BBC NEWS | Science & Environment | Simulated brain closer to thought - 1 views

  • A detailed simulation of a small region of a brain built molecule by molecule has been constructed and has recreated experimental results from real brains.
  • While many computer simulations have attempted to code in "brain-like" computation or to mimic parts of the nervous systems and brains of a variety of animals, the Blue Brain project was conceived to reverse-engineer mammal brains from real laboratory data and to build up a computer model down to the level of the molecules that make them up.
  • The first phase of the project is now complete; researchers have modeled the neocortical column - a unit of the mammalian brain known as the neocortex which is responsible for higher brain functions and thought.

  • "It starts to learn things and starts to remember things. We can actually see when it retrieves a memory, and where they retrieved it from because we can trace back every activity of every molecule, every cell, every connection and see how the memory was formed."
  • "The next phase is beginning with a 'molecularisation' process: we add in all the molecules and biochemical pathways to move toward gene expression and gene networks. We couldn't do that on our first supercomputer."
  • Organised columns of neurons have been simulated molecule by molecule
  • "This is very interesting research and I'm not criticising it, but it doesn't help us in computer science in having the intelligent behaviour of humans replicated." Professor Markram believes that by building up from one neocortical column to the entire neocortex, the ethereal "emergent properties" that characterise human thought will, step by step, make themselves apparent.

Mind - How Nonsense Sharpens the Intellect - NYTimes.com - 1 views

  •  
    "Researchers have long known that people cling to their personal biases more tightly when feeling threatened. After thinking about their own inevitable death, they become more patriotic, more religious and less tolerant of outsiders, studies find. When insulted, they profess more loyalty to friends - and when told they've done poorly on a trivia test, they even identify more strongly with their school's winning teams. #implicit learning: k. gained without awareness #rain-imaging studies of people evaluating anomalies, or working out unsettling dilemmas, show that activity in an area called the anterior cingulate cortex spikes significantly. The more activation is recorded, the greater the motivation or ability to seek and correct errors in the real world #disorientation begets creative thinking. "

Breakthrough Stanford Research: Hypnotic Trance Changes Brain Activity - 0 views

  •  
    A groundbreaking Stanford Study lead by Dr. David Spiegel has revealed what hypnotists have long known about brain activity whilst under a hypnotic trance. That is: some parts of the brain function differently under hypnosis than during normal consciousness. In essence, hypnosis indeed alters brain patterns and activity. These findings might help explain the intense absorption, lack of self-consciousness and suggestibility that characterize the hypnotic state. Would you like to discover more about Dr. David Spiegel hypnosis research findings and how you can use hypnosis to control pain and increase someone's self-esteem?

How 'negative emotionality' can make you feel sick - 0 views

  • "Negative emotionality" (NE) reflects a tendency toward depression, anxiety, and poor reaction to stress.
  • "Negative emotionality" (NE) is the antithesis of positive thinking.
  • NE refers to a propensity toward depression and anxiety, and a tendency to react to stressful situations with unpleasant emotions.

  • "Everyone has a degree of negative emotionality," said Duncan B. Clark, a psychiatrist, psychologist, director of the Pittsburgh Adolescent Alcohol Research Center, and lead author of the study. "This is not a disorder or a categorical trait; it is the degree to which an individual reports certain emotional characteristics."
  • However, I would not go so far as to say these health problems were 'all in their head.' Anxiety and depression have been shown to cause demonstrable physical changes."
