Fish oil may have positive effects on mood, alcohol craving, new study shows

INDIANAPOLIS – Omega 3 fatty acids may be beneficial for more than just the heart. Research at the Indiana University School of Medicine disclosed at a molecular level a potential therapeutic benefit between these dietary supplements, alcohol abuse and psychiatric disorders.

New imaging method allows Stanford scientists to identify specific mental states

STANFORD, Calif. — New clues to the mystery of brain function, obtained through research by scientists at the Stanford University School of Medicine, suggest that distinct mental states can be distinguished based on unique patterns of activity in coordinated "networks" within the brain. These networks consist of brain regions that are synchronously communicating with one another. The Stanford team is using this network approach to develop diagnostic tests in Alzheimer's disease and other brain disorders in which network function is disrupted.

Tinted specs offer real migraine relief, says fMRI study

Los Angeles, CA (May 26, 2011) – Precision tinted lenses have been used widely to reduce visual perceptual distortions in poor readers, and are increasingly used for migraine sufferers, but until now the science behind these effects has been unclear. Now research published in the journal Cephalalgia, published by SAGE, uses functional magnetic resonance imaging (fMRI) for the first time to suggest a neurological basis for these visual remedies.

Researchers evaluate red wine compound for treating concussions in pro boxers

DALLAS – May 26, 2011 – UT Southwestern Medical Center researchers are engaging the help of professional boxers and trainers to study whether a component in red wine and grapes could help reduce the short- and long-term effects of concussions.

Reindeer see a weird and wonderful world of ultraviolet light

Researchers have discovered that the ultraviolet (UV) light that causes the temporary but painful condition of snow blindness in humans is life-saving for reindeer in the arctic.

'I can hear a building over there' -- researchers study blind people's ability to echolocate

Everybody has heard about echolocation in bats and dolphins. These creatures emit bursts of sounds and listen to the echoes that bounce back to detect objects in their environment. What is less well known is that people can echolocate, too. In fact, there are blind people who have learned to make clicks with their mouths and to use the returning echoes from those clicks to sense their surroundings. Some of these people are so adept at echolocation that they can use this skill to go mountain biking, play basketball, or navigate unknown environments.

Scientists trick the brain into Barbie-doll size

Imagine shrinking to the size of a doll in your sleep. When you wake up, will you perceive yourself as tiny or the world as being populated by giants? Researchers at Karolinska Institutet in Sweden may have found the answer.

'I can hear a building over there'

It is common knowledge that bats and dolphins echolocate, emitting bursts of sounds and then listening to the echoes that bounce back to detect objects. What is less well-known is that people can echolocate too. In fact, there are blind people who have learned to make clicks with their mouths and to use the returning echoes from those clicks to sense their surroundings. Some of these individuals are so adept at echolocation that they can use this skill to navigate unknown environments, and participate in activities such as mountain biking and basketball.

New University of Houston research study links job stress in teachers to student achievement

After 17 years of researching traumatic stress with war-afflicted populations (veterans and civilians) and job stress in the medical profession, Teresa McIntyre, a research professor in the department of psychology and the Texas Institute for Evaluation, Measurement and Statistics (TIMES), at the University of Houston (UH), decided to study another high risk occupation, middle school teachers in seventh and eighth grade.

Thoughts that win

Back in high school, on the soccer field, poised to take a crucial penalty kick, "I always had a lot of thoughts going on in my head; I think most people do" says sports psychologist Antonis Hatzigeorgiadis. "I was setting the ball and planning my shot; I was the captain and never missed those types of shots; then I had that thought striking me that it was not going to be good. I knew I was going to miss," he recalls, "and I did miss." Even then, he could see that his mind had a big effect on his body.

Unique nerve-stimulation treatment proves effective against drug-resistant epilepsy

Medications are the mainstay of treatment for epilepsy, but for a considerable number of patients — estimated to be as many as 1 million in the U.S. — drugs don't work. These patients suffer from a type of epilepsy known as refractory or drug-resistant epilepsy, in which drugs can't control their seizures.

But at an epilepsy conference last month, Dr. Christopher DeGiorgio, a UCLA professor of neurology, presented the results of a non-invasive, non-pharmaceutical treatment that shows promise in controlling seizures.

Pitt team recreates brain cell networks with new view of activity behind memory formation

PITTSBURGH—University of Pittsburgh researchers have reproduced the brain's complex electrical impulses onto models made of living brain cells that provide an unprecedented view of the neuron activity behind memory formation.

Violent video games reduce brain response to violence and increase aggressive behavior

Participants who had already spent a lot of time playing violent video games before the study showed small brain response to the violent photos, regardless of which type of game they played in the lab.

Autism changes molecular structure of the brain, UCLA study finds

For decades, autism researchers have faced a baffling riddle: how to unravel a disorder that leaves no known physical trace as it develops in the brain.

Now a UCLA study is the first to reveal how the disorder makes its mark at the molecular level, resulting in an autistic brain that differs dramatically in structure from a healthy one. Published May 25 in the advance online edition of Nature, the findings provide new insight into how genes and proteins go awry in autism to alter the mind.
