Re-post pour information :
Psychology Today blog network [Neurophilosophy]: The bi-monthly American magazine Psychology Today has launched a network of blogs covering a wide variety of topics, including addiction, cognitive science, sports psychology and psychotherapy.’
The network contains more than 80 blogs, many of which are written by researchers who are prominent in their respective fields. I haven’t had a look at all of them, but here are a few that caught my eye:
- Brainstorm, by the editors of the magazine;
- In Practice, by psychiatrist Peter Kramer, author of Listening to Prozac; and
- Quirky Little Things, by Jesse Bering, director of the Institute of Cognition and Culture at Queens University, Belfast.
Also, who could fail to notice, or mention, a blog called Great Sex?
Decline In Cigarette Smoking Offset By Increase In Cigars, Snuff And Other Tobacco Products: While trends in cigarette smoking and sales have declined in the US for the past decade, sales of non-cigarette tobacco products have been on the rise. Researchers found that 30 percent of the recent decline in cigarette sales may be offset by the robust sale of small cigars, snuff and roll-your-own products.
Woolly Mammoth Gene Study Changes Extinction Theory: A large genetic study of the extinct woolly mammoth has revealed that the species was not one large homogenous group, as scientists previously had assumed, and that it did not have much genetic diversity. The discovery is particularly interesting because it rules out human hunting as a contributing factor, leaving climate change and disease as the most probable causes of extinction.
What’s Mine Is Mine: Brain Scans Reveal What’s Behind The Aversion To Loss Of Possessions: Did you ever wonder why it is so difficult to part with your stuff? A new study reveals fascinating insights into the specific neuropsychological mechanisms that are linked with the potential loss of possessions. The research has important implications for both neuroscience and economics and may even explain why you are reluctant to sell your iPod.
Reverse Engineering The Brain To Model Mind-body Interactions: When you grab a cold beverage out of the cooler this summer, what is really going on between your brain, your eyes and your hands? Using magnetic resonance imaging (MRI), scientists are cataloging body parts and functions and tracing their interactions with the brain. This information is being used to create a working three-dimensional computer model of all these functions.
Sexual Arousal Dependent On Flow Of Potassium Ions In Brain Cells: When it comes to sex, a female rat knows how to avoid a communication breakdown. To announce her sexual readiness, she will automatically arch her back, deflect her tail and stand rigid to allow an aroused male to mount. Now, researchers have figured out the precise chemical and physical mechanism in a group of brain cells that controls this swayback posture, a reflex called lordosis that signals one of life’s most complex yet primitive instincts — the need for sex. The team also found that when female rats are treated with the sex hormone estradiol before the experiment, the number of cells that respond to norepinephrine soar, making the impulse to mate stronger.
Unique Drug Combination May Hold The Key To Reversing Type I Diabetes: Scientists are reporting promising results from a study that tested a novel therapy for reversing Type 1 diabetes. The treatment combines a drug that halts the immune damage that causes Type 1 diabetes with another drug that stimulates the pancreas to regenerate.
