Psychopathy Linked to Specific Structural Abnormalities in the Brain
New research provides the strongest evidence to date that psychopathy is linked to specific structural abnormalities in the brain. The study, published in Archives of General Psychiatry and led by researchers at King’s College London is the first to confirm that [Read More]
New MRI Technique May Predict Progress of Dementias
Computer Modeling Supports Theory That Many Dementias Spread Like Prion Diseases. A new technique for analyzing brain images offers the possibility of using magnetic resonance imaging (MRI) to predict the rate of progression and physical path of many degenerative brain [Read More]
Brain Wiring a No-Brainer?
Scans reveal astonishingly simple 3D grid structure. The brain appears to be wired more like the checkerboard streets of New York City than the curvy lanes of Columbia, Md., suggests a new brain imaging study. The most detailed images, to date, reveal a pervasive 3D grid [Read More]
How Genes Organize the Surface of the Brain
The first atlas of the surface of the human brain based upon genetic information has been produced by a national team of scientists, led by researchers at the University of California, San Diego School of Medicine and the VA San Diego Healthcare System. The work is [Read More]
Researchers Use Nanoparticles, Magnetic Current to Damage Cancerous Cells in Mice
Using nanoparticles and alternating magnetic fields, University of Georgia scientists have found that head and neck cancerous tumor cells in mice can be killed in half an hour without harming healthy cells. The findings, published recently in the journal Theranostics, mark [Read More]
Scientists Develop First Snap Shot of Tiny Brain Tumors
Cancer Research UK scientists have developed a technique they believe could be used to detect tiny secondary tumors in the brain, a process that is currently impossible, according to research published in PNAS, Monday. The scientists at Cancer Research UK’s Gray Institute [Read More]
Low Levels of Omega-3 Fatty Acids May Cause Memory Problems
A diet lacking in omega-3 fatty acids, nutrients commonly found in fish, may cause your brain to age faster and lose some of its memory and thinking abilities, according to a study published in the February 28, 2012, print issue of Neurology, the medical journal of the [Read More]
Drinking Alcohol Shrinks Critical Brain Regions in Genetically Vulnerable Mice
New evidence that receptors for brain’s ‘reward’ chemical provide protection. Brain scans of two strains of mice imbibing significant quantities of alcohol reveal serious shrinkage in some brain regions — but only in mice lacking a particular type of receptor for [Read More]
Working Memory and the Brain
Visual working memory not as specialized in the brain as visual encoding, study finds. Researchers have long known that specific parts of the brain activate when people view particular images. For example, a region called the fusiform face area turns on when the eyes glance [Read More]
Magic Mushrooms’ Effects Illuminated in Brain Imaging Studies
Brain scans of people under the influence of the psilocybin, the active ingredient in magic mushrooms, have given scientists the most detailed picture to date of how psychedelic drugs work. The findings of two studies being published in scientific journals this week [Read More]
