A wider range of sounds for the deaf
06-08-2007 · EurekAlert!A tiny electrode array placed directly in the auditory nerve could overcome limitations of today's widely used cochlear implants, initial research in animals suggests. Such a device would allow deaf people to hear low-pitched sounds typical in speech, converse in a noisy room and enjoy a symphony.

- Wanting a bite of everything: Hungry people crave more variety
09-12-2007 · EurekAlert!
When we long for something intensely -- like a much-needed vacation -- a wider array of options will sound appealing, potentially leading to some out-of-character choices. Similarly, when we are especially hungry and presented with an range of menu choices, we are more likely to deviate from our favorite meal.

10-05-2007 · EurekAlert!
For the more than 50 million Americans who experience the phantom sounds of tinnitus -- ringing in the ears that can range from annoying to debilitating -- certain well-trained rats may be their best hope for finding relief.

- Nutrients might prevent hearing loss, new animal study suggests
03-28-2007 · EurekAlert!
In a new study in animals, University of Michigan researchers report that a combination of high doses of vitamins A, C, and E and magnesium, taken one hour before noise exposure and continued as a once-daily treatment for five days, was very effective at preventing permanent noise-induced hearing loss. The animals had prolonged exposure to sounds as loud as a jet engine at take-off at close range.

- Sight, sound processed together and earlier than previously thought
10-29-2007 · EurekAlert!
The area of the brain that processes sounds entering the ears also appears to process stimulus entering the eyes, providing a novel explanation for why many viewers believe that ventriloquists have thrown their voices to the mouths of their dummies.

- Lend me your ears -- and the world will sound very different
01-13-2008 · EurekAlert!
BBSRC scientists have found that the part of the brain that deals with sound, the auditory cortex, is adapted in each individual and tuned to the world around us. We learn throughout our lives how to localize and identify different sounds. It means that if you could hear the world through someone else's ears it would sound very different to what you are used to.

- Rutgers neuroscience may hold key to hearing loss remedy
12-18-2007 · EurekAlert!
A Rutgers University team is opening new doors to improved hearing for the congenitally or profoundly deaf. They researchers found that two neurotrophin proteins in the cochlea -- brain-derived neurotrophic factor and neurotrophin-3 -- figure prominently in the relay of sound messages to the brain. The research is showing precisely how these multidimensional proteins operate in the cochlea. Their findings could lead to a new generation of cochlear implants.

- Ears ringing? Johns Hopkins scientists ID the brain's own clarion
10-31-2007 · EurekAlert!
Brain scientists at Johns Hopkins have discovered how cells in the developing ear make their own noise, long before the ear is able to detect sound around them. The finding, reported in this week's Nature, helps to explain how the developing auditory system generates brain activity in the absence of sound. It also may explain why people sometimes experience tinnitus and hear sounds that seem to come from nowhere.

- New findings contradict a prevailing belief about the inner ear
02-12-2008 · EurekAlert!
A healthy ear emits soft sounds in response to the sounds that travel in. Detectable with sensitive microphones, these otoacoustic emissions help doctors test newborns' hearing. A deaf ear doesn't produce these echoes.

- Scientists model a cornucopia of Earth-sized planets
09-24-2007 · EurekAlert!
In the Star Wars movies fictional planets are covered with forests, oceans, deserts, and volcanoes. But new models from a team of MIT, NASA, and Carnegie scientists begin to describe an even wider range of Earth-size planets that astronomers might actually be able to find in the near future.
