Schizophrenia could be caused by faulty signalling in the brain, according to new research published today in the journal Molecular Psychiatry. In the biggest study of its kind, scientists looking in detail at brain samples donated by people with the condition have identified 49 genes that work differently in the brains of schizophrenia patients compared to controls.

People voluntarily pick what information they store in short-term memory. Now, using functional magnetic resonance imaging (fMRI), researchers can see just what information people are holding in memory based only on patterns of activity in the brain.

People who received a mild electrical current to a motor control area of the brain were significantly better able to learn and perform a complex motor task than those in control groups. The findings could hold promise for enhancing rehabilitation for people with traumatic brain injury, stroke and other conditions.

When it comes to keeping brains alive, it seems nature has deemed that females are more valuable then males. As reported in this weeks' JBC, researchers found that nutrient deprivation of neurons produced sex-dependent effects.

A tug-of-war between the two sides of the brain causes it to become asymmetrical, according to research published today in the journal Neuron. Asymmetry in the brain is thought to be important to enable the two hemispheres to specialise and operate more efficiently.

A new area of the cerebral cortex has evolved to enable man and higher primates to pick up small objects and deftly use tools, according to neuroscientists at the University of Pittsburgh School of Medicine and Pittsburgh's Veterans Affairs Medical Center.

For the first time, scientists at Children's National Medical Center have successfully identified a key developmental program for the amygdala—the part of the limbic system that impacts how the brain creates emotional memories and responses.

We've all experienced the feeling of not knowing where we are. Being disoriented is not pleasant, and it can even be scary, but luckily for most of us, this sensation is temporary. The brain employs a number of tricks to reorient us, keeping our confusion to a minimum and quickly pointing us in the right direction.

New cells are born every day in the brain's hippocampus, but what controls this birth has remained a mystery.

Dollar signs for eyes – cartoonists have been drawing them for years, and the artists, while whimsical, may have been onto something. According to new research from UC San Diego, areas of the brain responsible for vision respond more strongly to objects of value.

Researchers at the University of Rochester have shown that the human brain—once thought to be a seriously flawed decision maker—is actually hard-wired to allow us to make the best decisions possible with the information we are given. The findings are published in today's issue of the journal Neuron.

New research by a Rice University psychologist clearly identifies the parts of the brain involved in the process of choosing appropriate words during speech.
