Optogenetics Therapy Binge Drinking
2014-01-06 15:09:17

Brett Smith for redOrbit.com - Your Universe Online A team of American researchers has stumbled upon a way to prevent binge drinking in animal subjects, according to a new report in the journal Frontiers in Neuroscience. By using light to stimulate specific neurons in the brain, the study team was able to show a cause-and-effect relationship between the discharge of dopamine in the brain and drinking behaviors of animals. “For decades, we have observed that particular brain regions...

Neuroscience Method Of Optogenetics As Good As Electrical Stimulation
2013-12-12 17:27:06

Brown University Neuroscientists are eagerly, but not always successfully, looking for proof that optogenetics – a celebrated technique that uses pulses of visible light to genetically alter brain cells to be excited or silenced – can be as successful in complex and large brains as it has been in rodent models. A new study in the journal Current Biology may be the most definitive demonstration yet that the technique can work in nonhuman primates as well as, or even a little better...

A new technique allows researchers to activate proteins in the brain by shining an LED light on them With the flick of a light switch, researchers at the Salk Institute for Biological Studies can change the shape of a protein in the brain of a mouse, turning on the protein at the precise moment they want. This allows the scientists to observe the exact effect of the protein's activation. The new method, described in the October 16 issue of the journal Neuron, relies on specially engineered...

New Field Of Optogenetics Could Offer Solutions For Cardiac Arrhythmia
2013-09-19 14:05:49

National Science Foundation With a few flicks of a light switch--on-off-on-off--Stanford University's Oscar Abilez is one step closer to changing the lives of millions. Why? Because as a focused speck of light turns on and off in Abilez's lab, a cluster of heart cells begins to expand and contract. He demonstrates that he can control the rhythm of a heart using just light. Currently, 4 million Americans suffer from some degree of cardiac arrhythmia, wherein a person's heart beats too...

"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...

Using a miniature electronic device implanted in the brain, scientists have tapped into the internal reward system of mice, prodding neurons to release dopamine, a chemical associated with pleasure. The researchers, at Washington University School of Medicine in St. Louis and the University of Illinois at Urbana-Champaign, developed tiny devices, containing light emitting diodes (LEDs) the size of individual neurons. The devices activate brain cells with light. The scientists report their...
