A woman born missing a finger and a thumb has grown them back – albeit as part of a phantom limb. This extraordinary occurrence shows that our brain contains a fully functional map of our body image, regardless of what our limbs actually look like. The woman, RN, was born with just three fingers on her right hand. Woman's missing digits grow back in phantom form - health - 10 August 2012
Brain might not stand in the way of free will - life - 06 August 2012 Editorial: "Can we live without free will?" Advocates of free will can rest easy, for now. A 30-year-old classic experiment that is often used to argue against free will might have been misinterpreted. In the early 1980s, Benjamin Libet at the University of California in San Francisco, used electroencephalography (EEG) to record the brain activity of volunteers who had been told to make a spontaneous movement. With the help of a precise timer that the volunteers were asked to read at the moment they became aware of the urge to act, Libet found there was a 200 millisecond delay, on average, between this urge and the movement itself.
An interoceptive predictive coding model of conscious presence | Frontiers in Consciousness Research Introduction In consciousness science, psychiatry, and virtual reality (VR), the concept of presence is used to refer to the subjective sense of reality of the world and of the self within the world (Metzinger, 2003; Sanchez-Vives and Slater, 2005). Presence is a characteristic of most normal healthy conscious experience. However, theoretical models of the neural mechanisms responsible for presence, and its disorders, are still lacking (Sanchez-Vives and Slater, 2005). Selective disturbances of conscious presence are manifest in dissociative psychiatric disorders such as depersonalization (loss of subjective sense of reality of the self) and derealization (loss of subjective sense of reality of the world).
Brain Imaging Suggests Self-Control Can be Depleted By Rick Nauert PhD Senior News Editor Reviewed by John M. Grohol, Psy.D. on June 8, 2012 A new study presents hard evidence on how the brain can run out of patience and self-control. A University of Iowa neuroscientist used functional magnetic imaging (fMRI) to confirm previous studies that show self-control is a finite commodity that is depleted by use. Researchers have learned that once the pool has dried up, we’re less likely to keep our cool the next time we’re faced with a situation that requires self-control.
Free Won't: It may be all that we have (or need) There's lots of research evidence demonstrating that many of our actions are not initiated consciously. We're not making conscious choices to act. That said, some of the strongest neuroscientific evidence indicates that our conscious choice is capable of stopping nonconsciously initiated action.
From the Free Press: A belief in free will touches nearly everything that human beings value. It is difficult to think about law, politics, religion, public policy, intimate relationships, morality—as well as feelings of remorse or personal achievement—without first imagining that every person is the true source of his or her thoughts and actions. And yet the facts tell us that free will is an illusion. In this enlightening book, Sam Harris argues that this truth about the human mind does not undermine morality or diminish the importance of social and political freedom, but it can and should change the way we think about some of the most important questions in life. In this elegant and provocative book, Sam Harris demonstrates—with great intellectual ferocity and panache—that free will is an inherently flawed and incoherent concept, even in subjective terms.
Mind controller: What is the 'burundanga' drug? This article was taken from the April 2011 issue of Wired magazine.

According to news reports from Ecuador, the last thing a motorist could recall, after waking up minus his car and possessions, was being approached by two women; in Venezuela, a girl came round in hospital to find she had been abducted and sexually assaulted; in Colombia, customers of a street vendor were robbed after eating his spiked food.
