Supercomputer Simulations Of Blast Waves On The Brain Studied To Improve Helmets
2012-11-15 12:46:32

Sandia National Laboratories Researchers at Sandia National Laboratories and the University of New Mexico are comparing supercomputer simulations of blast waves on the brain with clinical studies of veterans suffering from mild traumatic brain injuries (TBIs) to help improve helmet designs. Paul Taylor and John Ludwigsen of Sandia´s Terminal Ballistics Technology Department and Corey Ford, a neurologist at UNM´s Health Sciences Center, are in the final year of a four-year...

April Flowers for redOrbit.com - Your Universe Online Alex Seaman is 20 years old, and for the last year and a half, he's been a patient at the Royal Hospital for Neuro-disability. He is awake and even has his eyes open at times, but Alex has no apparent awareness and is unable to talk or respond with his body. Alex suffered a severe head injury last April. He had been out celebrating a friend's 18th birthday and missed his bus stop. The bus was still moving when he jumped off and hit...

How The Brain Affects Quick Judgments In Social Settings
2012-11-13 12:51:09

April Flowers for redOrbit.com - Your Universe Online We make snap judgments about other people all the time, whether we like to admit it or not. In speed dating, this is especially true because we are deciding someone's romantic potential in relatively few seconds. How we make those fast decisions is not very well understood, however. A research team from the California Institute of Technology (CALTECH) and Trinity College, Dublin has found that people make such speed-dating...

Meditation Has Lasting Emotional Benefits Says Study
2012-11-13 11:30:10

April Flowers for redOrbit.com - Your Universe Online Meditation has been part of the human experience for at least 5,000 years. Our first written records of the ancient art are found in Indian scriptures, called tantras. Around 2,500 years ago, Siddhartha Gautma, commonly called Buddha, began teaching meditation as a road to enlightenment. However, it wasn´t until the 1960s that Western professors and researchers began studying the effects of mediation in earnest. Participating in...

Math Can Really Hurt
2012-11-02 04:01:41

Brett Smith for redOrbit.com - Your Universe Online Some lucky people have a proclivity for number crunching and difficult equations, but for many of us the idea of performing complex calculations is more horrifying than a Friday the 13th movie marathon. And, like Jason Voorhees´ two-foot machete plunging into his victim´s abdomen – the personal anxiety surrounding an impending math exam can actually cause people to feel physical pain, according to new research from the...

Human Brain Can Only Process So Much Information At Once
2012-10-31 05:07:15

April Flowers for redOrbit.com - Your Universe Online Even the most intelligent, complex brains can be taken by a swindler's story, a new study from Case Western Reserve University shows, even stories that prove false upon a second look. The new study, published online in the journal NeuroImage, reveals that when the brain fires up the network of neurons that allows a person to empathize, the network used for analysis is suppressed. Our ability to appreciate the human cost of our action...

Researchers Hunt For Mechanisms Of Hypnosis To Better Understand How It Works On Some, And Not On Others
2012-10-04 16:19:47

Alan McStravick for redOrbit.com - Your Universe Online From the Greek word hypnos, meaning “sleep”, Hypnotherapists are trained in utilizing exercises necessary in bringing about a sense of deep relaxation and an altered state of consciousness. Once in this state, a patient is typically responsive to an idea or image but the therapist isn´t in control of the patient´s mind or free will. By undergoing hypnosis, the patient can learn how to master their own states of...

You already know it's hard to balance your checkbook while simultaneously reflecting on your past. Now, investigators at the Stanford University School of Medicine – having done the equivalent of wire-tapping a hard-to-reach region of the brain – can tell us how this impasse arises. The researchers showed that groups of nerve cells in a structure called the posterior medial cortex, or PMC, are strongly activated during a recall task such as trying to remember whether you had...

State-of-the-art imaging technology for biomarker development explored in a supplement to Journal of Alzheimer's Disease Alzheimer's disease (AD) is one of the most common brain disorders, with an estimated 35 million people affected worldwide. In the last decade, research has advanced our understanding of how AD affects the brain. However, diagnosis continues to rely primarily on neuropsychological tests which can only detect the disease after clinical symptoms begin. In a supplement to...
