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.

New method for targeting malignant brain tumors

A new method for targeting malignant brain tumors through inducing the cancerous cells to "commit suicide" has been developed by a team of researchers headed by a Hebrew University of Jerusalem professor of biochemistry.

Evolutionary connection between food supply and brain size

In a study of orangutans living on the Indonesian islands of Borneo and Sumatra, scientists from Duke University and the University of Zurich have found what they say is the first demonstration in primates of an evolutionary connection between available food supplies and brain size.

Period 2 gene - key component of the circadian time-keeping system

By investigating how animals can predict the timing of food availability, researchers have identified the first gene critical for anticipation of mealtime. This gene, called Period 2, is a key component of the circadian time-keeping system.

New imaging technique reveals differences in brains of people with autism

Using a new form of brain imaging known as diffusion tensor imaging (DTI), researchers in the Center for Cognitive Brain Imaging at Carnegie Mellon University have discovered that the so-called white matter in the brains of people with autism has lower structural integrity than in the brains of normal individuals.

16 year old cancer victim dies after overdoses of radiation

A 16 year old cancer victim who was inadvertently given more than 17 overdoses of radiation during treatment for a brain tumour, has died at home nine months later.

Otoferlin, defective in a human deafness form, is essential for exocytosis at the auditory ribbon synapse

By studying a gene earlier linked to deafness in humans, researchers now have new insight into the molecular process by which components of the inner ear send messages to the brain.

Scientists discover how brain turns on system designed to protect nerve cells from toxic "free radicals"

Scientists at Dana-Farber Cancer Institute report they have found how the brain turns on a system designed to protect its nerve cells from toxic "free radicals," a waste product of cell metabolism that has been implicated in some degenerative brain diseases, heart attacks, strokes, cancer, and aging.

PGC-1 alpha implicated in Huntington's disease neurodegeneration

A metabolic disorder underlies the brain effects found in those with Huntington's disease, researchers report in an advance article publishing online October 19, 2006. The article will appear in the November 2006 issue of the journal Cell Metabolism, published by Cell Press.

Important first step towards designing new therapies for shingles

A team of scientists at the National Institute of Allergy and Infectious Diseases (NIAID), one of the National Institutes of Health (NIH), has identified a human protein that helps varicella-zoster virus, the cause of chickenpox and shingles, spread from cell to cell within the body.

Comprehensive review backs health benefits of eating fish

There is ample research advocating the nutritional benefits of eating fish and shellfish because fish is high in protein and omega-3 fatty acids.

Do the risks of eating fish outweigh the benefits? Yes or No

Fish is high in protein and omega-3 fatty acids. But concerns have been raised in recent years about chemicals found in fish from environmental pollution, including mercury, PCBs and dioxins. That has led to confusion among the public--do the risks of eating fish outweigh the benefits?

Parkinson's disease affects more than just motor control

Although Parkinson's disease is most commonly viewed as a "movement disorder," scientists have found that the disease also causes widespread abnormalities in touch and vision - effects that have now been verified using functional magnetic resonance imaging (fMRI) of the brain.

Researchers find areas in the brain that indicate bilingualism

The finding sheds new light on decades of debate about how the human brain's language centers may actually be enhanced when faced with two or more languages as opposed to only one.

Scans reveal differences in autistic brains

Researchers at the University of Washington's Autism Center have found new evidence that some regions in the brains of people with the developmental disorder autism may not communicate with each other as efficiently as they do in other people.

Cocaine addicts have an altered perception of reward

People addicted to cocaine have an impaired ability to perceive rewards and exercise control due to disruptions in the brain's reward and control circuits, according to a series of brain-mapping studies and neuropsychological tests conducted at the U.S. Department of Energy's Brookhaven National Laboratory.
