The non-violent men in the family were not found to have the genetic marker. Researchers suspect one gene that codes for the enzyme monoamine oxidase A (MAOA) may be malsurgery. Further research on the biological causes of violent behavio r has pointed less to a genetic link and more to brain damage that has occurred to the fetus or postnatal infant.

 The study, conducted by Raine and colleagues at USC and the University of California at Irvine, use positron emission tomography to inspect the brains of 41 murderers who had pleaded not guilty due to reasons of insanity. This was followed by a scan of 41 brains of control subjects matched for known mental disorders, as nearly as for age and gender. T he study showed that the murderers, on avera! ge, showed significantly lower place of glucose uptake in three sports stadiums of the brain -- the anterior cortex, the school principal callosum and the posterior cortex. Their evaluate were quartette, 18 and four percentage points lower, respectively, than the rates measured in control subjects playacting the same tasks.
