Emory Health Sciences Differences in basal ganglia, similarity to inflammation-induced fatigue A brain imaging study shows that patients with chronic fatigue syndrome may have reduced responses, compared with healthy controls, in a region of the brain connected with fatigue. The findings suggest that chronic fatigue syndrome is associated with changes in the brain involving brain circuits that regulate motor activity and motivation. Compared with healthy controls, patients with...

And how do separate small elements come together to become a unique and meaningful sequence? When you learn how to play the piano, first you have to learn notes, scales and chords and only then will you be able to play a piece of music. The same principle applies to speech and to reading, where instead of scales you have to learn the alphabet and the rules of grammar. But how do separate small elements come together to become a unique and meaningful sequence? It has been shown that a...

'Odor is a means of chemical communication between mother and child' -- Johannes Frasnelli, University of Montreal What woman has not wanted to gobble up a baby placed in her arms, even if the baby is not hers? This reaction, which everyone has noticed or felt, could have biological underpinnings related to maternal functions. For the first time, an international team of researchers has found evidence of this phenomenon in the neural networks associated with reward. "The olfactory -- thus...

"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...

Salk-Gladstone Study Helps Scientists Decode Circuitry That Guides Brain Function
2013-06-28 09:51:01

Salk Institute The power of the brain lies in its trillions of intercellular connections, called synapses that together form complex neural "networks." While neuroscientists have long sought to map these individual connections to see how they influence specific brain functions, traditional techniques have been unsuccessful. Now, scientists at the Salk Institute and the Gladstone Institutes, using an innovative brain- tracing technique, have found a way to untangle these networks. These...

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...

A new study by scientists at King's College London and the University of Arizona (UA) published in Science reveals the deep similarities in how the brain regulates behaviour in arthropods (such as flies and crabs) and vertebrates (such as fish, mice and humans). The findings shed new light on the evolution of the brain and behaviour and may aid understanding of disease mechanisms underlying mental health problems. Based on their own findings and available literature, Dr Frank Hirth...

New MRI technique could help doctors track how patients respond to treatment A new imaging technique developed at MIT offers the first glimpse of the degeneration of two brain structures affected by Parkinson's disease. The technique, which combines several types of magnetic resonance imaging (MRI), could allow doctors to better monitor patients' progression and track the effectiveness of potential new treatments, says Suzanne Corkin, MIT professor emerita of neuroscience and leader of...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
