Alzheimer’s breakthrough: A turning point in the history of the disease http://goo.gl/Z0vOQH

The discovery of the first chemical to prevent the death of brain tissue in a neurodegenerative disease has been hailed as an exciting and historic moment in medical research. (#alzheimer’s #neuroscience)

Neuroscientist says human head transplant is possible http://goo.gl/19GeR

Doctors may be able to cure current diseases such as cancer by performing human head transplants, an Italian neuroscientist has claimed. Dr Sergio Canavero, a member of the Turin Advanced Neuromodulation Group, believes not only that this procedure will be possible in the future but that it can be performed with the technology currently on offer.

Clues to what causes compulsive behavior could improve #OCD treatments http://goo.gl/5pseZ

By activating a brain circuit that controls compulsive behavior, MIT #neuroscientists have shown that they can block a compulsive behavior in mice -- a result that could help researchers develop new treatments for diseases such as obsessive-compulsive disorder (OCD) and Tourette's syndrome.

Mental stress elicits sustained increases in skin sympathetic nerve activity http://goo.gl/sQk9K

Mental #stress (MS) is a known trigger of myocardial infarction and sudden death. By activating the sympathetic #nervous system, MS may have deleterious effect on the #cardiovascular system but this process is not completely understood. The primary aim of this study was to quantify the effect of MS on skin sympathetic nerve activity (SSNA).

Blueprint for an artificial brain: Scientists experiment with memristors that imitate natural nerves http://goo.gl/nlp8u

Scientists have long been dreaming about building a computer that would work like a brain. This is because a brain is far more energy-saving than a computer, it can learn by itself, and it doesn't need any programming. Privatdozent [senior lecturer] Dr. Andy Thomas from Bielefeld University's Faculty of Physics is experimenting with memristors -- electronic microcomponents that imitate natural nerves.

Thomas and his colleagues have demonstrated that they could do this a year ago. They constructed a memristor that is capable of learning. Andy Thomas is now using his memristors as key components in a blueprint for an artificial brain.

2013 Wiley prize awarded for the discovery of the molecular mechanisms governing circadian rhythms http://bit.ly/HobgMm

Since 2002, the annual Wiley Prize in Biomedical Sciences, awarded by the Wiley Foundation, has recognized breakthrough research in pure or applied life science research. We seek to honor research that is distinguished by its excellence, originality and impact on our understanding of biological systems and processes. 

The twelfth annual #Wiley Prize in Biomedical Sciences has been awarded to Dr. Michael Young, Dr. Jeffrey Hall, and Dr. Michael Rosbash for the discovery of the molecular mechanisms governing circadian rhythms. Learn more about the Wiley Prize and this year’s winners at: http://bit.ly/HobgMm

Physicians in China treat addictions by destroying the brain’s pleasure center http://goo.gl/Kca6e [article] #neuroscience

Drug addiction in China is highly stigmatized. And now, some doctors are trying to cure it with a radical procedure known as as a "stereotactic ablation." More simply, it's the practice of destroying parts of the brain's "pleasure centers" (the nucleus accumbens) in heroin addicts and alcoholics as a way to stop drug cravings. At the same time, however, damage to this region could also impair a person's ability to experience natural longings and other emotions, including joy.

Chemotherapy disrupts learning, neurogenesis and theta activity in the adult brain http://goo.gl/VvZ9t [article] #neuroscience

Chemotherapy, especially if prolonged, disrupts attention, working memory and speed of processing in humans. Most cancer drugs that cross the blood–brain barrier also decrease adult neurogenesis...

Children exposed to music at home have enhanced development of auditory abilities http://goo.gl/lmnFX [article] #neuroscience  

The relation between informal musical activities at home and electrophysiological indices of neural auditory change detection was investigated in 2–3-year-old children. Auditory event-related potentials were recorded in a multi-feature paradigm that included frequency, duration, intensity, direction, gap deviants and attention-catching novel sounds.

Body language, not facial expressions, broadcasts what's happening to us http://goo.gl/th63J [article] #neuroscience

Expressions numbered 1,4,6 show tennis player's face on losing a point; expressions numbered 2,3,5 show a player after winning a point). Tests show that those looking at facial expressions alone cannot determine what the true emotion is.

If you think that you can judge by examining someone's facial expressions if he has just hit the jackpot in the lottery or lost everything in the stock market -- think again. Researchers at the Hebrew University of Jerusalem and at New York University and Princeton University have discovered that -- despite what leading theoretical models and conventional wisdom might indicate -- it just doesn't work that way.
