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.

Connection between eating meat and faster weaning process

Carnivory is behind the evolutionary success of humankind. When early humans started to eat meat and eventually hunt, their new, higher-quality diet meant that women could wean their children earlier. Women could then give birth to more children during their reproductive life, which is a possible contribution to the population gradually spreading over the world.

Breakdown of white-matter pathways affects decision-making as we age

If you are an aging baby boomer and you've noticed it's a bit harder to drive to unfamiliar locations or to pick a new brand of olive oil at the supermarket, you can blame it on the white matter in your brain.

Interferon beta-1a shows promise against MS

People who received injections of the multiple sclerosis (MS) drug interferon beta-1a soon after their first signs of possible MS were less likely to progress to clinically definite MS than people who switched to interferon beta-1a from placebo, according to new phase three results of the three-year REFLEXION clinical trial that will be presented as part of the Emerging Science program at the American Academy of Neurology's 64th Annual Meeting in New Orleans, April 21 to April 28, 2012.

Therapeutic hypothermia reduces in-hospital deaths among sudden cardiac arrest patients

Forced body cooling known as therapeutic hypothermia has reduced in-hospital deaths among sudden cardiac arrest patients nearly 12 percent between 2001 and 2009, according to a Mayo Clinic study being presented at the upcoming American Academy of Neurology 2012 Annual Meeting in New Orleans.

Researchers discover new stem cell in the adult brain

Researchers at Lund University in Sweden have discovered a new stem cell in the adult brain. These cells can proliferate and form several different cell types -- most importantly, they can form new brain cells. Scientists hope to take advantage of the finding to develop methods to heal and repair disease and injury in the brain.

UH to conduct research on causes and treatment of learning disabilities

The National Institutes of Health (NIH) has awarded a five-year, $9 million grant to the University of Houston's Texas Center for Learning Disabilities to conduct research on the causes and treatment of learning disabilities in children and adolescents. UH is one of four universities nationally to receive funding from the NIH for a learning disability research center.

Even a little physical activity a day keeps Alzheimer’s away

It is estimated that by 2030, the number of people with Alzheimer's disease worldwide is expected to double to 80 million. A new study shows a ray of hope. It found that daily physical activity might provide a person's best chances of staving off the degenerative brain disorder - even if they're over 80 years old.Additionally exercise does not have to be strenuous. Activities such as cooking and cleaning also led to a protective benefit.

Regenerative medicine research offers hope for the blind

The University College London researchers transplanted immature vision cells directly into the mouse retina. They noted that within weeks the cells began to integrate into the retina and the researchers, led by Prof Robin Ali in the university’s Institute of Ophthalmology, were able to show that vision began to return to the mice.

Physical exercise, meditation can change brains for the better

Practices like physical exercise, certain forms of psychological counseling and meditation can all change brains for the better, and these changes can be measured with the tools of modern neuroscience, according to a review article now online at Nature Neuroscience.

Perampanel drug may significantly reduce seizure frequency

A new type of anti-epilepsy medication that selectively targets proteins in the brain that control excitability may significantly reduce seizure frequency in people whose recurrent seizures have been resistant to even the latest medications, new Johns Hopkins-led research suggests.

New passive vaccine reverses dangerous symptoms of cocaine overdose

Scientists are reporting development and successful testing in laboratory mice of a substance that shows promise for becoming the first antidote for cocaine toxicity in humans. According to a report in ACS' journal Molecular Pharmaceutics, the new so-called "passive vaccine" reversed the motor impairment, seizures and other dangerous symptoms of a cocaine overdose, which claims thousands of lives each year among users of the illicit drug.

First specific antidote for cocaine toxicity

Scientists at The Scripps Research Institute have shown that an injectable solution can protect mice from an otherwise lethal overdose of cocaine. The findings could lead to human clinical trials of a treatment designed to reverse the effects of cocaine in case of emergency. Cocaine is involved in more than 400,000 emergency-room visits and about 5,000 overdose deaths each year in the United States.

UCSF scientists solve mystery of how selective hearing works

The longstanding mystery of how selective hearing works - how people can tune in to a single speaker while tuning out their crowded, noisy environs - is solved this week in the journal Nature by two scientists from the University of California, San Francisco.

First neurobiological model for third-party punishment

In a paper published online on April 15 by the journal Nature Neuroscience, a pair of neuroscientists from Vanderbilt and Harvard universities has proposed the first neurobiological model for third-party punishment. It outlines a collection of potential cognitive and brain processes that evolutionary pressures could have re-purposed to make this behavior possible.

Autologous BMMNCs reduce vascular growth in patients with diabetes

Autologous (self-donated) mononuclear cells derived from bone marrow (BMMNCs) have been found to significantly induce vascular growth when transplanted into patients with diabetes who are suffering from critical limb ischemia caused by peripheral artery disease (PAD), a complication of diabetes.

Test can reliably diagnose and monitor brain tumor without the need for surgery

In a breakthrough for the way brain cancer is diagnosed and monitored, a team of researchers, lead by Anna M. Krichevsky, PhD, of the Center of Neurologic Diseases at Brigham and Women's Hospital (BWH) in Boston and Santosh Kesari, MD, PhD, director of Neuro-Oncology at UC San Diego Moores Cancer Center, have demonstrated that brain tumors can be reliably diagnosed and monitored without surgery.
