Introverts Who Pretend To Be Extroverts Report Being HappierNews
If you are an introvert, force yourself to be an extravert. You’ll be happier. That’s the suggestion of the first-ever study asking people to act like extraverts for a prolonged period. For one week, the 123 participants were asked to – in some cases – push the boundaries of their willingness to engage, by acting as extraverts.READ MORE
The Marketplace in Our BrainNews
A new study has found that bidding in a competitive market, our brains use a special type of heuristic to adjust the price depending on the success of previous attempts to buy goods. Moreover, this learning mechanism involves not only the cerebral cortex, but the evolutionary ancient brain area of the striatum.
A New Piece of the Alzheimer's PuzzleNews
Two years after discovering a way to neutralize a rogue protein linked to Alzheimer's disease, University of Alberta Distinguished University Professor and neurologist Jack Jhamandas has found a new piece of the Alzheimer's puzzle, bringing him closer to a treatment for the disease.
Zebrafish Study Shows Brain Activity Intensity Drives the Need for SleepNews
The intensity of brain activity during the day, notwithstanding how long we've been awake, appears to increase our need for sleep, according to a new UCL study in zebrafish.
First brain imaging studies of African infants raise hope of insight into cognitive effects of nutritionNews Apr 24, 2014
Brain activity of babies in developing countries could be monitored from birth to reveal the first signs of cognitive dysfunction, using a new technique piloted by a London-based university collaboration.READ MORE
A novel compound that targets an important brain receptor has a dramatic effect against a host of cocaine addiction behaviors, including relapse behavior, a University at Buffalo animal study has found.READ MORE
Protein clusters targeted by medications for neurodegenerative diseases actually serve to protect brain cellsNews Apr 24, 2014
People diagnosed with Huntington's disease, most in their mid-thirties and forties, face a devastating prognosis: complete mental, physical, and behavioral decline within two decades. "Mutant" protein clusters, long blamed for the progression of the genetic disease, have been the primary focus of therapies in development by pharmaceutical companies.READ MORE
A human biomarker, if found, could have implications in determining brain tumor radiotherapy treatment. Johns Hopkins scientists report that rats exposed to high-energy particles, simulating conditions astronauts would face on a long-term deep space mission, show lapses in attention and slower reaction times, even when the radiation exposure is in extremely low dose ranges.READ MORE
The first study to look at how physical activity may impact the loss of hippocampal volume in people at genetic risk for Alzheimer's disease A study of older adults at increased risk for Alzheimer's disease shows that moderate physical activity may protect brain health and stave off shrinkage of the hippocampus – the brain region responsible for memory and spatial orientation that is attacked first in Alzheimer's disease.READ MORE
Scientists from the Florida campus of The Scripps Research Institute (TSRI) have identified a protein complex that plays a critical but previously unknown role in learning and memory formation.READ MORE
Using an ambulance that included a computed tomography (CT) scanner, point-of-care laboratory, telemedicine connection and a specialized prehospital stroke team resulted in decreased time to treatment for ischemic stroke, according to a study in the April 23/30 issue of JAMA, a neurology theme issue.READ MORE
Although some studies have suggested that the drug lorazepam may be more effective or safer than the drug diazepam in treating a type of epileptic seizures among children, a randomized trial finds that lorazepam is not better at stopping seizures compared to diazepam, according to a recent study in JAMA, a neurology theme issue.READ MORE
