Set-shifting and the on-line processing of relative clauses in Parkinson's Disease

The study of the neural basis of language has largely focused on regions in the cortex - the outer brain layers thought by many researchers to have expanded during human evolution.

New brain visualization technology enables removal of fist-sized tumor

A new technology involving the fusion of four different types of images into a 3-D map of a patient's brain has helped University of Cincinnati (UC) specialists successfully remove a fist-sized tumor from the brain of an Indiana woman.

Brain imaging (MRI/PET) bring us closer to earlier detection of Alzheimer's

Changes in the brain measured with MRI and PET scans, combined with memory tests and detection of risk proteins in body fluids, may lead to earlier and more accurate diagnosis of Alzheimer's, according to new research reported today at the Alzheimer's Association 2009 International Conference on Alzheimer's Disease (ICAD 2009) in Vienna.

Results from trials of DHA in Alzheimer's and age-related cognitive decline

Results from two large studies using DHA, an omega 3 fatty acid, were reported today at the Alzheimer's Association 2009 International Conference on Alzheimer's Disease (ICAD 2009) in Vienna.

Research pinpoints difference in the way children with autism learn new behaviors

Researchers from the Kennedy Krieger Institute and Johns Hopkins University School of Medicine have collaborated to uncover important new insights into the neurological basis of autism. Their new study, published in the journal Nature Neuroscience, examined patterns of movement as children with autism and typically developing children learned to control a novel tool.

Neuroimaging shows how we recognize right and wrong

A recent neuroimaging study reveals that the ability to distinguish true from false in our daily lives involves two distinct processes. Previous research relied heavily on the premise that true and false statements are both processed in the left inferior frontal cortex.

New diagnostic technique detects possible Alzheimer's biomarker in blood

A new diagnostic technique which may greatly simplify the detection of Alzheimer's disease has been discovered by researchers at McGill University and the affiliated Lady Davis Institute for Medical Research at Montreal's Jewish General Hospital (JGH).

Neuroscientists watch memories form in real time

Our ability to form long-term memories depends on cells in the brain making strong connections with each other. Yet while it's not well understood how those connections are made, lost or changed, the process is known to involve the movement of the AMPA receptor protein to and from those neuronal connections.

Comprehensive review on sulfonylureas in the latest issue of Diabetic Hypoglycemia

The latest issue of the online journal Diabetic Hypoglycemia features an authoritative review on sulfonylureas by Professor Ian Campbell, a leading expert in oral hypoglycemia therapy.

The colourful world of synesthesia

David Eagleman, Ph.D will explore the brilliant scope of the human mind in his forthcoming lecture at the University of Sydney on the perplexing cognitive condition, Synesthesia.

MRI analysis software helps identify early Alzheimer’s disease

Analyzing MRI studies of the brain with software developed at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital (MGH) may allow diagnosis of Alzheimer's disease and of mild cognitive impairment, a lesser form of dementia that precedes the development of Alzheimer's by several years.

Smoking makes it harder for brain blood flow to recover from long-term heavy drinking

Alcohol-use disorders (AUDs) can damage the brain, particularly the frontal and parietal cortices, although this damage is at least partially reversible with sustained abstinence from alcohol. Chronic smoking is extremely common among individuals with AUDs.

New insight into brain mechanisms associated with reading

A new study provides direct experimental evidence that a brain region important for reading and word recognition contains neurons that are highly selective for individual real words.

New insight into the neurological basis of autism

In the first neuroimaging study to examine motor execution in children with autism, researchers at the Kennedy Krieger Institute have uncovered important new insight into the neurological basis of autism.

Early brain activity sheds new light on the neural basis of reading

Most people are expert readers, but it is something of an enigma that our brain can achieve expertise in such a recent cultural invention, which lies at the interface between vision and language.

Better understanding of the brain basis of reading

Most people are expert readers, but it is something of an enigma that our brain can achieve expertise in such a recent cultural invention, which lies at the interface between vision and language.

Neurodegenerative diseases target healthy brain's intrinsic networks

New research suggests that neurodegenerative diseases are neither diffuse nor random but specifically target large-scale functional networks in the human brain.

Neurodegeneration study reveals targets of destruction

Scientists are reporting the strongest evidence to date that neurodegenerative diseases target and progress along distinct neural networks that normally support healthy brain function.

Researchers aim to determine if specific brain circuits and pathways might be responsible for wisdom

Researchers at the University of California, San Diego School of Medicine have compiled the first-ever review of the neurobiology of wisdom – once the sole province of religion and philosophy.

Brain scan-assisted diagnosis for post-traumatic stress disorder a step closer to reality

Florence, Italy: Preliminary research examining the difference in brain activity between soldiers with post-traumatic stress disorder and those without it moves scientists a step closer to the possibility of being able one day to use brain scans to help diagnose the condition.
