Science: How to Induce Fear in “Fearless” People – Dan Nagasaki

The amygdala is the brain’s “fear center,” due to the central role it plays in regulating the body’s fear response. Increased CO2 levels…

    The global warming crowd is getting increasingly hysterical. Perhaps it’s the increasing CO2 levels…hmmm….

    Feinstein and his colleagues therefore predicted that patients with damaged amygdalas would not feel fear after inhaling the gas.

    To test this, they asked S.M., two other patients with Urbach-Wiethe disease, and 12 healthy controls to inhale 35% carbon dioxide through a mask. To their surprise, the researchers found that the brain-damaged patients did experience fear immediately after inhalation…

    Wouldn’t this result disprove their hypothesis? This is like some ‘tard bleating about global warming while there is proof that the temperature is actually falling, but claiming the temperature drop means global warming, too.

    What part of FAIL don’t today’s “scientists” understand?

    @Stranded they should at least be questioning how important the amygala is to the fear response in conditions where C02 levels are high.

    It seems like a lack of one makes a person MORE prone to a fear response when CO2 is increased. For their original hypothesis to hold the subjects with diminshed amygala should have had little reaction while the control group would have a greater fear response when CO2 levels rise.

    Somebody in the research publication process should of caught this or I’m missing something or they aren’t telling us enough about the research.

    The article’s thesis is in the first paragraph:
    People seem to have more than one way to work themselves into a panic. Contrary to a long-standing assumption of neuroscientists, humans can experience fear even when they lack the brain structure widely regarded as the brain’s ‘fear centre’.

    The only experience I have with altered gas levels is while scuba diving. I know that if I skip-breathe, the CO2 build-up produces screamingly bad headaches but Nitrogen narcosis is the real mind altering gas. In cold, dark Pacific North West waters, if I’m on air, I get a “dark narc” at about 100′ which is a definite foreboding feeling with constant checking the gas levels, paranoia and a “let’s get out of here” feelings…switch to a helium mix or ascend 10 feet and it all goes away.

    Ah, fun with the brain and gasses under high pressure…good times!

    So did this work on FDR and will it work on our present Fearless leader?
