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.

Novel compound treats addiction by eliminating drug-associated memories

Addicts, even those who have been abstinent for long periods of time, are often still vulnerable to their own memories of prior drug use.

MicroRNA may link smoking risk gene to neurobiology of addiction

During the past several years, significant progress has been made in identifying susceptibility genes for nicotine dependence through genetic linkage and association analyses.

Discovery of ion channel turns ear on its head

Scientists thought they had a good model to explain how the inner ear translates vibrations in the air into sounds heard by the brain.

New drug restricts the growth of neuroblastoma

Researchers from the Children's Cancer Hospital at The University of Texas M. D. Anderson Cancer Center have found a new drug that restricts the growth of neuroblastoma, a childhood brain cancer.

Research finds gene bringing together animal and human research in alcoholism

An important genetic study conducted through Mayo Clinic has identified vital new information concerning alcoholism in subjects with European ancestry, according to a recent issue of Alcohol: Clinical and Experimental Research.

Calming neurological effects of nicotine studied

The calming neurological effects of nicotine have been demonstrated in a group of non-smokers during anger provocation.

Even modest exercise improves insulin sensitivity, decreases fat in the liver and inflammation in belly fat

A new University of Illinois study suggests that moderate amounts of exercise alone can reduce the inflammation in visceral fat - belly fat, if you will - that has been linked with metabolic syndrome, a group of risk factors that predict heart disease and Type 2 diabetes.

DTI allows radiologists to see areas of the brain rarely seen using other imaging modalities

Radiologists are now able to look at parts of the brain using diffusion tensor imaging (DTI) that are rarely visible with any other imaging method, according to a study performed at Beth Israel Deaconess Medical Center in Boston, MA.

Natural plant cannabinoids reduce multi-drug resistant infections

Cannabis Science, Inc., Dr. Robert Melamede, PhD., Director and Chief Science Officer, reported to the Board on the current state of research into the use of natural plant cannabinoids to reduce the spread of drug-resistant bacteria, including methicillin-resistant Staphyloccus aureus (MRSA), and the prospects for development of topical whole-cannabis treatments.

Researchers discover that gene switches on during development of epilepsy

A discovery made by researchers at Wake Forest University School of Medicine while studying mice may help explain how some people without a genetic predisposition to epilepsy can develop the disorder.

Hard evidence for SIDS babies

By analysing the brain tissue of babies suspected of having died of SIDS, Dr Rita Machaalani and Dr Karen Waters from the Faculty of Medicine and the University's Bosch Institute have shown that cigarette smoke induces abnormalities in babies' brains, putting them at greater risk.

Mitochondrial peptide Humanin linked to neuronal cell survival and regulation of glucose metabolism

Recent studies have shown that the mitochondrial peptide Humanin (HN) protects against neuronal cell death such as happens in Alzheimer's disease.

FDA gives 'go ahead' for phase II clinical trials of Bryostatin for the treatment of Alzheimer's disease

The Food and Drug Administration (FDA) has given the Blanchette Rockefeller Neurosciences Institute (BRNI) the go-ahead to conduct Phase II clinical trials of Bryostatin for the treatment of Alzheimer's disease patients.

Genetics may help explain alcohol-related susceptibility and resistance

Drinking alcohol during pregnancy can lead to teratogenesis, the development of embryonic defects.

Binge drinking may be detrimental to the developing adolescent brain

A study of adolescent binge drinkers has found that even relatively infrequent exposure to large amounts of alcohol during the teen years may compromise the integrity of the brain's white matter, which is critical for the efficient relay of information within the brain.

Researchers study why people who are obese become hypertensive

When Francois Abboud began his work at the University of Iowa in 1960, little was known about the constant physiological chatter between the brain and the blood vessels.

Children resuscitated at birth at risk for lower IQs

Children who were resuscitated at birth have increased risk of low intelligence quotient (IQ) at age eight years, even if they were apparently healthy in the 28 days (neonatal period) following birth.

A nanoscale motor in the ear

Utah and Texas researchers have learned how quiet sounds are magnified by bundles of tiny, hair-like tubes atop "hair cells" in the ear: when the tubes dance back and forth, they act as "flexoelectric motors" that amplify sound mechanically.

Scientists suggest a mechanism for how lithium works in bipolar treatment

Lithium has been established for more than 50 years as one of the most effective treatments for bipolar mood disorder.

Discovery of agents that speed up destruction of amyloid beta proteins

Taking a new approach to the treatment and prevention of Alzheimer's disease, a research team led by investigators at the Mayo Clinic campus in Florida has shown that druglike compounds can speed up destruction of the amyloid beta (A-beta) proteins that form plaque in the brains of patients with the disorder.
