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.

Link between auditory working memory, musical aptitude and reading ability

Auditory working memory and attention, for example the ability to hear and then remember instructions while completing a task, are a necessary part of musical ability. But musical ability is also related to verbal memory and literacy in childhood. New research published in BioMed Central's open access journal Behavioral and Brain Functions shows how auditory working memory and musical aptitude are intrinsically related to reading ability, and provides a biological basis for this link.

Inhaled anesthetics do not increase incidence of postoperative delirium

A study presented at ANESTHESIOLOGY 2011 in Chicago this week offered firm evidence that commonly used inhaled anesthetics such as isoflurane do not increase the incidence of postoperative delirium, which can affect how well some patients recover after surgery.

African-American or Hispanic children less likely to receive CT scans after head trauma

White children are far more likely to receive cranial computed tomography (CT) scans in an emergency department following minor head trauma than are African-American or Hispanic children, a study by researchers at UC Davis has found.

Brain tumour discovery offers drug treatment hope

Australian scientists have played a key role in the identification of a new biochemical mechanism that allows brain tumours to survive and grow, offering hope of new drug treatments for some of the most aggressive tumours.

National award encourages bio-science student researchers

A key challenge for the bio-sciences sector is to keep its best research graduates in science and in Australia. The national student awards recognise and encourage promising research students and raise awareness of biosciences research translation and applications.

Johns Hopkins Brain Science Institute organizes Drug Discovery in Academia symposium

A symposium to be hosted by the Johns Hopkins Brain Science Institute (BSi) on Oct. 18 at the Baltimore Convention Center will bring together the pharmaceutical industry and academic-based research institutions with the common goal of exploring how the two can best work together to enhance and facilitate the discovery of new drugs.

Functional MRI examines brain activation in individuals with low and high LRs to alcohol

A low level of response (LR) to alcohol reflects at least in part a low brain response to alcohol and carries significant risk for the later development of alcoholism. This study used functional magnetic resonance imaging (fMRI) to examine brain activation in individuals with low and high LRs to alcohol while they performed a cognitive task.

Virtual brain models for epilepsy and schizophrenia

Virtual brains modeling epilepsy and schizophrenia display less complexity among functional connections, and other differences compared to healthy brain models, researchers at Case Western Reserve University School of Medicine report.

New book on pediatric stroke and cerebrovascular diseases

Two decades after the first edition, a third edition of the definitive textbook on stroke in children -- Pediatric Stroke and Cerebrovascular Disorders -- has been published by Demos Medical Publishing of New York City.

Emory researcher provides overview on 'CVD and PCOS' in APS conference

Sarah Berga, MD, former Chair of the Department of Gynecology and Obstetrics at the Emory University School of Medicine, is a researcher whose work focuses on understanding the impact of metabolic and psychological stresses on the reproductive system and as a cause of infertility, as well as on PCOS. She will provide an overview of her team's work in a presentation entitled, "CVD and PCOS." Her remarks are part of the Physiology of Cardiovascular Disease: Gender Disparities conference, October 12 at the University of Mississippi in Jackson.

Racial disparities in cranial CT scan use for children with minor head trauma

African-American and Hispanic children are less likely to receive a cranial computed tomography (CT) scan in an emergency department (ED) following minor head trauma than white children, according to an abstract presented Friday, Oct. 14 at the American Academy of Pediatrics (AAP) National Conference and Exhibition in Boston.

Brain scans can evaluate new treatments for attention deficit disorder

Scientists have developed a way to evaluate new treatments for some forms of attention deficit disorder. Working in mice, researchers at Washington University School of Medicine in St. Louis showed that they can use brain scans to quickly test whether drugs increase levels of a brain chemical known as dopamine.

Scientists reveal how resistance to hormone leptin develops

The effects of obesity - both on our bodies and on the health budget - are well known, and now, scientists are getting closer to understanding how the disease progresses, providing clues for future treatments.

Brain stem cell treatment for multiple sclerosis

The prospect of doing human clinical trials with stem cells to treat diseases like multiple sclerosis may be growing closer, say scientists at the University at Buffalo and the University at Rochester, who have developed a more precise way to isolate stem cells that will make myelin.

Penn researchers demonstrate sound-processing deficits in mice brains with mutated dysbindin gene

Recent studies have identified many genes that may put people with schizophrenia at risk for the disease. But, what links genetic differences to changes in altered brain activity in schizophrenia is not clear. Now, three labs at the Perelman School of Medicine at the University of Pennsylvania have come together using electrophysiological, anatomical, and immunohistochemical approaches - along with a unique high-speed imaging technique - to understand how schizophrenia works at the cellular level.

Scientists characterize and isolate potential stem cells to treat MS, myelin disorders

Scientists have improved upon their own previous world-best efforts to pluck out just the right stem cells to address the brain problem at the core of multiple sclerosis and a large number of rare, fatal children's diseases.

Different molecular mechanisms in suprachiasmatic nucleus linked to jet lag differences

It's no secret that long-distance, west-to-east air travel - Seattle to Paris, for example - can raise havoc with a person's sleep and waking patterns, and that the effects are substantially less pronounced when traveling in the opposite direction.

First physical evidence that bilingualism delays onset of Alzheimer's

Researchers at St. Michael's Hospital have found that people who speak more than one language have twice as much brain damage as unilingual people before they exhibit symptoms of Alzheimer's disease. It's the first physical evidence that bilingualism delays the onset of the disease.
