Functional plasticity of language-related brain areas after cochlear implantation.
Using PET, the cerebral network engaged by heard language processing in normal hearing subjects was compared with that in patients who received a cochlear implant after a period of profound deafness. The experimental conditions were words, syllables and environmental sounds, each controlled by a noise baseline. Four categories of effect were observed: (i) regions that were recruited by patients...
متن کاملCross-modal plasticity preserves functional specialization in posterior parietal cortex.
In congenitally blind individuals, many regions of the brain that are typically heavily involved in visual processing are recruited for a variety of nonvisual sensory and cognitive tasks (Rauschecker 1995; Pascual-Leone et al. 2005). This phenomenon-cross-modal plasticity-has been widely documented, but the principles that determine where and how cross-modal changes occur remain poorly understo...
متن کاملExtensible Grammars for Language Specialization
A frequent dilemma in the design of a database programming language is the choice between a language with a rich set of tailored notations for schema definitions, query expressions, etc., and a small, simple core language. We address this dilemma by proposing extensible grammars, a syntax-definition formalism for incremental language extensions and restrictions based on an initial core language...
متن کاملHemispheric specialization for sign language.
Most studies on sign lateralization provide inconclusive results about the role of the two hemispheres in sign language processing, whereas the cases reported in the clinical literature show sign language impairment only following left hemisphere damage, suggesting a similar neural organization to spoken languages. By discriminating different levels of processing, a tachistoscopic study found t...
متن کاملVisualization of Spoken Language for Deaf People
The academic achievement of the deaf is related to the difficulty in communication, not to the cognitive abilities. Without communication, their needs are generally misinterpreted and ignored. Accumulated years of misunderstanding will impair their academic as well as social success. Since the hearing world uses spoken language to communicate, the deaf are commonly isolated because they can use...
