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.

Paclitaxel may benefit Alzheimer's and Parkinson's movement disorders

Angiotech Pharmaceuticals have announced that a preclinical study published in today's early edition of the Proceedings of the National Academy of Sciences highlights the positive effects of Paxceed on movement disorders commonly seen in diseases known as taupathies, such as Alzheimer's and Parkinson's.

Ballet dancers’ brains reveal the art of imitation

Scientists have discovered that a system in our brain which responds to actions we are watching, such as a dancer’s delicate pirouette or a masterful martial arts move, reacts differently if we are also skilled at doing the move.

Santa can do the job and Christmas is saved!

Calculations maintain that the laws of physics should prevent Santa Claus from delivering all his gifts and that Santa would burn up in the atmosphere if he tried. The internet magazine, forskning.no, has put together a team of four top researchers to look into the case. The panel’s conclusion is clear: Santa can do the job and Christmas is saved!

May soon be possible to identify people at risk and even to treat a heart problem with a drug that works on the brain

Sudden cardiac death from emotional stress may be triggered by uneven signals from the brain to the heart, according to a study by University College London (UCL) scientists published in the January issue of Brain.

Turning off cell suicide switch fails to stop prion damage

Researchers knew that prions, the misfolded proteins that cause mad cow disease and other brain disorders, were killing off a class of important brain cells in a transgenic mouse model. But when they found a way to rescue those cells, they were astonished to discover the mice still became sick.

Teen concerns about inhalants and painkiller use

According to the Department of Health and Human Services, results from the annual Monitoring the Future (MTF) survey indicate an almost 7 percent decline of any illicit drug use in the past month by 8th, 10th, and 12th graders combined from 2003 to 2004.

Mutant gene that starves the brain of serotonin 10 times more prevalent in depressed patients

A mutant gene that starves the brain of serotonin, a mood-regulating chemical messenger, has been discovered and found to be 10 times more prevalent in depressed patients than in control subjects, report researchers funded by the National Institutes of Health’s National Institute of Mental Health (NIMH) and National Heart Lung and Blood Institute (NHLBI).

Vitamin E supplements may reduce the risk for death from amyotrophic lateral sclerosis (ALS)

Researchers from the Harvard School of Public Health and the American Cancer Society have found that regular use of vitamin E supplements may reduce the risk for death from amyotrophic lateral sclerosis (ALS) also known as Lou Gehrig’s Disease.

Cancer drug paclitaxel may reduce the adverse effects of Alzheimer's disease

In a preclinical efficacy trial, the cancer drug paclitaxel (Paxceed)–which exerts its effects by binding to and stabilizing microtubules inside cells–reduced the adverse effects of Alzheimer's disease (AD)-like pathology in a mouse model.

DLX5 gene may play a role in the pathology of Rett Syndrome

A research team led by Terumi Kohwi-Shigematsu of the Life Sciences Division of Lawrence Berkeley National Laboratory has identified a gene, DLX5, that may play a role in the pathology of Rett Syndrome, a devastating neurological disorder diagnosed almost exclusively in girls.

Stem cells use inflammatory signals to find injured tissue

A joint effort led by stem cell biologist Evan Y. Snyder, M.D., Ph.D., of The Burnham Institute, and Samia J. Khoury, M.D., of Harvard Medical School and Brigham and Women’s Hospital, report data suggesting that stem cells use inflammatory signals to “know” where they must home.

Polls show more teen girls see "alcopop" ads than women age 31-44

The American Medical Association (AMA) released the results of two nationwide polls today that reveal the extent of underage consumption and marketing exposure to "alcopops" or so-called "girlie drinks." The AMA expressed concern that hard-liquor brands are using these sweet-flavored malt beverages as "gateway" beverages to attract less-experienced drinkers.

Rett Syndrome, the first identified epigenetic disease - linked to specific defects in the three-dimensional folding of chromatin

Sometime between the age of 6 and 18 months, after a period of seemingly normal development, girls affected with Rett Syndrome lose interest in play; they gradually become withdrawn and anxious, develop autistic-like behaviors, and acquire specific symptoms like repetitive teeth-grinding and hand-wringing.

Ethical challenges ahead for neuroscience and society

Are we ready for a future where brain scans invade our private thoughts? Will we have to alter our brains chemically to keep competitive at our jobs? Could science determine that "souls" do not exist, and, if so, what does that mean for how we think of ourselves as human beings?

New clue to nerve growth may help regeneration efforts

Johns Hopkins scientists have discovered how one family of proteins repels growing nerves and keeps them properly on track during development.

How radiation therapy is used to safely and effectively treat various cancers

To help cancer patients and their families better understand their treatment options before making a decision, the American Society for Therapeutic Radiology and Oncology has published seven patient information brochures that explain how radiation therapy is used to safely and effectively treat various cancers.

Odor identification test, strong predictor of Alzheimer's Disease

The inability to identify the smell of lemons, lilac, leather and seven other odors predicts which patients with minimal to mild cognitive impairment (MMCI) will develop Alzheimer's Disease, according to a study presented today at the American College of Neuropsychopharmacology (ACNP) annual meeting.
