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.

Media coverage of autism differs dramatically

Sifting through the pages of newspapers, most people reading stories about autism would think scientists are primarily grappling with understanding how environmental factors, such as childhood vaccines, might contribute to the condition.

One in four normal births cause brain hemorrhages in babies

Researchers in the United States have found that many babies who were delivered vaginally, experience bleeding in and around the brain shortly after birth.

Magnetic resonance angiography of supraaortic arteries

A novel type of contrast-enhanced magnetic resonance (MR) angiography is highly accurate in identifying blockages in the arteries that carry blood to the brain, according to a study in the February issue of Radiology.

Giving birth to a child naturally increases risk of hemorrhage in newborns

The first researchers to use magnetic resonance imaging (MRI) to study the brains of a large group of babies soon after birth found a small amount of bleeding in and around the brains of one in four babies who were delivered vaginally.

Stroke treatment helps victims recover brain function

A small but significant study in the U.S. has found that a treatment which was designed to clear blocked carotid arteries and prevent stroke has also improved brain function.

Multiple sclerosis far more common than previously thought

A new review of hundreds of research articles has shown that the prevalence of multiple sclerosis (MS) is far higher than previously thought amongst the U.S. population.

Scientists tackle huntingtin protein

McMaster scientists are very close to defining small molecule drugs that should be able to redirect the huntingtin protein from accumulating in the wrong place within brain cells, which could potentially translate to a therapy for Huntington's Disease (HD).

Gene produces springy protein keeping nerve cells flexible

If you bend a knee or an elbow, the nerves in your limbs stretch but do not break. A University of Utah study suggests why: A gene produces a springy protein that keeps nerve cells flexible. When the gene was disabled in tiny nematode worms, their nerve cells literally broke.

Nicotine addiction depends on a healthy insula

Smokers with a damaged insula - a region in the brain linked to emotion and feelings - quit smoking easily and immediately, according to a study in the Jan. 26 issue of the journal Science.

SH2B1 protein plays a key role in controlling body weight, response to insulin and leptin

A single protein in brain cells may act as a linchpin in the body's weight-regulating system, playing a key role in the flurry of signals that govern fat storage, sugar use, energy balance and weight, University of Michigan Medical School researchers report.

Molecular mechanism behind aggregation of amyloid beta peptide due to anesthetics

Inhaled anesthetics commonly used in surgery are more likely to cause the aggregation of Alzheimer's disease-related plaques in the brain than intravenous anesthetics say University of Pittsburgh School of Medicine researchers in a journal article published in Biochemistry.

Study sheds light on complex design of tears

It's no secret why we shed tears. But exactly what our tears are made of has remained a mystery to scientists.

New prognostic instrument improves prediction of stroke risk after TIA

The existing prognostic scores for early-risk stroke prediction after transient ischaemic attack (TIA have been validated and refined to develop a unified score that is more predictive than previous methods, according to an Article published in this week's issue of The Lancet.

Manipulation of proliferation and differentiation of human bone marrow derived neural stem cells in vitro and in vivo

Stem cells taken from adult human bone marrow have been manipulated by scientists at the Maxine Dunitz Neurosurgical Institute at Cedars-Sinai Medical Center to generate aggregates of cells called spheres that are similar to those derived from neural stem cells of the brain.

Melanin concentrating hormone found to be involved with insulin production

A new Joslin Diabetes Center-led study has shown conclusively that a neuropeptide, melanin concentrating hormone (MCH), found in the brain and known for its role in increasing appetite in people, plays a role in the growth of insulin-producing beta cells and the secretion of insulin.

Are you really what you eat?

Aston University in Birmingham, UK has launched a unique new laboratory facility dedicated to solving the mysteries that lie in the relationship between the food we eat and the human brain.

An active mind delays the onset of Alzheimer's

Learning appears to slow the development of two brain lesions that are the hallmarks of Alzheimer's disease, scientists at UC Irvine have discovered. The finding suggests that the elderly, by keeping their minds active, can help delay the onset of this degenerative disease.
