{{main|Somatosensory system#Neural processing of social touch}}The ''somatosensory cortex'' is a part of the brain that receives and encodes sensory information from receptors of the entire body.<ref>{{Cite web|url=https://human-memory.net/somatosensory-cortex/|title=Somatosensory Cortex|date=31 October 2019|website=The Human Memory|access-date=8 March 2020}}</ref>

[[Affective|Affective touch]] is a type of sensory information that elicits an emotional reaction and is usually social in nature. Such information is actually coded differently than other sensory information. Though the intensity of affective touch is still encoded in the primary somatosensory cortex, the feeling of pleasantness associated with affective touch is activated more in the [[anterior cingulate cortex]]. Increased [[Blood-oxygen-level-dependent imaging|blood oxygen level-dependent]] (BOLD) contrast imaging, identified during [[functional magnetic resonance imaging]] (fMRI), shows that signals in the anterior cingulate cortex, as well as the [[prefrontal cortex]], are highly correlated with pleasantness scores of affective touch. Inhibitory [[transcranial magnetic stimulation]] (TMS) of the primary somatosensory cortex inhibits the perception of affective touch intensity, but not affective touch pleasantness. Therefore, the S1 is not directly involved in processing socially affective touch pleasantness, but still plays a role in discriminating touch location and intensity.<ref>{{cite journal|last1=Case|first1=LK|last2=Laubacher|first2=CM|last3=Olausson|first3=H|last4=Wang|first4=B|last5=Spagnolo|first5=PA|last6=Bushnell|first6=MC|title=Encoding of Touch Intensity But Not Pleasantness in Human Primary Somatosensory Cortex|journal=J Neurosci|volume=36|issue=21|pages=5850–60|doi=10.1523/JNEUROSCI.1130-15.2016|pmc=4879201|pmid=27225773|year=2016}}</ref>
