The Neuroethics Affinity Group of the American Society for Bioethics and Humanities (ASBH) met for the third time in October 2007 to review progress in the field of neuroethics and consider high-impact priorities for the future. Closely aligned with ASBH's own goals of recruiting junior scholars to bioethics and mentoring them to successful careers, the Neuroethics Affinity Group placed a call for new ideas to be presented at the Group meeting, specifically by junior attendees. One group responded with the idea to probe a new direction for neuroethics focused on the neuroscience of gender differences. In the spirit of full disclosure, two of the authors are a student (Chalfin) and fellow (Murphy) of the program I formerly directed at Stanford University. The third (Karkazis) is junior faculty there. The intellectual ownership of the ideas in the report below, however, are entirely theirs. Like lit torches in a juggling act, there are many directions this project can go. The report is a snapshot of these authors' first iteration of the concept of women's neuroethics. Many thanks are extended to participants of the ASBH Neuroethics Affinity Group meeting whose enthusiasm and feedback was immensely helpful in shaping the concept and moving it ahead. —Judy Illes, Editor AJOB-Neuroscience

There is considerable interest in the use of neuroimaging techniques for forensic purposes. Memory detection techniques, including the well-publicized Brain Fingerprinting technique (Brain Fingerprinting Laboratories, Inc., Seattle WA), exploit the fact that the brain responds differently to sensory stimuli to which it has been exposed before. When a stimulus is specifically associated with a crime, the resulting brain activity should differentiate between someone who was present at the crime and someone who was not. This article reviews the scientific literature on three such techniques: priming, old/new, and P300 effects. The forensic potential of these techniques is evaluated based on four criteria: specificity, automaticity, encoding flexibility, and longevity. This article concludes that none of the techniques are devoid of forensic potential, although much research is yet to be done. Ethical issues, including rights to privacy and against self-incrimination, are discussed. A discussion of legal issues concludes that current memory detection techniques do not yet meet United States standards of legal admissibility.
