In 2002, there were several meetings that drew together neuroscientists and ethicists to discuss neuroethics: the American Association for the Advancement of Science with the journal "Neuron", the University of Pennsylvania, the Royal Society, Stanford University, and the Dana Foundation. This last meeting was the largest, and resulted in a book, "Neuroethics: Mapping the Field", edited by Steven J. Marcus and published by Dana Press. That same year, the "Economist" ran a cover story entitled "Open Your Mind: The Ethics of Brain Science", "Nature" published the article "Emerging ethical issues in neuroscience". Further articles appeared on neuroethics in "Nature Neuroscience", "Neuron", and "Brain and Cognition".
