Seeing disfigured faces prompts negative brain and behavior responses

Neuroscience NewsMay 29, 2019

Neuroimaging reveals people experience a diminished neural response in the anterior cingulate cortex when shown images of others with facial disfigurements. A similar response is also seen when people view other stigmatized people, such as those who are homeless. The diminished activity may explain why people are less empathetic toward those who have facial disfigurements and may help explain the underlying neural mechanism for dehumanization. ...
