Researchers discover mechanism that determines when detailed memories are retained
The levels of a chemical released by the brain determine how detailed a memory will later be, according to researchers at UC Irvine. view more (2006-10-16)
Bound by Attention: Bringing rats and humans together
When picking through a basket of fruit, it doesn't seem very difficult to recognize a green pear from a green apple. This is easy, thanks to "feature binding"- a process by which our brain combines all of the specific features of an object and gives us a complete and unified picture of it. view more (2008-11-19)
Single genetic defect produces specific cognitive deficit in mice
Researchers have found that, in mice, producing a single genetic defect in a molecule that "reloads" neurons to trigger one another using the neurotransmitter acetylcholine impairs the mice's ability to recognize objects or other mice. view more (2006-09-07)
Barrow researchers identify new brain receptor, possible target for Alzheimer's treatment
Barrow Neurological Institute researchers have identified a novel receptor in the brain that is extremely sensitive to beta-amyloid peptide (AB) and may play a key role in early stages of Alzheimer's disease. view more (2009-07-17)
Caltech researchers find tiny genetic change keeps nicotine from binding to muscle cells
A tiny genetic mutation is the key to understanding why nicotine--which binds to brain receptors with such addictive potency--is virtually powerless in muscle cells that are studded with the same type of receptor. view more (2009-03-24)
Research study describes the role part of the brain plays in memory
A research with experimental rats carried out by the Institute of Neuroscience of the UAB describes the brain region connected to how our declarative memory functions. view more (2007-07-18)
Artificial membranes can reveal biological weapons
Today there is a great need for portable equipment that can quickly detect chemical and biological weapons such as nerve gases, viruses, bacteria, and toxins. In a new dissertation the Swedish researcher Inga Gustafsson shows that artificial membranes can be used for this purpose in future biosensors. Biosensors have already... view more... (2004-01-16)
Defects in crucial brain protein implicated in memory loss
The ability to recognize familiar objects and companions is lost when levels of a protein crucial for recycling a chemical messenger in the brain are reduced, mimicking some of the symptoms of Alzheimer's disease. view more (2006-09-07)
Neurotransmitters in biopolymers stimulate nerve regeneration
Research reported December 11 in the journal Advanced Materials describes a potentially promising strategy for encouraging the regeneration of damaged central nervous system cells known as neurons. view more (2007-12-12)
Moderate Alcohol Consumption Could Reduce Risk Of Dementia (p 281)
A Dutch study in this week's issue of THE LANCET suggests that light-to-moderate alcohol consumption could reduce the risk of dementia among older people, regardless of the type of alcoholic drink consumed. Light-to-moderate alcohol consumption reduces the risk of coronary heart disease and stroke. Because vascular disease is associated with... view more... (2002-01-23)
Nicotine exposure during development leads to hearing problems
Scientists know that children of women who smoke during pregnancy can develop hearing-related cognitive deficits. For the first time, researchers believe they have evidence that not only implicates nicotine as the culprit, but also shows what the substance does to the brain to cause these deficits. view more (2006-07-19)
Researchers 'see' structure of open nicotinic acetylcholine ion channels
The neurotransmitter acetylcholine is an essential chemical communicator, carrying impulses from neurons to skeletal muscle cells and many parts of the nervous system. view more (2008-04-08)
Caltech scientists engineer supersensitive receptor, gain better understanding of dopamine system
Genetically modifying a receptor found on the neurons that produce the neurotransmitter dopamine has given California Institute of Technology (Caltech) researchers a unique glimpse into the workings of the brain's dopamine system--as well as a new target for treating diseases that result from either too much or too little of this critical... view more...

Cholinesterase inhibitors reduce aggression, wandering and paranoia in Alzheimer's disease
Cholinesterase inhibitors, used to treat cognitive symptoms of Alzheimer's disease, are also a safe and effective alternative therapy for the behavioral and psychological symptoms of dementia, according to a study that appears in the December 2008 edition of Clinical Interventions in Aging. view more (2008-12-10)
Nicotine may have more profound impact than previously thought
Nicotine isn't just addictive. It may also interfere with dozens of cellular interactions in the body, new Brown University research suggests. view more (2009-04-06)
Dual treatment of incontinence and dementia associated with functional decline
Older nursing home residents who took medications for dementia and incontinence at the same time had a 50 percent faster decline in function than those who were being treated only for dementia, according to a study from researchers at Wake Forest University School of Medicine and colleagues. view more (2008-05-01)
Mechanism of nicotine's learning effects explored
While nicotine is highly addictive, researchers have also shown the drug to enhance learning and memory—a property that has launched efforts to develop nicotine-like drugs to treat cognitive deficits in Alzheimer's and Parkinson's diseases, schizophrenia, and attention-deficit/hyperactivity disorder. view more (2007-04-05)
Dissecting the machinery of nicotine's reward
Understanding what makes people crave the high of nicotine is a key to developing treatment for this highly addictive drug. And that understanding involves tracing the neural machinery by which nicotine switches on the brain's reward machinery. view more (2006-06-15)
Do 'light' cigarettes deliver less nicotine to the brain than regular cigarettes?
For decades now, cigarette makers have marketed so-called light cigarettes - which contain less nicotine than regular smokes - with the implication that they are less harmful to smokers' health. A new UCLA study shows, however, that they deliver nearly as much nicotine to the brain. view more (2008-09-29)
Promising new treatment for Alzheimer's suggested based on Hebrew University research
Research carried out at the Hebrew University of Jerusalem has resulted in a promising approach to help treat Alzheimer's disease in a significant proportion of the population that suffers from a particularly rapid development of this disease. view more (2009-07-21)
