ScienceDaily (Feb. 9, 2009) — Researchers at the Swedish medical university Karolinska Institutet have shown for the first time that the active training of the working memory brings about visible changes in the number of dopamine receptors in the human brain. The study, which is published in the journal Science, was conducted with the help of PET scanning and provides deeper insight into the complex interplay between cognition and the brain’s biological structure.
CHICAGO, Dec 03, 2008 /PRNewswire-USNewswire via COMTEX/ — Researchers using functional MRI (fMRI) have determined that the circuitry in the area of the brain responsible for suppressing memory is dysfunctional in patients suffering from stress-related psychiatric disorders. Results of the study will be presented today at the annual meeting of the Radiological Society of North America (RSNA).
In the last few years, working from home has gone from being a rarity to a reality.
With advances in technology, more people are able to link to work from their home computers or laptops. And as employees continue to crave flexibility and yearn for a better work/life balance, more people are working from home for at least part of their workweek.
Adults with primary insomnia have a specific neurochemical imbalance that makes it more difficult for their brains to settle down for sleep, a new study says.
People with primary insomnia for more than six months have 30 percent less gamma-aminobutyric acid (GABA), a chemical that slows overall activity in many brain areas, according to the report in the Nov. 1 issue ofSleep. A “racing mind” and an inability to shut down at night is a common complaint of people with primary insomnia.
Can scientists predict who will develop anxiety disorders years in advance? UCLA psychology professor Michelle Craske thinks so. She is four years into an eight-year study evaluating 650 students, who were 16 when the study began, to identify risk factors for the development of anxiety and depression — the most comprehensive study of its kind.
According to the National Institute of Mental Health (NIMH), about six million American men suffer from depression every year. Yet psychologists know that men are far less likely than women to seek help not only for all mental-health problems, but depression in particular.
According to the NIMH public-information campaign, “Real Men. Real Depression.,” which began in 2003, men may be unlikely to admit to depressive symptoms and seek help.
Finnish scientists have identified genes that may predispose to anxiety disorders. Research conducted under the supervision of Academy Research Fellow Iiris Hovatta have focused on genes that influence human behaviour, and some of the studied genes show a statistical association with specific anxiety disorders.
There are plenty of people who coast across the Chesapeake Bay Bridge without even a flicker of anxiety, never giving a thought to any greater calamity than whether they forgot the sunscreen or made an error in judgment in packing the Speedo.
But for some people, the 4.3-mile span sparks feelings from mild consternation to outright panic. What if the bridge sways or collapses? What if an erratic driver forces them out of their lane and into the drink? Or worse still, what if they completely freak out and in a state of panic accidentally drive themselves into the bay?

The longer Philadelphia Eagles guard Shawn Andrews was missing from training camp, the more suspicious some fans grew as to the reasons why.
He’s probably on drugs, some diehards speculated in the blogosphere. He’s holding out for more money, others wrote on the Philadelphia newspapers Web pages. He’s fat, lazy and just doesn’t want to get hurt in football contact drills, still others opined.
Smiling, dancing and spending less money are just some of the ways to feel happier according to a government scientific adviser.
