Proof That Practice Does Make Perfect

eldavojohn sends us an article about a discovery by Carnegie Mellon researchers that explains why repetitive studying or training is effective. Previous research had suggested the opposite, which ran counter to nearly everyone's personal experience. Scientists hope that this information will help us to learn more about diseases which affect the memory, such as Alzheimer's. From the article: "In a series of experiments the researchers blocked different receptors, including NMDA, to see the receptors' effect on long-term neural stimulation. They found that while the NMDA receptor is required to begin neural strengthening, a second neurotransmitter receptor -- the metabotropic glutamate (mGlu) receptor -- comes into play after this first phase of cellular learning. ...blocking mGlu receptors caused strengthening to stop."

    "The Carnegie Mellon researchers tracked the changes in the neurons by using a transgenic mouse model that Barth created. In the model, a mild sensory imbalance is created by allowing the mouse to sense its surrounding through only one whisker. Whiskers are useful in studying sensory plasticity because, like human fingers, each whisker is linked to its own unique area of the brain's cortex, making it easy to monitor activity and changes. Limiting the mouse's ability to sense its surroundings through only one whisker causes a sensory imbalance leading to increased plasticity in the cortex."

    Typical bullshit from the psychopaths who call themselves 'vivisectionists' - or - 'researchers'.

    Don't tell me - they're doing "vital research" (TM) - vital to THEIR pensions, and that's about it.

    Another huge waste of money, at the hands of idiotic cretins who can't do REAL science.
    Is the human brain the same as a mouse's brain? Is it wrong to cause suffering to others? Why are humans worth more than animals?

    How many humans were murdered last year alone, by other humans?

    The USA didn't have the resources to be so big on its own, so they basically destroyed Africa and South America, setting dictatorships that were loyal to the US, stealing their natural resources, and taking people as prisoners taking them to the other side of the world to be your SLAVES?
