  Deaf - Wikipedia, the free encyclopedia
Depending on the definition of deafness used, the global deaf population is estimated to be roughly 0.1% of the total population (1 in 1000).
Deaf is also used as a colloquialism to refer to a recalcitrant individual or someone unwilling to listen, obey or acknowledge an authority or partner.

 Encyclopedia: Models of deafness
Deafness, or the state of being deaf, is most commonly defined as the inability of the unaided ear to perceive sounds.
The cultural model of deafness arises from, but is not limited to, deaf people themselves, especially pre-lingually deaf people whose primary language is the sign language of their nation or community; their children, families, friends and other members of their social networks.
Deaf cultural values find abhorrent the dismantling of the residential schools since they were considered the best possible environment, the highest quality of life, in which to acquire and enrich sign language fluency and pass on deaf cultural values that serve as tools and solutions to challenges in a predominantly hearing world.

 Models of deafness and the implications for families of deaf children
For children deaf from birth, deafness is seen as a medical condition as the deafness is usually diagnosed within a medical context, often in hospital, and the first action will be to consider whether a cure is possible.
The Deaf community has a long tradition of storytelling in sign language and more recently the creation of poetry in BSL, the nature of the language demanding that it is performed and not read as it has to be seen in action to be appreciated.
The model of deafness has implications for a family's decisions about the language or languages to use with the very young child, and for the choice of approach to education.

One mouse model for human nonsyndromic deafness is the deafness (dn) mouse, a spontaneous mutation in the curly-tail (ct) stock.
Mouse models for human deafness have not only proven instrumental in the identification of genes for hereditary hearing loss, but are excellent model systems in which to examine gene function as well as the resulting pathophysiology.

And Mueller and his laboratory are looking to find more of these components by developing models of deafness, looking for important proteins, and setting up in vitro and in vivo systems to test the effects of those proteins on mechanosensory pathways.
Many of the models of deafness have been around for years, and some of them have names like jerker, waltzer, and shaker, which reflect phenotypes arising from inner ear defects and balance problems.
Positional cloning traditionally entails the use of classical genetic mapping methods to confine the location of the gene to a particular area in the genome, extensive sequencing of the region in question, and the performance of computer-aided searches through databases to find homology between sequences in that region and known genes.

The Deaf child, like their hearing counterpart, is born with an innate ability to acquire language as part of their development.
Both deaf and hearing children have similiar capacity for language and with access to the appropriate models they go through the same stages in the acquisition of language.
When deafness is diagnosed (usually when the child is 9 months old), a visiting teacher goes to the child's home to help the child learn to speak.

African deaf groups seeking roots and cultural identity need not, of course, begin with distant history -- there are arguments for starting with materials near to hand, such as membership lists in their own archives or some inspirational current biographies, or school rolls [25].

 The Molecular and Biological Basis of Genetic Deafness   (Site not responding. Last check: 2007-11-05)
We use the mouse as a model system because it is only possible to carry out the detailed studies of development and electrophysiological measures of function that are necessary to understand the process of hearing impairment if we use an animal model.
For example, when we identify a new gene involved in deafness in the mouse, we collaborate with human geneticists to look for mutations in equivalent genes in human families with deafness.
The mutant genes are identified by positional cloning, gene expression patterns are analysed, cochlear function is assessed by electrophysiological measurement, gross structural development of the labyrinth is studied by clearing and paint-filling combined with 3D reconstruction of serial sections, and the ultrastructural development of the inner ear is investigated by transmission and scanning electron microscopy.

About 10 percent of children who are born deaf have a form of Usher syndrome, and it is the major cause of deaf–blindness.
According to the National Institute on Deafness and Other Communication Disorders, which is one of the National Institutes of Health, more than half of the estimated 16,000 deaf-blind people in the United States are believed to have Usher syndrome.
In Usher syndrome and other "sensory neuronal" diseases that cause deafness, the hair cells in the cochlea are unable to maintain the symmetric arrays of what are known as "stereocilia." Somehow the genetic defects cause the stereocilia to splay and degenerate instead of making bundles.

Since 1992, the Summer Program has provided the Deaf and Hard-of-Hearing students enrolled in the Marie H. Katzenbach School for the Deaf, ages three to 10, a Summer Program as an extension of their academic year in an environment that offers direct communication with staff and peers.
Since Deafness is a low incident disability and many of our Deaf children are isolated in their neighborhoods, unable to communicate with their neighborhood-hearing peers during the summer months, the Summer Program provides an opportunity for our children to maintain their academic and communication skills in an environment where communication is free and natural.
For our Lower School children, who find themselves separated from their Deaf peers when school is not in session, it provides opportunities to socialize and maintain their language skills.
