Researchers use functional MRI to understand how the brain functions

University of Nevada, Reno neuroscientists are working with Renown Health to bring new research capabilities to northern Nevada. The research group, led by University Professor of Psychology Michael Webster, has purchased equipment that augments the existing 3T magnetic resonance imaging (MRI) technology at Renown Health for studies of human brain function.

Abstinence-induced changes in the brain could help predict relapse in smokers

Quitting smoking sets off a series of changes in the brain that Penn Medicine researchers say may better identify smokers who will start smoking again—a prediction that goes above and beyond today's clinical or behavioral tools for assessing relapse risk.

UC Berkeley scientists reveal how humans have excelled at 'relational reasoning'

When it comes to getting out of a tricky situation, we humans have an evolutionary edge over other primates. Take, as a dramatic example, the Apollo 13 voyage in which engineers, against all odds, improvised a chemical filter on a lunar module to prevent carbon dioxide buildup from killing the crew.

Experts report three key topics that may make difference in the battle against Alzheimer's disease

Detection, prevention, and preclinical treatment are three key areas that may make a difference in the battle to reduce the rapid rise of new Alzheimer's disease (AD) cases every year. These three topics are the focus of an important new supplement to the Journal of Alzheimer's Disease.

Frontal lesions predict better improvement in people with spatial neglect after prism therapy

Stroke researchers have found that the presence of frontal lesions predicts better functional improvement in individuals with spatial neglect who received prism adaptation therapy. "Integrity of medial temporal structures may predict better improvement of spatial neglect with prism adaptation treatment" was published in September in the Neuroimaging and Rehabilitation Special Issue of Brain Imaging & Behavior.

Neuroimaging markers have synergistic effect on cognitive decline

The Alzheimer disease neuroimaging markers β-amyloid and neurodegeneration have synergistic effects on the rate of cognitive decline in clinically normal people, research shows.

Variants of ASIC1a gene appear to be associated with panic disorder

Panic disorder is a severe form of anxiety in which the affected individual feels an abrupt onset of fear, often accompanied by profound physical symptoms of discomfort. Scientists have known from studying twins that genes contribute to the risk of panic disorder, but very little is known about which specific genes are involved.

Different forms of ASIC1a gene associated with panic disorder

Panic disorder is a severe form of anxiety in which the affected individual feels an abrupt onset of fear, often accompanied by profound physical symptoms of discomfort.

DTI may play role in assessing brain damage in early Alzheimer's disease

Changes in brain connections visible on MRI could represent an imaging biomarker of Alzheimer's disease, according to a new study presented today at the annual meeting of the Radiological Society of North America (RSNA).

PET/CT may improve differentiation of PTSD from MTBI

Hybrid imaging with positron emission tomography and computed tomography (PET/CT) in the pituitary region of the brain is a promising tool for differentiating military veterans with post-traumatic stress disorder (PTSD) from those with mild traumatic brain injury (MTBI), according to a new study presented at the annual meeting of the Radiological Society of North America (RSNA).

Cognitive test battery developed to measure impact of spaceflight stressors on cognitive performance

Space is one of the most demanding and unforgiving environments. Human exploration of space requires astronauts to maintain consistently high levels of cognitive performance to ensure mission safety and success, and prevent potential errors and accidents. Despite the importance of cognitive performance for mission success, little is known about how cognition is affected by prolonged spaceflight, and what aspects of cognition are primarily affected.

Lewy body dementia: 10 things people need to know

The recent news that the brain of actor/comedian Robin Williams showed signs of diffuse Lewy body disease has created more interest and coverage in this widely under-diagnosed condition than ever before.

Successful antipsychotic treatment may alter striatal connectivity

Connectivity within the striatum changes as psychotic symptoms improve in patients treated with second-generation antipsychotics, a study shows.

Anxiety can accelerate conversion to Alzheimer's disease for people with mild cognitive impairment

People with mild cognitive impairment (MCI) are at increased risk of converting to Alzheimer's disease within a few years, but a new study warns the risk increases significantly if they suffer from anxiety.

Olympus to host fifth annual neuroimaging symposium in conjunction with 2014 annual meeting of the Society for Neuroscience

Olympus is hosting its fifth annual neuroimaging symposium in conjunction with the 2014 annual meeting of the Society for Neuroscience (SfN) on Monday, November 17 at 6:30pm in Washington DC. The Olympus Neuroimaging Symposium and reception will be held at the Marriott Marquis Washington, DC, 901 Massachusetts Avenue NW, in the Capitol and Congress ballrooms. It is open to all media and registered SfN attendees.

VTT develops innovative magnetometer for applications such as medical imaging

VTT Technical Research Centre of Finland has developed an innovative magnetometer that can replace conventional technology in applications such as neuroimaging, mineral exploration and molecular diagnostics. Its manufacturing costs are between 70 and 80 per cent lower than those of traditional technology, and the device is not as sensitive to external magnetic fields as its predecessors. The design of the magnetometer also makes it easier to integrate into measuring systems.

Butler neuropsychologist studies OCD patients undergoing gamma knife radiosurgery

Supported by a $750,000 K23 Career Development Award from the National Institutes of Health, Butler Hospital neuropsychologist Nicole McLaughlin, PhD, is conducting a first-of-its-kind study of patients with obsessive-compulsive disorder (OCD) undergoing gamma knife radiosurgery.

Study: Engaging brain areas linked to 'off-task' mental activities can boost performance

To solve a mental puzzle, the brain's executive control network for externally focused, goal-oriented thinking must activate, while the network for internally directed thinking like daydreaming must be turned down to avoid interference – or so we thought.

Early brain imaging studies may help prevent vascular diseases

Future prevention and treatment strategies for vascular diseases may lie in the evaluation of early brain imaging tests long before heart attacks or strokes occur, according to a systematic review conducted by a team of cardiologists, neuroscientists, and psychiatrists from Icahn School of Medicine at Mount Sinai and published in the October issue of JACC Cardiovascular Imaging.

Internal calorie counter evaluates food based on its caloric density, shows neuroimaging study

As you glance over a menu or peruse the shelves in a supermarket, you may be thinking about how each food will taste and whether it's nutritious, or you may be trying to decide what you're in the mood for.
