Anxiety Culture: How to Stop Worrying
Undoing the Worrying Habit Once acquired, the habit of worrying seems hard to stop. We're raised to worry and aren't considered "grown up" until we perfect the art. Teenagers are told: "you'd better start worrying about your future" . If your worries aren't at least as frequent as your bowel movements, you're seen as irresponsible, childish, aimless.

A recent literature review of commentaries and ‘state of the art’ articles from researchers in psychiatric genetics (PMG) offers a consensus about progress in the science of genetics, disappointments in the discovery of new and effective treatments, and a general optimism about the future of the field.
How the Brain Stops Time
One of the strangest side-effects of intense fear is time dilation, the apparent slowing-down of time. It's a common trope in movies and TV shows, like the memorable scene from The Matrix in which time slows down so dramatically that bullets fired at the hero seem to move at a walking pace. In real life, our perceptions aren't keyed up quite that dramatically, but survivors of life-and-death situations often report that things seem to take longer to happen, objects fall more slowly, and they're capable of complex thoughts in what would normally be the blink of an eye. Now a research team from Israel reports that not only does time slow down, but that it slows down more for some than for others.Me, Myself and My Stranger: Understanding the Neuroscience of Selfhood
SELF REFLECTION: Bodily illusions teach neuroscientists about the sense of self. Image: crimfants, flickr.com 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.
The Dark Side of Oxytocin, the Hormone of Love - Ethnocentrism
Yes, you knew there had to be a catch. As oxytocin comes into sharper focus, its social radius of action turns out to have definite limits. The love and trust it promotes are not toward the world in general, just toward a person’s in-group. Oxytocin turns out to be the hormone of the clan, not of universal brotherhood.Neuroscientists reveal magicians' secrets - Technology & science - Science - LiveScience

Scientists extract images directly from brain ::: Pink Tentacle
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. Subjects were shown 400 random 10 x 10 pixel black-and-white images for a period of 12 seconds each.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.
