Data from animal studies have identified oxytocin as an important modulator of social aggression. We have previously reported on a relationship between cerebrospinal fluid (CSF) levels of vasopressin and life history of aggressive behavior, a finding that is consistent with animal data. We hypothesized that CSF Oxytocin levels would be inversely related to dimensional measures of lifetime aggression.
