Callous and unemotional traits are linked to differences in brain structure in boys, but not in girls, according to a research by a European team led by the University of Basel and University of Basel Psychiatric Hospital.
In a study, published in the journal Neuroimage: Clinical, the researchers have studied on brain development in 189 adolescents.
The researchers, using magnetic resonance imaging, were able to take a closer look at the brain development of typically-developing 189 teenagers to find out whether callous-unemotional traits are linked to differences in brain structure.
The researchers found that the relationship between callous-unemotional traits and brain structure differs between boys and girls.
Callous-unemotional traits are characterised by a lack of empathy, a disregard for others’ feelings and shallow or deficient affect, such as a lack of remorse or guilt. These traits have been linked to deficits in development of the conscience and of empathy.
The findings showed that in typically-developing boys, the volume of the anterior insula or gray matter volume — a brain region implicated in recognising emotions in others and empathy — is larger in those with higher levels of callous-unemotional traits.
The volume explained 19% of the variance in callous-unemotional traits seen only in, but not in girls with the same personality traits.

“Our findings demonstrate that callous-unemotional traits are related to differences in brain structure in typically-developing boys without a clinical diagnosis,” said lead author Nora Maria Raschle from the University of Basel in Switzerland.
