St. Jude finds clues to hearing loss from chemotherapy

...ed more than 1,800 mice from 285 families using an auditory brainstem responses test. This test determines whether a particular mouse can respond to high frequencies by recording electrical activity from the hearing nerve and other parts of the brain in response to brief, high-frequency sounds. The team ident...

Humpback whales have brain cells also found in humans

... whales and dolphins, have demonstrated remarkable auditory and communicative abilities, as well as complex social behaviors. A new study published online November 27, 2006 in The Anatomical Record, the official journal of the American Association of Anatomists,compared a humpback whale brain with brains from...

Critical hearing gene helps send auditory messages to brain

Mirrors in the mind: New studies elucidate how the brain reflects onto itself the actions of others

...r neurons might contribute to our understanding of auditory cues. Past work had shown that in monkeys, so-called auditory mirror neurons activate when monkeys perform certain actions and when they hear the same actions bei...

Slow brain waves play key role in coordinating complex activity

...In this way, the researchers argue, areas like the auditory cortex and frontal cortex, separated by several inches in the cerebral cortex, can coordinate activity. "If you are reading something, language areas oscillate in theta frequency allowing high-gamma-related neural activity in individual neurons to t...

New dyslexia theory blames 'noise'

...ce, was the lead author on a study of dyslexia and auditory noise published this year in Proceedings of the National Academy of Sciences. Ziegler said his results suggest that dyslexia stems from shaky categories for phonemes (the basic sounds of language). "In silence, information is often redundant ...

The researchers found that volunteers?sense of timing was impaired when the interval was randomly preceded by a "distracter" tone. "Our results suggest that the timing mechanisms that underlie our abi...

Stem cell transplants explored at Stanford as a possible treatment for hearing loss

...n Disorders, lauded Heller as "one of the leading auditory neuroscientists" and points to his stem cell regeneration research as a high priority for the institute. Heller's vision is to develop a variety of possible cures for deafness. For the past year and a half, since coming to Stanford from Harvard...
