OBJECTIVE To investigate central auditory processing in children with unilateral stroke and to verify whether the hemisphere affected by the lesion influenced auditory competence. METHOD 23 children (13 male) between 7 and 16 years old were evaluated through speech-in-noise tests (auditory closure); dichotic digit test and staggered spondaic word test (selective attention); pitch pattern and ...

Neurons at higher stages of sensory processing can partially compensate for a sudden drop in peripheral input through a homeostatic plasticity process that increases the gain on weak afferent inputs. Even after a profound unilateral auditory neuropathy where >95% of afferent synapses between auditory nerve fibers and inner hair cells have been eliminated with ouabain, central gain can restore c...

BACKGROUND central auditory processing and exposure to metallic mercury. AIM to evaluate the performance on tests of central auditory processing in adolescents exposed to metallic mercury. METHOD participants were 52 adolescents, of both genders, who presented hearing thresholds within normal limits. The study group (SG) was composed by 21 adolescents who worked on the burning of gold-mercu...

Concepts in cognitive neuroscience fundamental to intervention are summarized. The functional plasticity of the maturing central nervous system offers opportunity to improve auditory processing skills. A comprehensive approach to improve listening comprehension and learning in children and youth with central auditory processing disorders is outlined. The management approach emphasizes developme...

Deficits in central auditory processing may occur in a variety of clinical conditions including traumatic brain injury, neurodegenerative disease, auditory neuropathy/dyssynchrony syndrome, neurological disorders associated with aging, and aphasia. Deficits in central auditory processing of a more subtle nature have also been studied extensively in neurodevelopmental disorders in children with ...

Audio-visual reaction time is a reliable indicator to assess the processing capability of central nervous system and sensory motor performance in response to an external stimulus. The present study was aimed to find out whether chronic smoking affects the processing capability of central nervous system. The audiovisual reaction times of 120 male subjects with age ranging from 25 to 55 years for...

Development of normal speech and language functions is closely related to normal hearing. However, most children with delayed or disturbed speech development show normal tone thresholds and here the investigation has to include higher levels in the auditory system. There is evidence for a connection between language impairment and a central auditory processing disorder, but the underlying mecha...
