Scientists Hunt Down Origin Of Huntington's Disease In The Brain
2014-04-29 17:24:09

Elaine Schmidt, University of California - Los Angeles Health Sciences The gene mutation that causes Huntington's disease appears in every cell in the body, yet kills only two types of brain cells. Why? UCLA scientists used a unique approach to switch the gene off in individual brain regions and zero in on those that play a role in causing the disease in mice. Published in the April 28 online edition of Nature Medicine, the research sheds light on where Huntington's starts in the...

Keep this in mind: Scientists say they've learned how your brain plucks information out of working memory when you decide to act. Say you're a busy mom trying to wrap up a work call now that you've arrived home. While you converse on your Bluetooth headset, one kid begs for an unspecified snack, another asks where his homework project has gone, and just then an urgent e-mail from your boss buzzes the phone in your purse. During the call's last few minutes these urgent requests — snack,...

"Pressing the button of the lift at your work place, or apartment building is an automatic action – a habit. You don't even really look at the different buttons; your hand is almost reaching out and pressing on its own. But what happens when you use the lift in a new place? In this case, your hand doesn't know the way, you have to locate the buttons, find the right one, and only then your hand can press a button. Here, pushing the button is a goal-directed action." It is...

Do people get caught in the cycle of overeating and drug addiction because their brain reward centers are over-active causing them to experience greater cravings for food or drugs? In a unique prospective study Oregon Research Institute (ORI) senior scientist Eric Stice, Ph.D., and colleagues tested this theory, called the reward surfeit model. The results indicated that elevated responsivity of reward regions in the brain increased the risk for future substance use, which has never been...

Chocolate Cravings Connected To Brain
2012-09-21 08:50:55

Connie K. Ho for redOrbit.com — Your Universe Online A new study has revealed that the brain might have chocolate temptations due to the production of a natural chemical that is similar to opium. The researchers looked at a group of rats to better understand the urge to overeat chocolate candies. They injected a drug that sent an artificial boost to the neostriatum, a region in the brain. With the injection, the rats ate more than double the number of M&M chocolates than they...

Concordia research helps develop first brain map of love and desire Thanks to modern science, we know that love lives in the brain, not in the heart. But where in the brain is it — and is it in the same place as sexual desire? A recent international study is the first to draw an exact map of these intimately linked feelings. "No one has ever put these two together to see the patterns of activation," says Jim Pfaus, professor of psychology at Concordia University. "We didn't know...

Using rabies virus, researcher tracks inputs to dopamine neurons A genetically-modified version of the rabies virus is helping scientists at Harvard to trace neural pathways in the brain, a research effort that could one day lead to treatments for Parkinson's disease and addiction. As described in a paper published on June 7 in the journal Neuron, a team of researchers led by Associate Professor of Molecular and Cellular Biology Naoshige Uchida used the virus to create the first-ever...

Caltech researchers find that loss aversion may be the culprit In sports, on a game show, or just on the job, what causes people to choke when the stakes are high? A new study by researchers at the California Institute of Technology (Caltech) suggests that when there are high financial incentives to succeed, people can become so afraid of losing their potentially lucrative reward that their performance suffers. It is a somewhat unexpected conclusion. After all, you would think that the...
