Study points to molecular origin of neurodegenerative disorders, including Huntington's disease
New research from the University of North Carolina at Chapel Hill School of Medicine points to the possible molecular origin of at least nine human diseases of nervous system degeneration.   view more (2005-09-26)

Prozac's target revealed
Researchers at Cold Spring Harbor Laboratory on Long Island have identified which among several different kinds of cells in the brain is the chief target of the widely prescribed antidepressant Prozac.   view more (2006-05-16)

Researchers find molecule that may hold key to learning and memory
Independent research teams from Harvard Medical School and Children's Hospital Boston have identified a master protein that sheds light on one of neurobiology's biggest mysteries-how neurons change as a result of individual experiences.   view more (2006-02-22)

Optics tests for early Alzheimer's diagnosis make significant advances
Providing an update on progress and new findings on his optical tests for the early detection of Alzheimer's disease, Lee Goldstein of Brigham and Women's Hospital and Harvard Medical School will describe dramatic new developments in the technology during a plenary talk at Frontiers in Optics, the... view more (2006-10-04)

Deadly infectious entity of prions discovered
The mysterious, highly infectious prions, which cause the severe destruction of the brain that characterizes "mad cow disease" and several human brain degenerative disorders, can be rendered harmless in the laboratory by a slight alternation of the three-dimensional conformation or shape... view more (2005-06-10)

Dopamine imbalances cause sleep disorders in animal models of Parkinson's disease and schizophrenia
Neuroscientists at Duke University Medical Center working with genetically engineered mice have found that the brain chemical dopamine plays a critical role in regulating sleep and brain activity associated with dreaming.   view more (2006-10-11)

Stem Cell Activity Deciphered in the Aging Brain
Neurobiologists have discovered why the aging brain produces progressively fewer new nerve cells in its learning and memory center. The scientists said the finding, made in rodents, refutes current ideas on how long crucial "progenitor" stem cells persist in the aging brain.   view more (2006-12-19)

Depression linked to previously unknown dopamine regulator
Researchers from Harvard Medical School have found a molecule that is unexpectedly involved in dopamine signaling, and in a manner that supports the potential of dopamine as an alternative target for treating depression.   view more (2005-07-29)

The CReSA is working on a new strategy to combat spongiforms
Researchers at the Animal Health Research Centre (CReSA) are developing immunotherapeutical strategies against diseases produced by prion, such as Bovine Spongiform Encephalitis.   view more (2006-11-01)

Neuronal Receptor Response May Help Explain Alzheimer's Memory Loss
Based on laboratory research, scientists at Georgetown University Medical Center have a new theory as to why people with Alzheimer's disease have trouble performing even the simplest memory tasks, such as remembering a family member's name.   view more (2006-02-13)

Alteration of brain protein regulates learning
Researchers at UT Southwestern Medical Center have identified a biochemical switch that affects how neurons fire in a part of the brain associated with learning, findings that may aid in understanding schizophrenia and Alzheimer's disease.   view more (2005-08-18)

Human cerebellum and cortex age in very different ways
Researchers have found that the two primary areas of the human brain appear to age in radically different ways: The cortex used in higher-level thought undergoes more extensive changes with age than the cerebellum, which regulates basic processes such as heartbeat, breathing and balance.   view more (2005-08-02)

Nerve cells derived from stem cells and transplanted into mice may lead to improved brain treatments
Scientists at the Burnham Institute for Medical Research have, for the first time, genetically programmed embryonic stem (ES) cells to become nerve cells when transplanted into the brain, according to a study published today in The Journal of Neuroscience.   view more (2008-06-25)

Mad cow protein aids creation of brain cells
Few conditions are more detrimental to human brains than the one popularly referred to as mad cow disease.   view more (2006-02-14)

Green tea compounds beat OSA-related brain deficits
Chemicals found in green tea may be able to stave off the cognitive deficits that occur with obstructive sleep apnea (OSA), according to a new study published in the second issue for May of the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.   view more (2008-05-15)

Scientists develop a new way to target Alzheimer's disease
The pathological embrace between two proteins plays a key role in the development of Alzheimer's disease by triggering the formation of neuron-killing plaques of amyloid beta protein. Now a group of scientists at NYU School of Medicine have devised a way to reduce amyloid beta deposition by... view more (2006-12-05)

Restricting diet may reverse early-stage Parkinson's disease
A new Oregon Health & Science University and Portland Veterans Affairs Medical Center study suggests that early-stage Parkinson's disease patients who lower their calorie intake may boost levels of an essential brain chemical lost from the neurodegenerative disorder.   view more (2005-11-16)

RNA-associated introns guide nerve-cell channel production
Researchers at the University of Pennsylvania School of Medicine have discovered that introns, or junk DNA to some, associated with RNA are an important molecular guide to making nerve-cell electrical channels.   view more (2008-02-06)

Age-related vision problems may be associated with cognitive impairment
Older patients with advanced age-related macular degeneration and reduced vision may be more likely to also have cognitive impairment, or problems with thinking, learning and memory.   view more (2006-04-11)

Stress significantly hastens progression of Alzheimer's disease
Stress hormones appear to rapidly exacerbate the formation of brain lesions that are the hallmarks of Alzheimer's disease, according to researchers at UC Irvine.   view more (2006-08-30)

International scientists tackle obstacles to treating brain disorders
A research team led by scientists at the University of Minnesota Medical School and Oregon Health & Science University have outlined the challenges and made suggestions on how to advance research and improve treatments for brain disorders.   view more (2007-12-21)

Nixing immaturity in red blood cells
A process of self-digestion called autophagy prompts the maturation of red blood cells. Without a protein called Nix, the cells would not effectively rid themselves of organelles called mitochondria and consequently become short-lived, leading to anemia, said researchers at Baylor College of... view more (2008-05-05)

Scientists ask whether microscaffolding can help stem cells rebuild brain after stroke damage
Inserting tiny scaffolding into the brain could dramatically reduce damage caused by strokes the UK National Stem Cell Network Annual Science Meeting will hear today (10 April).   view more (2008-04-10)

One hit of crystal meth causes birth defects: U of T study
A single prenatal dose of methamphetamine - commonly known as speed - may be enough to cause long-term neurodevelopmental problems in babies, say University of Toronto researchers.   view more (2005-07-27)

Unfolded proteins may protect cells from dying
When cells get stressed, their proteins go unfolded. It's a reaction with a straightforward name: the unfolded protein response. Now, new research from Rockefeller University shows that this phenomenon actually serves a protective role; rather than a sign that the cell has given up, it may be a... view more (2006-12-27)
