Alex Martin placed rats in a partially echo-free, sound-proof chamber and simultaneously played two types of sounds: Gaussian sound (containing all frequencies) of 25 decibels and a pure sound (made up of one frequency). He found that auditory neurons respond

Corporate culture is, above all, the most important factor in driving innovation. Firm level factors are more important than anything else -- even location -- in predicting radical innovation.

A new study confirms that exercise can reverse the age-related decline in the production of neural stem cells in the hippocampus of the mouse brain, and suggests that this happens because exercise restores a brain chemical which promotes the production

Students are creating idealized versions of themselves on social networking websites -- Facebook and MySpace are the most popular -- and using these sites to explore their emerging identities, psychologists report. Parents often understand very little about this phenomenon, they
