How vision captures sound now somewhat uncertain Contrary to previous research, researchers have found that neurons in a particular brain region respond differently, not similarly, based on whether the stimuli is visual or auditory. The finding provides insight into how vision captures the location of perceived sound.
Drugs that weaken traumatic memories hold promise for PTSD treatment Memories of traumatic events often last a lifetime because they are so difficult to treat through behavioral approaches. A preclinical study reveals that drugs known as histone deacetylase inhibitors can enhance the brain's ability to permanently replace old traumatic memories with new memories, opening promising avenues for the treatment of post-traumatic stress disorder and other anxiety disorders.
Scientists discover two proteins that control chandelier cell architecture Chandelier cells are neurons that use their unique shape to act like master circuit breakers in the brain. These cells have branching projections that allow one chandelier cell to block the output of hundreds of other neurons. Defects in their function have been linked to epilepsy and schizophrenia. In work published, scientists identify two proteins that control the structure of chandelier cells, offering insight into how the cells are regulated.
The way to a chimpanzee's heart is through its stomach Researchers measured the urinary oxytocin levels in wild chimpanzees after food sharing and found them to be elevated in both donor and receiver compared to social feeding events without sharing. Furthermore, oxytocin levels were higher after food sharing than after grooming, another cooperative behavior, suggesting that food sharing might play a more important role in promoting social bonding.
Assessing others: Evaluating expertise of humans, computer algorithms Researchers used fMRI technology to monitor the brain activity of volunteers as they interacted with "experts" -- some human, others computer algorithms -- to predict the behavior of a hypothetical financial asset. Volunteers responded more positively to human rather than computer "experts."
Brain on autopilot: How the architecture of the brain shapes its functioning The structure of the human brain is complex, reminiscent of a circuit diagram with countless connections. But what role does this architecture play in the functioning of the brain?

Image perception in the blink of an eye Neuroscientists find that the brain can identify images seen for as little as 13 milliseconds.
Mental health of Spanish men worsened with economic crisis Experts and social organizations have warned of the negative effects that the economic crisis could mean for the health of the population. But it was not easy to demonstrate with data what is happening. A new, comparative analysis of the last two National Health Surveys revealed a rise in mental health problems in men, which contrasts on the other hand with a decrease in women.   
Discovery of quantum vibrations in 'microtubules' inside brain neurons supports controversial theory of consciousness A review and update of a controversial 20-year-old theory of consciousness claims that consciousness derives from deeper level, finer scale activities inside brain neurons. The recent discovery of quantum vibrations in "microtubules" inside brain neurons corroborates this theory, according to review authors. They suggest that EEG rhythms (brain waves) also derive from deeper level microtubule vibrations, and that from a practical standpoint, treating brain microtubule vibrations could benefit a host of mental, neurological, and cognitive conditions.
How metabolism, brain activity are linked: Study sheds light on why diet may help control seizures in epilepsy patients A new study shows a direct link between metabolism in brain cells and their ability to signal information. The research may explain why the seizures of many epilepsy patients can be controlled by a
Brain regions 'tune' activity to enable attention The brain appears to synchronize the activity of different brain regions to make it possible for a person to pay attention or concentrate on a task, scientists have learned.
Spirituality, religion may protect against major depression by thickening brain cortex A thickening of parts of the brain cortex associated with regular meditation or other spiritual or religious practice could be the reason those activities guard against depression – particularly in people who are predisposed to the disease, according to new research. Researchers studied 130 subjects and found that those who highly valued spirituality showed thicker portions of brain cortices that may protect against depression -- especially in those at high risk for the disease.

When doctor's visit is a guilt trip Some patients react to a shaming encounter with a health provider in a way that promotes health while others turn to lying or avoidance. Why? What makes the difference?
Head injuries triple long-term risk of early death Survivors of traumatic brain injuries (TBI) are three times more likely to die prematurely than the general population, often from suicide or fatal injuries, finds a study. A TBI is a blow to the
Heavy drinking in middle age may speed memory loss by up to six years in men Middle-aged men who drink more than 36 grams of alcohol, or two and a half US drinks per day, may speed their memory loss by up to six years later on, according to a study published. On the other hand, the study found no differences in memory and executive function in men who do not drink, former drinkers and light or moderate drinkers. Executive function deals with attention and reasoning skills in achieving a goal.
