The collaborative study of the mind involving neuroscience, psychology, and philosophy has been and continues to be an extremely active and productive area of research, appealing to those who wish both to apply empirical brain research to enduring questions of human nature and apply logical and conceptual analysis to neuroscience and its potential policy, medical, and legal applications. Broad areas of study in this field include the nature of the mind, the nature of brain activity, the mind-brain relationship, artificial intelligence, neuroethics, neurolaw, and models of psychopathology.
