For 176 participants, the grey matter density had been estimated on the score test board and it was rated according to the cognitive empathy level rather than affective or emotional empathy. The study involved looking if people having more brain cells in any particular region of the brain are better than all the other types of empathy. The researchers found that the physical difference in the brain of people who connect to other people emotionally compared to the people who responded in a rational way. This research work was lead by Robert Eres and he pointed that the people who have high effective empathy were the ones who fear while watching a scary movie and start crying on seeing any emotional scene. They are considered to be more rational person.
The researches implemented a neuroimaging analysis technique to investigate the focal differences in the anatomy of brain. The people who achieved high scores had greater empathy for grey matter that is found in the insula, i.e. the middle of the brain. Their brain had high density and it could connect the two parts of the brain. Both the affective and the cognitive empathy has been represented in the morphometry of the brain. It shows an evidence for both neutral and structural correlation. This research has aroused many questions in the mind of the people. They would like to know if they could train themselves to be more empathic or not.
