Previous studies have shown a shared neural circuitry in the somatosensory cortices for the experience of one's own body being touched and the sight of intentional touch. Using functional magnetic resonance imaging (fMRI), the present study aimed to elucidate whether the activation of a visuotactile mirroring mechanism during touch observation applies to the sight of any touch, that is, whether it is independent of the intentionality of observed touching agent. During fMRI scanning, healthy… 
Functional and structural brain differences associated with mirror-touch synaesthesia
Effects of different viewing perspectives on somatosensory activations during observation of touch
TLDR
Results showed activation of somatosensory cortices when observing the hand being touched in egocentric as well as in the allocentric perspectives, and somatoensory responses differed depending on the perspective of the observed touch.
Mirror touch : electrophysiological and behavioural evidence on the effects of observing others' tactile sensations on somatosensory processing in the observer and possible links to trait empathy
TLDR
A highly complex pattern of correlations between the strength of touch observation-related ERP modulations and interindividual differences in trait empathy associated the automatic sharing of others’ bodily states with complex emotional and cognitive empathy phenomena.
Differential Involvement of Somatosensory and Interoceptive Cortices during the Observation of Affective Touch
Previous studies suggested that the observation of other individuals' somatosensory experiences also activates brain circuits processing one's own somatosensory experiences. However, it is unclear
Touch to see: neuropsychological evidence of a sensory mirror system for touch.
TLDR
The causal interplay between observed and felt touch in right brain-damaged patients is investigated, as a function of their underlying damaged visual and/or tactile modalities.
Close to You: Embodied Simulation for Peripersonal Space in Primary Somatosensory Cortex
TLDR
It is argued that mirror-like responses in SI do not only reflect seen touch, but also the peripersonal space surrounding this body (in third-person-perspective) that is affected by the viewpoint of the seen hand.
Visual perception of bodily interactions in the primary somatosensory cortex
Brain imaging studies in humans have revealed the existence of a visuo‐tactile system, which matches observed touch with felt touch. In this system, the primary somatosensory cortex (SI) appears to
Seeing touch in the somatosensory cortex: A TMS study of the visual perception of touch
Recent studies suggest the existence of a visuo‐tactile mirror system, comprising the primary (SI) and secondary (SII) somatosensory cortices, which matches observed touch with felt touch. Here,

Effects of different viewing perspectives on somatosensory activations during observation of touch

Somatosensory activations during the observation of touch and a case of vision-touch synaesthesia.
TLDR
The results suggest that, in C, the mirror system for touch is overactive, above the threshold for conscious tactile perception.
A Touching Sight SII/PV Activation during the Observation and Experience of Touch
Empathy for pain and touch in the human somatosensory cortex.
TLDR
Results indicate that the S1 is not only involved in the actual perception of pain and touch but also plays an important role in extracting somatic features from social interactions.
Modulated Activation of the Human SI and SII Cortices during Observation of Hand Actions
TLDR
The results suggest that the SI and SII cortices contribute to the human mirror-neuron system, possibly providing information necessary for preserving the sense of self during action observation.
Grasping the Intentions of Others with One's Own Mirror Neuron System
TLDR
Functional magnetic resonance imaging revealed that premotor mirror neuron areas—areas active during the execution and the observation of an action—previously thought to be involved only in action recognition are actually also involved in understanding the intentions of others.
Shared Mapping of Own and Others' Bodies in Visuotactile Bimodal Area of Monkey Parietal Cortex
TLDR
It is suggested that the brain could use self representation as a reference for perception of others' body parts in parietal cortex and bimodal neurons may contribute to spatial matching between the bodies of the self and others in both action recognition and imitation.
Somatotopic organization of human secondary somatosensory cortex.
TLDR
Somatotopy in SII seems to be less fine-grained than in primary somatosensory cortex (SI), as, in contrast to SI, no separate representations of the two fingers in S II were observed.
Mirror Neurons Responding to Observation of Actions Made with Tools in Monkey Ventral Premotor Cortex
TLDR
It is proposed that tool-responding mirror neurons enable the observing monkey to extend action-understanding capacity to actions that do not strictly correspond to its motor representations, which support the notion that the motor cortex plays a crucial role in understanding action goals.
