New research reveals grid cells in human brain provide a cognitive, spatial map

'Grid cells' that act like a spatial map in the brain have been identified for the first time in humans, according to new research by UCL scientists which may help to explain how we create internal maps of new environments.

New computational model helps understand how dopamine medications affect non-motor functions

A new brain-based computational model is helping to understand how Parkinson's disease and dopamine medications-used to treat motor symptoms caused by the disease- can affect learning and attention.

Research shows brain abnormalities develop years before Parkinson's symptoms appear

Scientists who have identified brain networks damaged in Parkinson's disease have new evidence that these systems become abnormal a few years before symptoms appear. And what's more, parts of the network appear to respond in a last ditch attempt to rescue the brain.

Cognitive scientists link ancient questions to newest emerging fields of research in various areas

Cognitive Science represents the exploration of the human mind in the hope of answering some of humanity's oldest questions, from the origin of thought to the nature of knowledge.

Finding supports modularity of mind theory

Recognizing faces is an important social skill, but not all of us are equally good at it. Some people are unable to recognize even their closest friends (a condition called prosopagnosia), while others have a near-photographic memory for large numbers of faces.

New research at Rhode Island Hospital identifies a treatment for glioblastomas

New research at Rhode Island Hospital has identified a treatment in animal models for glioblastomas - deadly brain tumors which, once diagnosed, offer a poor prognosis and relatively short life expectancy.

Interdisciplinary nature of biological research triggers changes to JBC's publishing policies

The Journal of Biological Chemistry's editors are unveiling this week a number of changes to the journal's publishing policies. They say the changes are in response to the increasingly interdisciplinary nature of biological research and will help the journal better meet the evolving needs of the scientific community.

People with "mental lapses" more likely to have Alzheimer's disease

Older people who have "mental lapses," or times when their thinking seems disorganized or illogical or when they stare into space, may be more likely to have Alzheimer's disease than people who do not have these lapses, according to a study published in the January 19, 2010, print issue of Neurology-, the medical journal of the American Academy of Neurology.

AstraZeneca and Dako Denmark A/S enter into collaboration agreement

AstraZeneca and Dako Denmark A/S announced today that they have entered into a collaboration agreement to develop companion diagnostic tests for multiple AstraZeneca oncology projects, including biologics and small molecules, in various stages of discovery and development.

Organization of the brain's dictionary

Two hundred years ago, archaeologists used the Rosetta Stone to understand the ancient Egyptian hieroglyphs. Now, a team of Carnegie Mellon University scientists has discovered the beginnings of a neural Rosetta Stone. By combining brain imaging and machine learning techniques, neuroscientists Marcel Just and Vladimir Cherkassky and computer scientists Tom Mitchell and Sandesh Aryal determined how the brain arranges noun representations. Understanding how the brain codes nouns is important for treating psychiatric and neurological illnesses.

Neurosurgical journals influence neurosurgeons and their patients

A compendium of articles in the Journal of Neurosurgery (JNS) provides evidence that specialty medical journals are not only an invaluable resource to physicians and researchers, but to the media and public. Clinical and basic science papers do not have to be published in large, high-impact publications to garner attention, and in fact when it comes to specialized areas of medicine such as neurosurgery, publications devoted to the subspecialty produce many citation classics. "Citation classic" is a term given to articles that have been cited more than 400 times.

Study reveals link between serotonin receptor number and antidepressant treatment

An excess of one type of serotonin receptor in the center of the brain may explain why antidepressants fail to relieve symptoms of depression for 50 percent of patients, a new study from researchers at Columbia University Medical Center shows.

Dopamine replacement therapy causes brain dysfunction in patients with Parkinson disease, study says

People with Parkinson's Disease are more likely to display abnormal social behaviour and make poor decisions in ambiguous circumstances if they are pathological gamblers, according to research in the January issue of the European Journal of Neurology.

New research shows migraine and depression may share common genetic pathways

New research shows that migraine and depression may share a strong genetic component. The research is published in the January 13, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Portugal life scientist awarded ERC's Advanced Investigator Grant

Zachary Mainen, coordinator of the Champalimaud Foundation Neuroscience Programme at the IGC, has become one of the most recent winners of the prestigious and highly competitive European Research Council grants, to the value of 2.3 million euro, for a period of five years. This grant, which recognises Mainen's contribution to the Neuroscience field, will be used to elucidate the biological role of the neurotransmitter serotonin.

New findings may yield novel therapies for chronic neurodegenerative diseases

We all have at one time or another experienced the typical signs of an infection: the fever, the listlessness, the lack of appetite. They are orchestrated by the brain in response to circulating cytokines, the signaling molecules of the immune system. But just how cytokines' reach extends beyond the almost impenetrable blood-brain barrier has been the topic of much dispute.

Findings may pave way for significant advancements in cochlear implant technology for hearing loss

Loss of spiral ganglion neurons or hair cells in the inner ear is the leading cause of congenital and acquired hearing impairment. Researchers at the University of California, San Diego, School of Medicine and the National Institutes of Health found that Sox2, a protein that regulates stem cell formation, is involved in spiral ganglion neuron development. The study was published in the January 13 issue of the Journal of Neuroscience.

Olfactory dysfunction may serve as an early diagnostic tool for Alzheimer's disease

A study published in the January 13, 2010 issue of the Journal of Neuroscience links a loss of smell function in Alzheimer's disease (AD) model animals with amyloid β (protein) accumulation in the brain, a distinguishing hallmark of Alzheimer's disease. Research conducted by NYU Langone Medical Center suggests that olfactory dysfunction, a common symptom of AD, may serve as an early diagnostic tool for the disease.
