A good ear: Rats identify specific sounds in noisy environments
A study conducted on hundreds of rats could help us understand how the brain identifies specific sounds in a noisy environment. view more (2008-11-19)
Lend me your ears -- and the world will sound very different
Recognising people, objects or animals by the sound they make is an important survival skill and something most of us take for granted. But very similar objects can physically make very dissimilar sounds and we are able to pick up subtle clues about the identity and source of the sound. view more (2008-01-14)
Sound adds speed to visual perception
The traditional view of individual brain areas involved in perception of different sensory stimuli-i.e., one brain region involved in hearing and another involved in seeing-has been thrown into doubt in recent years. view more (2008-08-12)
Neurons use chemical 'chords' to shape signaling
Researchers have discovered that neurons can use two different neurotransmitters that target the same receptor on a receiving neuron to shape the transmission of a nerve impulse. view more (2008-02-28)
Estrogen Controls How the Brain Processes Sound
Scientists at the University of Rochester have discovered that the hormone estrogen plays a pivotal role in how the brain processes sounds. view more (2009-05-06)
Auditory neurons in humans far more sensitive to fine sound frequencies than most mammals
The human ear is exquisitely tuned to discern different sound frequencies, whether such tones are high or low, near or far. But the ability of our ears pales in comparison to the remarkable knack of single neurons in the brain to distinguish between the very subtlest of sound frequencies. view more (2008-01-11)
Memory impairment associated with sound processing disorder
Mild memory impairment may be associated with central auditory processing dysfunction, or difficulty hearing in complex situations with competing noise, such as hearing a single conversation amid several other conversations, according to a report in the July issue of Archives of Otolaryngology-Head & Neck Surgery, one of the JAMA/Archives... view more...

Selective attention increases both gain and feature selectivity of the human auditory cortex
On Sept. 19, a research report by Helsinki University of Technology, Laboratory of Computational Engineering scientists will appear in the online, open-access journal PLoS ONE, showing that selective attention increases both gain and feature selectivity of the human auditory cortex. view more (2007-09-19)
How the brain sorts babble into auditory streams
Known as "the cocktail party problem," the ability of the brain's auditory processing centers to sort a babble of different sounds, like cocktail party chatter, into identifiable individual voices has long been a mystery. view more (2005-10-06)
Brain center for 'sound space' identified
While the visual regions of the brain have been intensively mapped, many important regions for auditory processing remain terra incognita. Now, researchers have identified the region responsible for a key auditory process-perceiving "sound space," the location of sounds. view more (2007-09-20)
A Neural Mosaic of Tones
The brain filters what we hear. It can do this in part because particular groups of neurons react to specific frequencies of sound. view more (2006-06-23)
The Human Brain: Detective of auditory and visual change
The human brain is capable of detecting the slightest visual and auditory changes. Whether it is the flash of a student's hand into the air or the faintest miscue of a flutist, the brain instantaneously and effortlessly perceives changes in our environment. view more (2008-01-21)
Iron deficiency in womb may delay brain maturation in preemies
Iron plays a large role in brain development in the womb, and new University of Rochester Medical Center research shows an iron deficiency may delay the development of auditory nervous system in preemies. view more (2009-05-05)
Brain's 'hearing center' may reorganize after implant of cochlear device
Cochlear implants-electronic devices inserted surgically in the ear to allow deaf people to hear-may restore normal auditory pathways in the brain even after many years of deafness. view more (2007-07-24)
Neural mechanism reveals why dyslexic brain has trouble distinguishing speech from noise
New research reveals that children with developmental dyslexia have a deficit in a brain mechanism involved in the perception of speech in a noisy environment. view more (2009-11-12)
Excitation pattern peak is more important determinant of vowel quality
The perceptions of five Chinese vowel /u, o, a, y, i/ and many perceptional phenomena can be explained well by the excitation pattern peaks. The study is reported in Science in China, Series F-Information Sciences, Volume 52，Issues 10 (Oct, 2009). view more (2009-11-06)
Age-related difficulty recognizing words predicted by brain differences
Older adults may have difficulty understanding speech because of age-related changes in brain tissue, according to new research in the May 13 issue of The Journal of Neuroscience. view more (2009-05-13)
Wired for sound: How the brain senses visual illusions
In a study that could help reveal how illusions are produced in the brain's visual cortex, researchers at the UCSD School of Medicine have found new evidence of rapid integration of auditory and visual sensations in the brain. view more (2007-04-12)
Larvae shun the light
Drosophila larvae avoid light during the foraging stage of their development. Research published in the open access journal BMC Neuroscience shows that both 5-HT (serotonergic) and corazonergic neurons have a role in regulating this behavior. view more (2009-06-23)
Sensitivity of brain center for 'sound space' defined
While the visual regions of the brain have been intensively mapped, many important regions for auditory processing remain "uncharted territory." Now, researchers at the Hebrew University of Jerusalem and elsewhere have identified a region responsible for a key auditory process - perceiving "sound space," the location of sounds,... view more...
