To elude bats, a moth keeps its hearing in tune

...een reported for insects, or in fact for any other hearing system in the animal kingdom. This finding changes our understanding of the co-evolution of bats and moths—for example, as the moth cleverly tunes its ear to enhance its detection of bats, do some bats in turn modify their calls to avoid detection by...

Stanford discovery may help predict when toxoplasma can be deadly

...their fetuses, potentially resulting in sight and hearing problems as well as learning disabilities. The new findings have implications for determining how to treat these and other infected people: More aggressive therapy may be warranted if a strain that contains the proteins that increase virulence is...

Slow brain waves play key role in coordinating complex activity

...list of words, the slow, theta oscillations in the hearing area of the brain become coupled with the fast, high-gamma oscillations in the same area. When two different brain areas then oscillate together at the same theta frequency and phase, it becomes much easier for these regions to tune in the high-gamma...
