Abstract
Our study shows the case of a psychopath prisoner who has been in jail for three years accused of rape. The subject was evaluated through the Psychopathy Checklist-Revised (PCL-R) and Quantitative Electroencephalogram (QEEG). QEEG measures used in this study were absolute power and occipital Alpha medium frequency. Values were transformed into Z score and compared with the QEEG normative database. Results showed a Theta excess and Alpha decrease; moreover occipital Alpha medium frequency was below the norm for the subject's age. Findings suggest a cortical hypoactivation; some theories suggest that some psychopath's features can be explained by this low activation.
