friends social suffering relies on emotion sharing and self-processing mechanisms, whereas empathy for strangers social suffering may rely more heavily on mentalizing systems.
I feel your pain: Higher empathy is associated with higher posterior default mode network activity
Empathy is characterized as the ability to share one’s experience. Recent findings indicate that the anterior mid-cingulate cortex (aMCC) and insular cortices play a role in empathy. For example, insular lesions lead to less empathetic behaviors. Further, neuroimaging studies revealed that viewing and/or mentalizing one’s romantic partner in pain produces higher aMCC and anterior insula activation. Said studies employed blood oxygen level dependent fMRI that may be less sensitive to comprehensively capture tonic empathetic responses to pain. Others have found that empathy for pain can elucidate self-other processing in pain-related brain regions (thalamus; somatosensory cortices). The present study investigated the differential neural empathetic responses elicited by viewing, in real-time, a female volunteer’s romantic partner (≥ 3 months) as compared to a stranger (laboratory technician) receive pain-evoking noxious heat during arterial spin labeling (ASL) fMRI acquisition. Based o...
An fMRI investigation of empathy for ‘social pain’ and subsequent prosocial behavior
Despite empathy's importance for promoting social interactions, neuroimaging research has largely overlooked empathy during social experiences. Here, we examined neural activity during empathy for social exclusion and assessed how empathy-related neural processes might relate to subsequent prosocial behavior toward the excluded victim. During an fMRI scan, participants observed one person being excluded by two others, and afterwards sent emails to each of these 'people.' Later, a group of raters assessed how prosocial (e.g., helpful, comforting) the emails were. Observing exclusion (vs. inclusion) activated regions associated with mentalizing (dorsomedial prefrontal cortex, medial prefrontal cortex, precuneus), and highly empathic individuals activated both mentalizing regions and social pain-related regions (anterior insula, dorsal anterior cingulate cortex). Additionally, the empathy-related activity in the anterior insula and medial prefrontal cortex was associated with later prosocial behavior toward the victim, and exploratory mediation analyses indicated that medial prefrontal cortex activity, in particular, may support the link between trait empathy and prosocial behavior. Overall, findings suggest that empathy-related neural responses to social experiences may promote spontaneous prosocial treatment of those in need.
