In March 2018, the National Academies of Science, Engineering and Medicine organized a workshop in order to explore the current uses of neuroscience and bring stakeholders from neuroscience and legal societies together in both the United Kingdom and the United States. Participants worked together to advance an understanding of neurotechnologies that could impact the legal system and the state of readiness to consider these technologies and where appropriate, to integrate them into the legal system. This publication summarizes the presentations and discussions from the workshop.
