Editing Mirror neuron (section)

==In rodents==
A number of studies have shown that rats and mice show signs of distress while witnessing another rodent receive footshocks.<ref name="pmid31600517">{{cite journal | vauthors = Keum S, Shin HS | title = Neural Basis of Observational Fear Learning: A Potential Model of Affective Empathy | journal = Neuron | volume = 104 | issue = 1 | pages = 78–86 | date = October 2019 | pmid = 31600517 | doi = 10.1016/j.neuron.2019.09.013 | s2cid = 203932127 | doi-access = free }}</ref> The group of [[Christian Keysers|Christian Keysers's]] recorded from neurons while rats experienced pain or witnessed the pain of others, and has revealed the presence of pain mirror neurons in the rat's anterior cingulate cortex, i.e. neurons that respond both while an animal experiences pain and while witnessing the pain of others.<ref name="pmid30982647">{{cite journal | vauthors = Carrillo M, Han Y, Migliorati F, Liu M, Gazzola V, Keysers C | title = Emotional Mirror Neurons in the Rat's Anterior Cingulate Cortex | journal = Current Biology | volume = 29 | issue = 8 | pages = 1301–1312.e6 | date = April 2019 | pmid = 30982647 | pmc = 6488290 | doi = 10.1016/j.cub.2019.03.024 | bibcode = 2019CBio...29E1301C }}</ref> Deactivating this region of the cingulate cortex led to reduced emotional contagion in the rats, so that observer rats showed reduced distress while witnessing another rat experience pain.<ref name="pmid30982647" /> The homologous part of the anterior cingulate cortex has been associated with empathy for pain in humans,<ref name="pmid20946964">{{cite journal | vauthors = Lamm C, Decety J, Singer T | title = Meta-analytic evidence for common and distinct neural networks associated with directly experienced pain and empathy for pain | journal = NeuroImage | volume = 54 | issue = 3 | pages = 2492–2502 | date = February 2011 | pmid = 20946964 | doi = 10.1016/j.neuroimage.2010.10.014 | s2cid = 6021487 }}</ref> suggesting a homology between the systems involved in emotional contagion in rodents and empathy/emotional contagion for pain in humans.
