Forensic Science, Statistics & the Law: True Lies: fMRI Evidence in United States v. Semrau. This month, the U.S. Court of Appeals for the Sixth Circuit issued an opinion on “a matter of first impression in any jurisdiction.” The case is United States v. Semrau, No. 11-5396, 2012 WL 3871357 (6th Cir. Sept. 7, 2012). Its subject is the admissibility of the latest twist, the ne plus ultra, in lie detection—functional magnetic resonance imaging (fMRI).
In several ways, the case resembles what may well be the single most cited case on scientific evidence—namely, Frye v. In United States v. Dr. Despite these parallels, Laken is not Marston, and Semrau is not Frye. Furthermore, in Frye, there was no previous body of law imposing a demanding standard on the proponents of scientific evidence—the Frye court created from whole cloth the influential “general acceptance” test.3/ In Semrau, the court began with the Federal Rules of Evidence, ornately embroidered with the Supreme Court's opinions in Daubert v. The reasoning is peculiar, or at least incomplete. So far so good. Dr. Dr. Dr. 1. How does fMRI brain scanning work? Alan Alda and Dr. Nancy Kanwisher, MIT. Neuroethics and fMRI: Mapping a Fledgling Relationship. Human functional magnetic resonance imaging (fMRI) informs the understanding of the neural basis of mental function and is a key domain of ethical enquiry.
It raises questions about the practice and implications of research, and reflexively informs ethics through the empirical investigation of moral judgments. It is at the centre of debate surrounding the importance of neuroscience findings for concepts such as personhood and free will, and the extent of their practical consequences. Here, we map the landscape of fMRI and neuroethics, using citation analysis to uncover salient topics. We find that this landscape is sparsely populated: despite previous calls for debate, there are few articles that discuss both fMRI and ethical, legal, or social implications (ELSI), and even fewer direct citations between the two literatures.

Chapter 7: Neuroscience-Based Lie Detection: The Need for Regulation - American Academy of Arts & Sciences. “I swear I didn’t do it.” “The check is in the mail.” “The article is almost done.” In our lives and in our legal system we often are vitally interested in whether someone is telling us the truth. Over the years, humans have used reputation, body language, oaths, and even torture as lie detectors.
In the twentieth century, polygraphs and truth serum made bids for widespread use. The possibility of effective lie detection raises a host of legal and ethical questions. These issues are fascinating and the temptation is strong to pursue them, but we must not forget a crucial first question: does neuroscience-based lie detection work and, if so, how well? It is not. Arguably all lie detection, like all human cognitive behavior, has its roots in neuroscience, but the term neuroscience-based lie detection describes newer methods of lie detection that try to detect deception based on information about activity in a subject’s brain.
First, almost none of the work has been replicated. The U.S. The Brain on Trial - David Eagleman. Advances in brain science are calling into question the volition behind many criminal acts. A leading neuroscientist describes how the foundations of our criminal-justice system are beginning to crumble, and proposes a new way forward for law and order. On the steamy first day of August 1966, Charles Whitman took an elevator to the top floor of the University of Texas Tower in Austin. The 25-year-old climbed the stairs to the observation deck, lugging with him a footlocker full of guns and ammunition. At the top, he killed a receptionist with the butt of his rifle. Two families of tourists came up the stairwell; he shot at them at point-blank range. Then he began to fire indiscriminately from the deck at people below. The evening before, Whitman had sat at his typewriter and composed a suicide note: I don’t really understand myself these days.
By the time the police shot him dead, Whitman had killed 13 people and wounded 32 more. For that matter, so did Whitman. Commentary: The Future of Forensic Functional Brain Imaging. What is Functional Magnetic Resonance Imaging (fMRI)? Functional magnetic resonance imaging, or fMRI, is a technique for measuring brain activity. It works by detecting the changes in blood oxygenation and flow that occur in response to neural activity – when a brain area is more active it consumes more oxygen and to meet this increased demand blood flow increases to the active area. fMRI can be used to produce activation maps showing which parts of the brain are involved in a particular mental process.
The development of FMRI in the 1990s, generally credited to Seiji Ogawa and Ken Kwong, is the latest in long line of innovations, including positron emission tomography (PET) and near infrared spectroscopy (NIRS), which use blood flow and oxygen metabolism to infer brain activity. As a brain imaging technique FMRI has several significant advantages: 1. It is non-invasive and doesn’t involve radiation, making it safe for the subject. 2. It has excellent spatial and good temporal resolution. 3. How Does an fMRI Work?
