\begin{abstract}
Psychopathy is characterized by glibness and superficial charm, as well
as a lack of empathy, guilt, and remorse, and is often accompanied by
antisocial behavior. The cerebral bases of this syndrome have been
mostly studied in violent subjects or those with a criminal history.
However, the antisocial component of psychopathy is not central to its
conceptualization and, in fact, psychopathic traits are present in
well-adjusted, non-criminal individuals within the general population.
Interestingly, certain psychopathy characteristics appear to be
particularly pronounced in some groups or professions. Importantly, as
these so-called adaptive or successful psychopaths do not show
antisocial tendencies or have significant psychiatric comorbidities,
they may represent an ideal population to study this trait. Here we
investigated such a group, specifically elite female judo athletes, and
compared them to matched non-athletes. Participants completed
psychopathy, anger, perspective-taking and empathic concern
questionnaires and underwent structural magnetic resonance imaging
(MRI). Grey matter density (GMD) was computed using voxel-based
morphometry from the T1-weighted images. Athletes scored significantly
higher in primary psychopathy and anger, and lower in empathy and
perspective taking. They also exhibited smaller GMD in the right
Temporal Pole, left Occipital Cortex, and left Amygdala/Hippocampus. GMD
values for the latter cluster significantly correlated with primary
psychopathy scores across both groups. These results confirm and extend
previous findings to a little-studied population and provide support for
the conceptualization of psychopathy as a dimensional personality trait
which, not only is not necessarily associated with antisocial behavior,
but may potentially have adaptive value.%
