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.

Genes that make bacteria make up their minds

Bacteria are single cell organisms with no nervous system or brain.

Sexual reversal in men and women with schizophrenia in terms of neuronal circuit

The brain of a schizophrenic woman possesses masculine qualities while that of a man with the same disease has feminine attributes, according to a recent study by Dr. Adrianna Mendrek from Fernand-Seguin Research Centre of Louis-H. Lafontaine Hospital.

New evidence supports use of catheter-based therapy to remove blood clots in stroke patients

Nearly 90 percent of the 700,000 strokes that affect U.S. patients each year are caused by a blockage of blood vessels supplying the brain, known as ischemic stroke.

Eating disorders should be recognized as serious mental illnesses

In the U.S. and abroad, the failure of insurers and other gatekeepers to treatment to consistently recognize eating disorders as serious mental illnesses has resulted in an ongoing heath care crisis for sufferers and their families.

Clarke clarifies pattern recognition theory

Recent commentary has suggested that the extent to which anomaly theories have become ingrained in the minds of academics and popular commentators alike has led to certain common assumptions and misconceptions about Clarke's pattern recognition theory of humour.

Twin nanoparticle shown effective at targeting, killing breast cancer cells

A team of investigators at Brown University has developed a novel way to treat a class of breast cancer cells. The team has created twin nanoparticles that specifically targets the Her-2 tumor cell and unload a cancer-fighting drug directly into it. The result is a boost in antitumor activity while minimizing side effects. The findings of this study have been published in the Journal of the American Chemical Society.

Fructose metabolism by the brain increases food intake and obesity

The journal Biochemical and Biophysical Research Communications (BBRC), published by Elsevier, will publish an important review this week online, by M. Daniel Lane and colleagues at Johns Hopkins, building on the suggested link between the consumption of fructose and increased food intake, which may contribute to a high incidence of obesity and Type 2 diabetes.

Rockefeller neuroscientist applies basic science to health care reform

A self-described "molecular sociologist" is extending his basic research to the national policy debate on health care reform. Bruce McEwen, head of the Laboratory of Neuroendocrinology, led a panel of scientific experts last month at the Institute of Medicine's Summit on Integrative Medicine and the Health of the Public. The Institute is the most prominent independent medical advisory board in the country and will release a report from the conference in November, as Congress is likely to be considering major health care legislation.

Non-invasive brain scanning technique may trace development of Parkinson's disease

While finding a biomarker for Parkinson's disease that would let physicians screen for or track its progression remains an elusive goal, a team led by a University of Illinois at Chicago neuroscientist has shown that a non-invasive brain scanning technique offers promise.
