Neuroscience-based methods of lie detection already may have passed the test of public acceptance, but whether they work is still an open question in the scientific community. The growing disparity between public and scientific understanding of “forensic neuroscience” was one of several pressing issues that brought nearly 200 people to Washington, D.C., for the annual meeting of the Neuroethics Society.

With neuroscience on the threshold of major advances in the pharmacological management of addiction, Richard J. Bonnie, Donna T. Chen and Charles P. O’Brien consider the ethical and legal implications of different methods for administering one successful drug, injectable naltrexone, to convicted drug offenders.

Neurologists exploring deep brain stimulation (DBS) treatment face serious ethical challenges because the invasive technique is still in very early testing yet many in the public think it's ready for prime time, experts said during a public forum at the Dana Center in Washington, DC. Panelists included Philip Campbell, Ph.D., Nature and Nature Publications; Jonathan Moreno, Ph.D., University of Pennsylvania; Helen Mayberg, M.D., Emory University; and Joseph Fins, M.D., Weill Cornell Medical College; the even was moderated by Judy Illes, Ph.D., Canada Research Chair in Neuroethics.
Interview
Q&A with Martha Farah
by Aalok Mehta
Some companies are rushing to cash in on promising but unproved neuroscience developments, including offering truth detection, reading tutors and brain exercisers. Martha Farah, director for the Center for Cognitive Neuroscience at the University of Pennsylvania, describes how that might not be good news for consumers. Part of a series featuring speakers at the Neuroethics Society annual meeting, Thursday and Friday in Washington, D.C.

The independent study Web course "Advances in Neuroscience and their Ethical Implications" includes sections on neuroimaging, neurogenetics, neuropharmacology and neurotechnology, with background information, case studies and a resource list with links.
Donald Pfaff, Ph.D., head of the Laboratory of Neurobiology and Behavior at Rockefeller University, gives us a science-based hypothesis of why humans across time and geography have such similar notions of right and wrong.

Neuromarketers claim that by using high-tech imaging to study the brain’s reactions directly, they can get information that's more detailed and reliable than traditional surveys and focus groups—and so sell more to more consumers. The Nielsen Company, which provides the famous “Nielsen ratings,” has just bought in. Should the rest of us?

Brain researchers must be cognizant not just of the neuroethical implications of their work, but also of the ethical issues in their own professional behavior.
More evidence suggests that brain dysfunction can compromise free will
by Tom Valeo
Researchers at University College London have detected an impulse control area of the frontal lobes by using functional magnetic resonance imaging (fMRI). Their work adds to the debate over how much "free will" is a matter of brain matter and how much is a matter of self-control.
