UC Berkeley neuroscientists and UCSF surgeons recorded electrical activity in the temporal lobe -- the seat of the auditory system -- to discover how the brain encodes sound. Their model allows them to predict what a person heard based solely on temporal lobe activity. If, as studies suggest, internal "imagined" conversations activate similar areas of the temporal lobe, it may be possible to hear the internal verbalizations of people who cannot talk because of paralysis or stroke.

 | University of Utah scientists used invisible infrared light to make rat heart cells contract and toadfish inner-ear cells send signals to the brain. The discovery someday might improve cochlear implants for deafness and lead to devices to restore vision, maintain balance and treat movement disorders like Parkinson's. ...> Full Article |
Hearing loss can affect anyone, at any time. But it can be especially frightening for someone who suddenly starts to lose hearing during adulthood. Northwestern Memorial physicians are participating in an investigative study to help these individuals.

 | Scientists at the UK's National Physical Laboratory have developed a means of representing a 3-D model ear, to help redefine the standard for a pinna simulator (the pinna is the outer part of the ear) -- used to measure sound in the way we perceive it. ...> Full Article |
The UK's first operation to fit a single cochlear implant capable of giving sound in both ears takes place this Friday, thanks to the work of the South of England Cochlear Implant Centre, based at the University of Southampton.

The radar system incorporates a computer, two video cameras and a scanning light source to warn the blind of obstacles with audible alerts. The system detects obstacles -- even those overhead -- by scanning the depth of its surroundings, taken from two different angles -- similar to that of the human eye.

 | If a siren sounded but you were deaf, might you still be able to hear the sound? That is a challenge being addressed by doctors at the University of Cincinnati's Functional Neuroscience Center.The center was recently designed one of a select number of national Auditory Brainstem Centers by Cochlear Corporation, and will study an investigational device designed to help deaf patients regain the ability to process some types of noise. ...> Full Article |
Children with cochlear implants in both ears appear to have difficulty controlling the loudness and pitch of their voices, but these measures improve over time, according to a report in the January issue of Archives of Otolaryngology -- Head & Neck Surgery, one of the JAMA/Archives journals.
