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.

Caffeine prevents multiple sclerosis-like disease in mice

Mice given caffeine equivalent to a human drinking six to eight cups of coffee a day were protected from developing experimental autoimmune encephalomyelitis (EAE), the animal model for the human disease Multiple Sclerosis (MS), according to researchers at Cornell University.

Blood pressure enzyme can have tumor-sensing role

By increasing production of a blood pressure-regulating enzyme in mice, researchers have found they can enhance the mouse immune system's ability to sense tumor growth.

Leaky blood vessels open up nerve cells to toxic assault In Lou Gehrig's disease

Leaky blood vessels that lose their ability to protect the spinal cord from toxins may play a role in the development of amyotrophic lateral sclerosis, better known as ALS or Lou Gehrig's disease, according to research published in the April issue of Nature Neuroscience.

Transplanted dopamine neurons are affected by the Parkinson's disease process

A new groundbreaking study published in Nature Medicine has implications for the future of transplantation and stem cell therapies as a treatment for Parkinson's disease.

Significant dementia risk attributable to small blood vessel damage

Autopsy data of 221 men and women found that the brains of one-third of individuals who had dementia before death showed evidence of small, cumulative blood vessel damage that can arise from hypertension or diabetes.

Pediatricians alerted to the developmental nature of underage drinking in special journal supplement

In a special supplement to Pediatrics, edited and sponsored by the National Institute on Alcohol Abuse and Alcoholism (NIAAA), physicians will have access in one place to the reviews and analyses of current research on biological, behavioral, and environmental changes during childhood and adolescence that foster the initiation, maintenance, and acceleration of illegal use of alcohol by underage youth.

NYU dental professor discovers biological clock linking tooth growth to other metabolic processes

This clock, or biological rhythm, controls many metabolic functions and is based on the circadian rhythm, which is a roughly 24-hour cycle that is important in determining sleeping and feeding patterns, cell regeneration, and other biological processes in mammals.

Australian research tackles brain cancer, stroke

New studies at the University of Adelaide, Australia, will delve into some of the crucial issues surrounding death by brain tumours and stroke.

Mitochondria play role in pathogenesis of AD and estrogen-induced neuroprotection

As the major source of free radicals in cells, mitochondria contribute to the high levels of oxidative stress believed to play a role in the pathogenesis of Alzheimer's disease.

Fetal cells transplanted into the brain to treat Parkinson's may not function long term

Neurons grafted into the brain of a patient with Parkinson's disease fourteen years ago have developed Lewy body pathology, the defining pathology for the disease, according to research by Jeffrey H. Kordower, PhD, and associates and published in the April 6 issue of Nature Medicine.

Alzheimer's vaccine clears amyloid plaques but has little effect on learning and memory impairment

A promising vaccine being tested for Alzheimer's disease does what it is designed to do -- clear beta-amyloid plaques from the brain -- but it does not seem to help restore lost learning and memory abilities, according to a University of California, Irvine study.

1/3 of risk for dementia attributable to small vessel disease, autopsy study shows

Alzheimer's disease may be what most people fear as they grow older, but autopsy data from a long-range study of 3,400 men and women in the Seattle region found that the brains of a third of those who had become demented before death showed evidence of small vessel damage: the type of small, cumulative injury that can come from hypertension or diabetes.

Aripiprazole has potential for treating alcohol dependence

Aripiprazole is currently approved to treat bipolar disorder as well as schizophrenia. A new study has found that it significantly and dose-dependently increases the sedative effects of alcohol and, to a lesser degree, decreases the euphoric effects of alcohol. Future research will need to examine the beneficial versus the side effects of aripiprazole for treatment of alcohol dependence.
