Me, Myself and My Stranger: Understanding the Neuroscience of Selfhood

Me, Myself and My Stranger: Understanding the Neuroscience of Selfhood
Where are you right now? Maybe you are at home, the office or a coffee shop—but such responses provide only a partial answer to the question at hand. Asked another way, what is the location of your "self" as you read this sentence? Like most people, you probably have a strong sense that your conscious self is housed within your physical body, regardless of your surroundings. But sometimes this spatial self-location goes awry. During a so-called out-of-body experience, for example, one's self seems to be transported outside the physical body into a surreal perspective—some people even believe they are viewing their bodies from above, as though their true selves were floating. A new paper offers examples of rare bodily illusions that are not confined to a single limb, nor are they complete out-of-body experiences—they are somewhere in between. Patient 1 was a 55-year-old man who had suffered from epilepsy since he was 14 years old.

Neuroscience of free will Neuroscience of free will is the part of neurophilosophy that studies the interconnections between free will and neuroscience. As it has become possible to study the living brain, researchers have begun to watch decision making processes at work. Findings could carry implications for our sense of agency and for moral responsibility and the role of consciousness in general.[1][2][3] Relevant findings include the pioneering study by Benjamin Libet and its subsequent redesigns; these studies were able to detect activity related to a decision to move, and the activity appears to begin briefly before people become conscious of it.[4] Other studies try to predict activity before overt action occurs.[5] Taken together, these various findings show that at least some actions - like moving a finger - are initiated unconsciously at first, and enter consciousness afterward.[6]

Wellcome Image of the Month: Celebration of the brain Recently, the Wellcome Trust supported a play called 2401 Objects. It tells the story of Henry Molaison, who suffered from epilepsy and underwent experimental surgery in an attempt to cure his frequent and often disruptive seizures. Unbeknown to Henry at the time, the operation was set to become one of the most influential case studies in the history of neuroscience research. Patient HM, as Henry later became known within the research community, provided a rare but hugely powerful insight into the cognitive and neural organisation of memory, both experimentally and theoretically.

12 Tips for Getting Regular Exercise and the Benefits for Happiness and Fitness Exercise is a KEY to happiness . Research shows that people who exercise are healthier, more energetic, think more clearly, sleep better, and have delayed onset of dementia . They get relief from anxiety and mild depression . They perform better at work . Also, although it’s tempting to flop down on the couch when you’re feeling exhausted, exercise is actually a great way to boost energy levels . Feeling tired is a reason to exercise, not a reason to skip exercise. Antarctic Ice Sheet Preserves Invisible Mountain Range Buried deep beneath East Antarctica’s ice sheet, the Gamburtsev Mountains are the world’s most invisible range. New research suggests that overlying ice like that hiding them from view today could have preserved their rugged topography for the past 300 million years. The work bolsters the counterintuitive notion that glaciers, rather than just carving down young peaks into eroded hills like a buzzsaw, could sometimes protect high jagged terrain. “It’s feasible for topography to be preserved,” says Stephen Cox, a graduate student at Caltech and coauthor of a paper scheduled to appear in Geophysical Research Letters.

New resources, information, books and links added. Only 7% of communication is verbal communication. (see note) 38% of it depends on our intonation, or the sound of our voice. Technology Review: Brain Coprocessors Ed Boyden, an Assistant Professor, Biological Engineering, and Brain and Cognitive Sciences at the MIT Media Lab, will give a presentation on using light to study and treat brain disorders at 3.30pm on Wednesday at EmTech 2010. Watch a live feed of the session here. The last few decades have seen a surge of invention of technologies that enable the observation or perturbation of information in the brain. Functional MRI, which measures blood flow changes associated with brain activity, is being explored for purposes as diverse as lie detection, prediction of human decision making, and assessment of language recovery after stroke. Implanted electrical stimulators, which enable control of neural circuit activity, are borne by hundreds of thousands of people to treat conditions such as deafness, Parkinson’s disease, and obsessive-compulsive disorder.

The neuroscientific study of hallucinogens Recently, an important and landmark paper was published in PLoS ONE (hooray open access!) titled, "Investigating the Mechanisms of Hallucinogen-Induced Visions Using 3,4-Methylenedioxyamphetamine (MDA): A Randomized Controlled Trial in Humans". It sounds daunting, but trust me, it's a very cool, approachable study. Now, in the spirit of full-disclosure, the lead author Dr. Matthew Baggott (hereafter referred to as "Matt"), is a friend of mine from grad school and he's been kind enough to grant me a very thorough interview for this post. The interview is quite long, so I'll give a brief overview of the research and some of Matt's comments, but I've posted the entire interview at the bottom of this post.

Madonna–whore complex In sexual politics the view of women as either Madonnas or whores limits women's sexual expression, offering two mutually exclusive ways to construct a sexual identity.[4] The term is also used popularly, often with subtly different meanings.

How to Detect Lies - body language, reactions, speech patterns Interesting Info -> Lying Index -> How to Detect Lies Become a Human Lie Detector (Part 1) Warning: sometimes ignorance is bliss. After gaining this knowledge, you may be hurt when it is obvious that someone is lying to you. The following deception detection techniques are used by police, forensic psychologists, security experts and other investigators. Introduction to Detecting Lies:

Scientists extract images directly from brain Researchers from Japan's ATR Computational Neuroscience Laboratories have developed new brain analysis technology that can reconstruct the images inside a person's mind and display them on a computer monitor, it was announced on December 11. According to the researchers, further development of the technology may soon make it possible to view other people's dreams while they sleep. The scientists were able to reconstruct various images viewed by a person by analyzing changes in their cerebral blood flow. Using a functional magnetic resonance imaging (fMRI) machine, the researchers first mapped the blood flow changes that occurred in the cerebral visual cortex as subjects viewed various images held in front of their eyes.
