Neuroscience, exploring brain functions and structures, throws light on the way to better understanding of human behavior. Also neuroscience is relevant because it provides additional support for understanding immature judgment and self-control. Neurolaw, as an interdisciplinary field which links the brain to law, facilitates the pathway to better understanding of human behavior in order to regulate it accurately through incorporating neuroscience achievements in legal studies. Neurolaw is the application of neuroscience findings to legal topics such as criminal, tort, and administrative litigation and justice, agency, intent, and policy. The relevance of neuroscience to law depends intimately on the specific legal issue and context. Neuroscience intersects with the law in multiple ways, and the ethical impact of neuroscience is similarly diverse. The first broad distinction concerns the role of neuroscience in decisions about criminal responsibility. The Court has recently invoked group-based neuroscientific evidence concerning the immaturity of the adolescent brain to help reach group-wide conclusions about the extent of adolescent liability for criminal behavior. Neurolaw would help us to apply medical knowledge and technology in the legal area to achieve a more equitable legal system. The concern of neurolaw will lead us to having more concentration on both neuroscience and law to find an appropriate solution and direction between legal and neuroscientific understanding of human behavior.
