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.

Portable device to check for concussions

Moderate alcohol consumption enhances the formation of new nerve cells

Moderate alcohol consumption over a relatively long period of time can enhance the formation of new nerve cells in the adult brain. The new cells could prove important in the development of alcohol dependency and other long-term effects of alcohol on the brain. The findings are published by Karolinska Institutet.

Guidelines for research involving human embryonic stem cells

The National Academies today recommended guidelines for research involving human embryonic stem cells, and urged all institutions conducting such research to establish oversight committees to ensure that the new guidelines will be followed.

Search for new multiple sclerosis drug

UT Southwestern Medical Center is the lead research site testing a new treatment for a rare form of multiple sclerosis. Called "primary progressive," this type of MS affects about 15 percent of patients with the neurodegenerative disease.

Physical activity appears to inhibit Alzheimer's

Physical activity appears to inhibit Alzheimer's-like brain changes in mice, slowing the development of a key feature of the disease, according to a new study.

Use of positron emission tomography may eliminate more strenuous drug development trials with animals

A number of articles explore the use of positron emission tomography (PET) and small animal imaging—nonsurgical techniques that open the door to understanding and treating human diseases—in the April issue of the Society of Nuclear Medicine’s Journal of Nuclear Medicine.

Bypass surgery does not carry long term neurological effects

In a wide retrospective review of the effects of coronary artery bypass grafting (CABG) on memory and other brain functions a team of U.S. researchers has concluded that, while there may be transient short-term effects, the procedure itself probably does not cause late or permanent neurological effects.

Antibody for West Nile virus shows promise

Researchers have developed an antibody that can cure mice of West Nile virus (WNV) infection, a disease for which no specific treatment exists, the National Institute of Allergy and Infectious Diseases (NIAID) has announced.

Gene therapy for Alzheimer's disease shows promise

In the first clinical trial of gene therapy for Alzheimer's disease researchers have produced preliminary evidence that gene therapy may slow the decline in mental functioning associated with Alzheimer's disease.

New drug combo helps prevent strokes

A British research team at St. George's Hospital Medical School in London, have found that the addition of the anti-clotting drug Plavix to daily doses of aspirin helps prevent the risk of later strokes better than using aspirin alone.

Substantially more effective therapy than current treatments for Alzheimer's disease

PET scans and cognitive tests have suggested that Alzheimer's disease patients with genetically modified tissue inserted directly into their brains show a reduction in the rate of cognitive decline and increased metabolic activity in the brain, according to a study published in the April 24, 2005 online issue of the journal Nature Medicine by researchers at the University of California, San Diego (UCSD) School of Medicine.

Increased risk associated with combining carotid artery, coronary artery surgeries

Among patients undergoing evaluation for coronary artery bypass surgery, stroke neurologists are frequently consulted when the patient also has severe carotid artery stenosis (blockage of an artery that supplies blood to the brain).

Important new finding about the brain and its stem cells

A family's bravery and generosity in the face of their son's death three years ago has enabled researchers to make an important new finding about the brain and its stem cells.

Evidence suggests bypass surgery free of long-term brain effects

A broad retrospective review of the effects of coronary artery bypass grafting (CABG) on memory and other brain functions concludes that, while there may be transient short-term effects, the procedure itself probably does not cause late or permanent neurological effects.

Testing new manic depression drugs in slime mould

Research by University College London (UCL) scientists could lead to the development of more effective drugs for treating manic depression thanks to a new screening approach developed in a "slime mould" - a microbe that lives in leaves and dung on forest floors.

Study shows older children can benefit from treatment of eye disorder

For decades, vision specialists believed that a condition called amblyopia, or "lazy eye," must be treated before a child turns 7 to be successful. But a new study, involving Vanderbilt Children's Hospital researchers, finds it's not too late for older children.

Scientists have, for the first time, induced a state of reversible metabolic hibernation in mice

Scientists at Fred Hutchinson Cancer Research Center have, for the first time, induced a state of reversible metabolic hibernation in mice. This achievement, the first demonstration of "hibernation on demand" in a mammal, ultimately could lead to new ways to treat cancer and prevent injury and death from insufficient blood supply to organs and tissues.

Nanoparticles reveal tiny cancerous tumors

Specially designed nanoparticles can reveal tiny cancerous tumors that are invisible by ordinary means of detection, according to a study by researchers at Washington University School of Medicine in St. Louis.

Rare surgery performed to remove pancreas, prevent diabetes and ease pain of chronic pancreatitis

In a 12-hour, dual-stage surgery known to be performed at only two other centers in the U.S., doctors at the University of Alabama at Birmingham (UAB) on Tuesday returned a patient's own insulin-producing cells to him after surgically removing his pancreas to eliminate constant, severe pain from chronic pancreatitis.
