That's because a new study has found that women are better at finding and remembering words than men. Researchers from the University of Bergen in Norway have analysed the results of 168 studies on gender differences in'verbal fluency' and'verbal-episodic memory'. Verbal fluency is a measure of one's vocabulary, while verbal-episodic memory is the ability to recall words one has come across in the past. The female advantage is consistent across time and life span, but it is also relatively small,' said Professor Marco Hirnstein.

From the scans they were able to create a complete road map of the connections in each of their brains, called their'connectome'.

WASHINGTON – Scientists have trained rats to drive tiny cars in exchange for pieces of cereal, and found that learning the task lowered their stress levels. Their study not only demonstrates how sophisticated rat's brains are, but could one day help in developing new nonpharmaceutical forms of treatment for mental illness, said senior author Kelly Lambert of the University of Richmond in Virginia on Wednesday. Lambert said she had long been interested in neuroplasticity -- how the brain changes in response to experience and challenges -- and particularly wanted to explore how well rats that were housed in more natural settings ("enriched environments") performed against those kept in labs. She and colleagues modified a robot car kit by adding a clear plastic food container to form a driver compartment with an aluminum plate placed on the bottom. Copper wire was threaded horizontally across the cab to form three bars: left, center and right.

The test is still experimental, unavailable to the public outside of clinical trials. Its developers say it needs further study in many more women to determine whether the early findings hold up. If it does come to market, it will not be for several years, and its use might initially be limited to women at high risk. Dr. Emanuel F. Petricoin, who helped create the test, said, ''I'm all too aware as an F.D.A. scientist of promising early results that start to fail as you go into the real world.''
