Researchers on a study published in journal Elsevier's Cortex used physiological reactions correlated with emotional empathy in a group of traumatic brain injury patients.
Activation of facial muscles and sweat glands were measured in response to happy and angry facial expressions in adults with traumatic brain injury and a group without.
While the control group mimicked the emotional facial expressions they saw and perspired more in response to angry faces, those in the traumatic brain injury group tended to score lower in emotional empathy and were less responsive.
