Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition ( DSM-IV ) defines the essential characteristics as "a persistent pattern of behavior in which the basic rights of others or major age-appropriate social norms are violated.“ Behaviors used to classify CD fall into the 4 main categories of (1) aggression toward people and animals; (2) destruction of property without aggression toward people or animals; (3) deceitfulness, lying, and theft; and (4) serious violations of rules.
Oppositional defiant disorder (ODD) is discriminated from CD based on the defiance of rules and argumentative verbal interactions involved in ODD CD involves more deliberate aggression, destruction, deceit, and serious rule violations, such as staying out all night or chronic school truancy. These children are more likely to develop adult antisocial personality disorder than individuals with the adolescent-onset type.

Traits not correlated with either factor Promiscuous sexual behavior Many short-term marital relationships Criminal versatility Acquired behavioural sociopathy/sociological conditioning (Item 21: a newly identified trait i.e. a person relying on sociological strategies and tricks to deceive)
Millon s Test The test is modeled on four scales 14 Personality Disorder Scales 10 Clinical Syndrome Scales 5 Correction Scales: 3 Modifying Indices (which determine the patient's response style and can detect random responding); 2 Random Response Indicatiors 42 Grossman Personality Facet Scales (based on Seth Grossman 's theories of personality and psychopathology) [

Neuroscience is the scientific study of the nervous system .  Traditionally, neuroscience has been seen as a branch of biology . However, it is currently an interdisciplinary science that collaborates with other fields such as chemistry , computer science , engineering , linguistics , mathematics , medicine and allied disciplines , philosophy , physics , and psychology . The term neurobiology is usually used interchangeably with the term neuroscience, although the former refers specifically to the biology of the nervous system , whereas the latter refers to the entire science of the nervous system
The scope of neuroscience has broadened to include different approaches used to study the molecular , cellular , developmental , structural , functional , evolutionary , computational , and medical aspects of the nervous system. The techniques used by neuroscientists have also expanded enormously, from molecular and cellular studies of individual nerve cells to imaging of sensory and motor tasks in the brain . Recent theoretical advances in neuroscience have also been aided by the study of neural networks .
The P3 Wave. Images of the crime cannot be concealed within cortices of the brain— there is no place to hide . Evidence stored in the brain will match evidence extracted at the crime scene. The pattern allows for a positive reading detected by waves occurring 300 milliseconds after a stimulus—The P3 Wave). ERP Event-related-potential is the index for how the brain process meaningful events with the distinctive P3 paradigm as events known only to a perpetrator and outside his/her control.
