Gene variant affects brain function long before brain begins accumulating amyloid: Study

People with a known, high risk for Alzheimer's disease develop abnormal brain function even before the appearance of telltale amyloid plaques that are characteristic of the disease, according to a new study.

New study shows how meditators don't ponder pain

Zen meditation has many health benefits, including a reduced sensitivity to pain. According to new research from the Universit- de Montr-al, meditators do feel pain but they simply don't dwell on it as much. These findings, published in the month's issue of Pain, may have implications for chronic pain sufferers, such as those with arthritis, back pain or cancer.

New brain imaging technique can trace effects of SYN115 drug in Parkinson's disease

Neuroscientists using a new brain imaging technique could see an investigational drug for Parkinson's disease get into a patient's brain and affect blood flow in several key structures, an indicator the drug may be effective.

Functional MRI reveals effectiveness of acupuncture in relieving pain

Using functional magnetic resonance imaging (fMRI), researchers have captured pictures of the brain while patients experienced a pain stimulus with and without acupuncture to determine acupuncture's effect on how the brain processes pain. Results of the study, which the researchers say suggest the effectiveness of acupuncture, were presented today at the annual meeting of the Radiological Society of North America (RSNA).

Combination of caffeine and glucose can improve cognitive performance: Study

The combination of caffeine and glucose can improve the efficiency of brain activity, according to a recent study in which functional magnetic resonance imaging was used to identify the neural substrate for the combined effects of these two substances.

Aging changes how people view themselves and others through 'mind wandering'

Neuroscientists at Georgetown University Medical Center can now show, using functional MRI images, why it is that behavior in children and young adolescents veers toward the egocentric rather than the introspective.

fMRI predicts response to 'talk therapy' in patients with pediatric anxiety disorder

A brain scan with functional MRI (fMRI) is enough to predict which patients with pediatric anxiety disorder will respond to "talk therapy," and so may not need to use psychiatric medication, say neuroscientists from Georgetown University Medical Center.

Research on fruit flies reveal novel human pain gene

While it has become clear in recent years that susceptibility to pain has a strong inherited component, very little is known about actual "pain genes" and how they work. In the November 12th issue of Cell, researchers at Children's Hospital Boston and their collaborators report on a novel human pain gene. People with minor variations in this gene showed clear differences in susceptibility to acute heat pain and chronic back pain.

Full-term babies are born with key collection of networks already formed in their brains: Study

Full-term babies are born with a key collection of networks already formed in their brains, according to new research that challenges some previous theories about the brain's activity and how the brain develops. The study is published today in the journal Proceedings of the National Academy of Sciences.

NSF awards Rutgers $1.82M grant to acquire Siemens Trio 3T MRI scanner

The last couple decades have seen a virtual renaissance of neuroscience discovery, largely aided by the advanced technology of functional magnetic resonance imaging (fMRI).

Researchers suggest gene therapy may treat patients with major depression

In a report published in the Oct. 20 issue of Science Translational Medicine, researchers at NewYork-Presbyterian Hospital/Weill Cornell Medical Center say animal and human data suggest gene therapy to the brain may be able to treat patients with major depression who do not respond to traditional drug treatment.

Researchers to contribute to brain circuit mapping in Human Connectome Project

Thirty-three researchers at nine institutions will contribute to the Human Connectome Project (http://www.humanconnectome.org/consortia). Using powerful, custom-built brain scanners, a supercomputer, new brain analysis techniques and other state-of-the-art resources, they will trace the anatomical 'wires' that interconnect thousands of different regions of the human brain's gray matter.

MRI brain scans can accurately predict young person's age

Using MRI technology and mathematical analysis, researchers at Oregon Health & Science University and Washington University in St. Louis are now able to accurately predict a young person's age simply by studying their brain scans. The research, which will likely have several clinical applications, including assessment and diagnosis, is published in the current edition of the journal Science.

Researchers to discuss brain's secrets at neuroscience conference

Top brain researchers from around the world will be in Milwaukee, Sept, 16-19, 2010, for a neuroscience conference focused on gaining insights into the brain's inner workings to better understand how the brain thinks, how the brain develops, and how the brain is altered by neurological diseases and how it responds to treatment.

Emergency department visits for concussions in young athletes on the rise

A new study from Hasbro Children's Hospital finds visits to emergency departments for concussions that occurred during organized team sports have increased dramatically over a 10-year period, and appear to be highest in ice hockey and football. The number of sports-related concussions is highest in high school-aged athletes, but the number in younger athletes is significant and rising.

Specific type of neurons determine frightening stimulus reaction: Research

Fear can make you run, it can make you fight, and it can glue you to the spot. Scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy and GlaxoSmithKline in Verona, Italy, have identified not only the part of the brain but the specific type of neurons that determine how mice react to a frightening stimulus.

Unavoidable breakdowns in brain connections as we age: Study

It's unavoidable: breakdowns in brain connections slow down our physical response times as we age, a new study suggests.

Functional MRI can be used to assess tumor viability

Pancreatic ductal adenocarcinoma (the disease commonly referred to as pancreatic cancer) carries the worst prognosis of any cancer. As current treatments offer minimal benefit, entirely new approaches are needed. Given the success of local therapies, as opposed to intravenous systemic therapies, for liver diseases (such as hepatocellular carcinoma), it is thought that similar local therapies may benefit patients with pancreatic cancer. To develop such therapies, it would be useful to devise targets that are easy to obtain and can indicate the efficacy of these new therapies in models of pancreatic cancer.

Blind people and people with vision think about manipulating tools in same brain regions

Blind people think about manipulating tools in the same regions of the brain as do people who can see, according to a new study. The researchers say this adds to evidence that the brain has a fairly defined organization, while still being able to adapt to unusual conditions, such as not having any vision.
