The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Possible new treatment strategy for Alzheimer's disease

A new study in mice identifies one of the missing steps in how Alzheimer's develops and suggests a possible new treatment strategy, according to researchers at Columbia University Medical Center and Weill Cornell Medical College and their colleagues.

Computer technology helps to make sense of human brain

Through the HBP, federal agencies fund a system of web-based databases and research tools that help brain scientists share and integrate their raw, primary research data. At the conference, eminent neuroscientists and neuroinformatics specialists will recap the field's achievements and forecast its future technological, scientific and social challenges and opportunities.

Scientists discover gene for Parkinson's disease

UCL scientists have discovered a new gene implicated in the early development of Parkinson's disease. In a study of families with early onset disease, Professor Nick Wood and colleagues at University College London's Institute of Neurology identified a novel gene which produces a malfunctioning protein that could pave the way for new treatments for Parkinson sufferers.

Sound sleep in infants lessens likelihood of drug abuse in later years

A long-term study has found a significant connection between sleep problems in children’s toddler years and the chance that they’ll use alcohol, cigarettes, and drugs early in their teen years. Young teens whose preschool sleep habits were poor were more than twice as likely to use drugs, tobacco, or alcohol.

Muscle stem cells morph to resemble nerve cells

Taking a major step forward in stem cell biology, researchers at The University of Texas M. D. Anderson Cancer Center have turned muscle progenitor cells — stem cells that are “committed” to becoming muscle tissue — into cells that look and act like neurons (nerve cells).

Extra funding aids brain research

A healthy arrival of funds over the past couple of years has produced "endorphins" in McMaster’s "brain" that has psychology researchers very excited.

Alzheimer fact sheet released

Dementia is a syndrome consisting of a number of symptoms that include loss of memory, judgment and reasoning, and changes in mood, behaviour and communication abilities. Alzheimer Disease, the most common form of dementia, accounts for 64 per cent of all dementias in Canada.

Autism gene discovered

Researchers at Mount Sinai School of Medicine are first to strongly link a specific gene with autism. While earlier studies have found rare genetic mutations in single families, a study published in the April issue of the American Journal of Psychiatry is the first to identify a gene that increases susceptibility to autism in a broad population.

The Howard Hughes Medical Institute commits $30 million to beat infectious diseases

The Howard Hughes Medical Institute (HHMI) is stepping up its commitment to fostering international biomedical research with two new competitions for more than $30 million in research grants to biomedical scientists outside the United States. Both competitions are aimed at promising researchers whose careers are still developing and who are the most likely targets of enticing job offers in more economically privileged countries.

Researchers examine community-based drinkers rather than abstinent alcoholics

Almost all knowledge about brain damage due to chronic alcohol consumption has been gathered from alcoholics, who have generally been studied toward the end of their institutionalized treatment program (several weeks after their last drink) or many months into abstinence.

Drug's ability to reverse acute ischemic stroke

Ischemic stroke patients who arrive at the hospital too late to receive currently available treatment options might someday have a new treatment option. Northwestern Memorial Hospital is the only site in Chicago to participate in a phase III trial of abciximab (ReoPro - Centocor/Eli Lilly and Company), which seeks to determine the drug's ability to improve neurological function and minimize disability in patients who present with an acute ischemic stroke.

Both sides of brain working together are key to math giftedness

There really may be something different about the brains of math-heads. Mathematically gifted teens did better than average-ability teens and college students on tests that required the two halves of the brain to cooperate, as reported in the April issue of Neuropsychology, published by the American Psychological Association (APA).

Australian symposium on stroke and head injury

A condition which leaves some stroke and head injury victims unable to see half their world will be the subject of a one-day symposium being hosted by Southern Cross University (SCU) this week.

Low carb diets should be avoided by growing children and adolescents

Even if you're not eating "low-carb," it's a good bet you at least know several people who are. Many people have found this the way to lose and maintain weight, while others argue that although you may see results, it could ultimately cause health problems such as heart disease. Most pediatricians would agree that a low-carb diet is not one a growing child should embrace.

A drug that improves function of retinal blood vessels may be able to reduce the risk of stroke

The small study found that endothelial function is abnormal in eye blood vessels of patients who have early-stage hypertension, but that treatment with an angiotensin-receptor blocker (ARB) drug improves endothelial function. The endothelium is the lining of vessel walls and plays a key role in the vessels’ ability to relax and to constrict.

Alcohol screening can spot addiction

Have you ever felt like you needed a drink? If an occasional cocktail changes into a need, it could mean an alcohol problem. National Alcohol Screening Day is April 8. In cities and towns throughout the United States, screening programs will be offered to help people determine whether they exhibit drinking behaviors that could be signs of alcohol addiction.

Results of Creutzfeldt-Jakob disease research in people who received human growth hormone from cadavers

The largest study of its kind, designed to track the development of Creutzfeldt-Jakob disease in people who received human growth hormone from cadavers, has found that the vast majority of those who received the hormone did not contract the fatal condition. However, some recipients (26 out of approximately 7,700) did develop the disease.

A protein involved in the release of neurotransmitters in the brain is essential to learning and memory

A study published today in Neuron offers the first evidence that lack of this protein - known as RIM1 alpha - causes profound deficits in the learning process. The discovery is a major step in understanding the molecular events that underlie learning and memory - complex processes that can be impaired in human neuropsychiatric disorders such as Alzheimer's disease, mental retardation and schizophrenia.

New research findings in study of Rett Syndrome

Rudolf Jaenisch of the Whitehead Institute of Biomedical Research in Cambridge, MA reports in the April 6, 2004 online issue of the Proceedings of the National Academy of Sciences that introduction of the MeCP2 protein into post-mitotic nerve cells of MeCP2 mutant mice rescues the symptoms of Rett Syndrome. This raises the possibility that neurons are functionally normal in a newborn child and that neural dysfunction manifests itself only later due to prolonged MeCP2 deficiency. If correct, therapeutic strategies aimed at preventing the onset of Rett symptoms could be initiated at birth.

Effects of lead in petrol are well-known however a recent additive to petrol manganese may be just as toxic

The disastrous environmental and health effects of lead in petrol are well-known, and western countries have been phasing it out for many years now. However, a recent additive to petrol - manganese - may be just as toxic. A Macquarie University study aims to find out.
