The United States Military has become increasingly interested in the possibilities of neuroscience research. Brain imaging could help to distinguish between enemy combatants from those who pose no risk, or determine the mental stability of their own soldiers. Nootropic drugs could also be used to enhance the focus and memories of soldiers, allowing for better recognition of dangers and improved performance. However, this has led to questions regarding the personal privacy of soldiers and detainees, and the compliance requirements that may come with performance enhancement. Although the civilian court system is reluctant to use unproven technologies, the military's future use of them may generate controversy over the possible innocence or guilt of enemy combatants.
