PET imaging of cochlear-implant and normal-hearing subjects listening to speech and nonspeech. (1/786)Functional neuroimaging with positron emission tomography (PET) was used to compare the brain activation patterns of normal-hearing (NH) with postlingually deaf, cochlear-implant (CI) subjects listening to speech and nonspeech signals. The speech stimuli were derived from test batteries for assessing speech-perception performance of hearing-impaired subjects with different sensory aids. Subjects were scanned while passively listening to monaural (right ear) stimuli in five conditions: Silent Baseline, Word, Sentence, Time-reversed Sentence, and Multitalker Babble. Both groups showed bilateral activation in superior and middle temporal gyri to speech and backward speech. However, group differences were observed in the Sentence compared to Silence condition. CI subjects showed more activated foci in right temporal regions, where lateralized mechanisms for prosodic (pitch) processing have been well established; NH subjects showed a focus in the left inferior frontal gyrus (Brodmann's area 47), where semantic processing has been implicated. Multitalker Babble activated auditory temporal regions in the CI group only. Whereas NH listeners probably habituated to this multitalker babble, the CI listeners may be using a perceptual strategy that emphasizes 'coarse' coding to perceive this stimulus globally as speechlike. The group differences provide the first neuroimaging evidence suggesting that postlingually deaf CI and NH subjects may engage differing perceptual processing strategies under certain speech conditions.

Recruitment of the auditory cortex in congenitally deaf cats by long-term cochlear electrostimulation. (2/786)In congenitally deaf cats, the central auditory system is deprived of acoustic input because of degeneration of the organ of Corti before the onset of hearing. Primary auditory afferents survive and can be stimulated electrically. By means of an intracochlear implant and an accompanying sound processor, congenitally deaf kittens were exposed to sounds and conditioned to respond to tones. After months of exposure to meaningful stimuli, the cortical activity in chronically implanted cats produced field potentials of higher amplitudes, expanded in area, developed long latency responses indicative of intracortical information processing, and showed more synaptic efficacy than in naive, unstimulated deaf cats. The activity established by auditory experience resembles activity in hearing animals. (+info)
Positron emission tomography in cochlear implant and auditory brain stem implant recipients. (3/786)OBJECTIVE: The purpose of this study was to determine whether similar cortical regions are activated by speech signals in profoundly deaf patients who have received a multichannel cochlear implant (CI) or auditory brain stem implant (ABI) as in normal-hearing subjects. STUDY DESIGN: Positron emission tomography (PET) studies were performed using a variety of discrete stimulus conditions. Images obtained were superimposed on standard anatomic magnetic resonance imaging (MRI) for the CI subjects. The PET images were superimposed on the ABI subject's own MRI. SETTING: Academic, tertiary referral center. PATIENTS: Five subjects who have received a multichannel CI and one who had received an ABI. INTERVENTION: Multichannel CI and ABI. MAIN OUTCOME MEASURE: PET images. RESULTS: Similar cortical regions are activated by speech stimuli in subjects who have received an auditory prosthesis. CONCLUSIONS: Neuroimaging provides a new approach to the study of speech processing in CI and ABI subjects. (+info)
Noninvasive direct stimulation of the cochlear nerve for functional MR imaging of the auditory cortex. (4/786)We herein present our preliminary experience with functional MR imaging of the direct electrical stimulation of the cochlear nerve using an MR imaging-compatible electrode placed in the external auditory meatus of five patients with binaural sensorineural hearing loss.

In three of five patients, it was possible to activate the superior temporal gyrus during functional MR imaging. No side effects were observed. (+info)
Cognitive factors and cochlear implants: some thoughts on perception, learning, and memory in speech perception. (5/786)Over the past few years, there has been increased interest in studying some of the cognitive factors that affect speech perception performance of cochlear implant patients. In this paper, I provide a brief theoretical overview of the fundamental assumptions of the information-processing approach to cognition and discuss the role of perception, learning, and memory in speech perception and spoken language processing. The information-processing framework provides researchers and clinicians with a new way to understand the time-course of perceptual and cognitive development and the relations between perception and production of spoken language. Directions for future research using this approach are discussed including the study of individual differences, predicting success with a cochlear implant from a set of cognitive measures of performance and developing new intervention strategies.

Electrical cochlear stimulation in the deaf cat: comparisons between psychophysical and central auditory neuronal thresholds. (6/786)Cochlear prostheses for electrical stimulation of the auditory nerve ("electrical hearing") can provide auditory capacity for profoundly deaf adults and children, including in many cases a restored ability to perceive speech without visual cues. A fundamental challenge in auditory neuroscience is to understand the neural and perceptual mechanisms that make rehabilitation of hearing possible in these deaf humans. We have developed a feline behavioral model that allows us to study behavioral and physiological variables in the same deaf animals. Cats deafened by injection of ototoxic antibiotics were implanted with either a monopolar round window electrode or a multichannel scala tympani electrode array. To evaluate the effects of perceptually significant electrical stimulation of the auditory nerve on the central auditory system, an animal was trained to avoid a mild electrocutaneous shock when biphasic current pulses (0.2 ms/phase) were delivered to its implanted cochlea. Psychophysical detection thresholds and electrical auditory brain stem response (EABR) thresholds were estimated in each cat. At the conclusion of behavioral testing, acute physiological experiments were conducted, and threshold responses were recorded for single neurons and multineuronal clusters in the central nucleus of the inferior colliculus (ICC) and the primary auditory cortex (A1). Behavioral and neurophysiological thresholds were evaluated with reference to cochlear histopathology in the same deaf cats. The results of the present study include: 1) in the cats implanted with a scala tympani electrode array, the lowest ICC and A1 neural thresholds were virtually identical to the behavioral thresholds for intracochlear bipolar stimulation; 2) behavioral thresholds were lower than ICC and A1 neural thresholds in each of the cats implanted with a monopolar round window electrode; 3) EABR thresholds were higher than behavioral thresholds in all of the cats (mean difference = 6.5 dB); and 4) the cumulative number of action potentials for a sample of ICC neurons increased monotonically as a function of the amplitude and the number of stimulating biphasic pulses. This physiological result suggests that the output from the ICC may be integrated spatially across neurons and temporally integrated across pulses when the auditory nerve array is stimulated with a train of biphasic current pulses. Because behavioral thresholds were lower and reaction times were faster at a pulse rate of 30 pps compared with a pulse rate of 2 pps, spatial-temporal integration in the central auditory system was presumably reflected in psychophysical performance.

Differential recruitment of the speech processing system in healthy subjects and rehabilitated cochlear implant patients. (7/786)Differences in cerebral activation between control subjects and post-lingually deaf rehabilitated cochlear implant patients were identified with PET under various speech conditions of different linguistic complexity. Despite almost similar performance in patients and controls, different brain activation patterns were elicited. In patients, an attentional network including prefrontal and parietal modality-aspecific attentional regions and subcortical auditory regions was over-activated irrespective of the nature of the speech stimuli and during expectancy of speech stimuli. A left temporoparietal semantic region was responsive to meaningless stimuli (vowels). In response to meaningful stimuli (words, sentences, story), left middle and inferior temporal semantic regions and posterior superior temporal phonological regions were under-activated in patients, whereas anterior superior temporal phonological regions were over-activated. These differences in the recruitment of the speech comprehension system reflect the alternative neural strategies that permit speech comprehension after cochlear implantation. (+info)
Responses of inferior colliculus neurons to amplitude-modulated intracochlear electrical pulses in deaf cats. (8/786)Current cochlear prostheses use amplitude-modulated pulse trains to encode acoustic signals. In this study we examined the responses of inferior colliculus (IC) neurons to sinusoidal amplitude-modulated pulses and compared the maximum unmodulated pulse rate (Fmax) to which they responded with the maximum modulation frequency (maxFm) that they followed. Consistent with previous results, responses to unmodulated pulses were all low-pass functions of pulse rate. Mean Fmax to unmodulated pulses was 104 pulses per second (pps) and modal Fmax was 60 pps. Above Fmax IC neurons ceased responding except for an onset burst at the beginning of the stimulus. However, IC neurons responded to much higher pulse rates when these pulses were amplitude modulated; 74% were relatively insensitive to carrier rate and responded to all modulated carriers including those exceeding 600 pps. In contrast, the responses of these neurons (70%) were low-pass functions of modulation frequency, and the remaining (30%) had band-pass functions with a maxFm of 42 and 34 Hz, respectively. Thus temporal resolution of IC neurons for modulated frequencies is significantly lower than that for unmodulated pulses. These two measures of temporal resolution (Fmax and maxFm) were uncorrelated (r(2) = 0.101). Several parameters influenced the amplitude and temporal structure of modulation responses including modulation depth, overall intensity and modulation-to-carrier rate ratio. We observed distortions in unit responses to amplitude-modulated signals when this ratio was 1/4 to 1/6. Since most current cochlear implant speech processors permit ratios that are significantly greater than this, severe distortion and signal degradation may occur frequently in these devices. (+info)
Cochlear implant technology is growing rapidly in Malaysia to assist patients with hearing problems especially among children. Cochlear implants may be beneficial for the speech development of children and help children attend normal schools. However, the success of cochlear implants depends on the detection and early intervention of children and efforts to habilitation / rehabilitation by therapists and parents.. The latest scenario in Malaysia, most users only use cochlear implant in one ear only. Therefore, various studies have been conducted to evaluate the benefits of cochlear implants. According to a study on the use of cochlear implant and its impact on the binaural processing for pediatric patients and adults showed that patients using bimodal fitting get better benefits than patients using cochlear implant or hearing aid in one ear only (Molly Justus, 2008).. ...
OBJECTIVE: To conduct a pilot study in adults with the Nucleus CI24M/SP5 cochlear implant system. PATIENTS AND METHODS: Eight postlingually deafened adults who had received little or no benefit from conventional hearing aids, equipped with the Nucleus CI24M/SP5 cochlear implant system. RESULTS AND CONCLUSIONS: The results indicate that most of the subjects were able to perform well in speech recognition tests. The test performances appeared to be strongly affected by the duration of deafness. The speech processors four user-selectable program memories have been extremely useful for the subjects to evaluate variations to the speech coding strategies in ordinary surroundings outside of the laboratory. The telemetry functions of the new implant provide a set of useful clinical and research tools for gathering greater insights into the in-situ operation of the implant. ...
TY - JOUR. T1 - Loudness balance between acoustic and electric stimulation by a patient with a multichannel cochlear implant. AU - Dorman, Michael. AU - Smith, L.. AU - Parkin, J. L.. PY - 1993/8. Y1 - 1993/8. N2 - Estimates of loudness balance were obtained for acoustically and electrically presented 250 Hz sine signals from a patient who uses the Ineraid multichannel cochlear implant. Acoustic and electric loudness matching was possible because the patient evidenced a 25 dB HL threshold at 250 Hz in his nonimplanted ear. The level of the electrical stimulus in microamperes required for a balance of loudness grew linearly with equal increments in decibels for the acoustic stimulus. These data, in concert with the very limited data from previous studies, provide a rationale for using a logarithmic transformation of acoustic to electric intensity in signal processors for cochlear implants.. AB - Estimates of loudness balance were obtained for acoustically and electrically presented 250 Hz sine ...
Children with profound deafness are at risk for serious reading difficulties. Multiple factors affect their development of reading skills, including use of cochlear implants. Further, multiple factors influence the overall success that children experience with their cochlear implants. These factors include the age at which they receive an implant, method of communication, vocabulary skills, preoperative residual hearing, and socioeconomic status. Ninety-one children with prelingual and profound hearing impairments who received cochlear implants at varying ages participated in the study. Structural equation modeling confirmed that multiple factors affected young cochlear implant users reading comprehension skills and that there were significant associations between the predictors of reading comprehension. Pre-implant vocabulary had an indirect positive effect on reading through postimplant vocabulary, which had a direct positive effect on reading. Overall, children with stronger language skills ...
OBJECTIVES: Monopolar stimulation of the most apical electrode produces the lowest pitch sensation in cochlear implants clinically. A phantom electrode that uses out-of-phase electrical stimulation between the most apical and the neighboring basal electrode can produce a lower pitch sensation than that associated with the most apical electrode. However, because of the absence of contacts beyond the apical tip of the array, the ability to assess the spread of electrical excitation associated with phantom stimulation is limited in the typical cochlear implant subject with no residual hearing. In the present study, the spread of electrical excitation associated with monopolar and phantom stimulation of the most apical electrode was assessed using electrical masking of acoustic thresholds in cochlear implant subjects with residual, low-frequency, acoustic hearing. DESIGN: Eight subjects with an Advanced Bionics cochlear implant and residual hearing in the implanted ear participated in this study ...

Cochlear implant and hearing loss videos including educational videos, cochlear implant testimonials and cochlear implant product videos
by Susan Boswell These are often the first words spoken when a cochlear implant recipients processor is turned on. And they have been a rite of passage for more than 36,000 people around the world who have received cochlear implants over the last two decades. Technological advances have brought dramatic changes in candidacy criteria, opening the door for more people with severe and profound hearing losses to choose this option.. When the U.S. Food and Drug Administration (FDA) first approved a cochlear implant with a single electrode for adults in 1985 and for children in 1990, only those who were almost completely deaf and could only perceive vibrations with a hearing aid could qualify.. Today, children and adults who were not candidates just two years ago may well be considered as candidates. The age of pediatric candidates has dropped from 2 years to as young as 12 months, and eligibility criteria for adults continue to expand.. A growing body of research has demonstrated that children who ...

Cochlear implants were created for adults and children that suffer from a form of hearing loss known as sensorineural hearing loss. In sensorineural hearing loss there is usually damage to the tiny hair like cells in the cochlea. The cochlea is the tiny snail shaped coil in your inner ear that transmits sound signals to the auditory nerve. When the tiny hair like cells in your cochlea are damaged they are unable to transmit the sound signals to the auditory nerve. The cochlear implant circumvents the cochleas tiny hair like cells and directly stimulates the auditory nerve.. So how does the cochlear implant work? First a tiny receiver is implanted just under your skin behind the ear. This receiver is then connected to tiny electrodes that have been placed in the cochlea. You are then fitted with an external auditory speech processor, a transmitter and a battery pack. The microphone looks like a hearing aid and is worn behind the ear or it can be worn somewhere else on your body depending on your ...

This encouraging book considers the implications for performance in light of the whole ...
A cochlear implant is an electronic device that transmits electrical impulses to the brain where they are perceived as sounds both for children who are born deaf or become deaf and also deaf or severely hard of hearing adults.. The cochlear implant consists of two parts:. - the external part with a speech processor incorporating a microphone which is placed behind the ear with a transmitter coil or with a compact, single-unit audio processor that is held in place by magnets over the implanted receiver. - a surgically implanted internal part consisting of a receiver package implanted in a recess in the mastoid bone which is connected to the electrode array positioned within the cochlea.. Today the possibility of obtaining a cochlear implant in Europe is still very uneven and depends in particular on the social insurance system of the country concerned.. It should be remembered that health policy in the European Union is in the first place the responsibility of each state member.. Numerous ...
Purpose: The purpose of this study was to examine the rate of progress in the 2nd implanted ear as it relates to the 1st implanted ear and to bilateral performance in adult sequential cochlear implant recipients. In addition, this study aimed to identify factors that contribute to patient outcomes. Method: The authors performed a prospective longitudinal study in 21 adults who received bilateral sequential cochlear implants. Testing occurred at 6 intervals: prebilateral through 12 months postbilateral implantation. Measures evaluated speech recognition in quiet and noise, localization, and perceived benefit. Results: Second ear performance was similar to 1st ear performance by 6 months postbilateral implantation. Bilateral performance was generally superior to either ear alone; however, participants with shorter 2nd ear length of deafness (|20 years) had more rapid early improvement and better overall outcomes than those with longer 2nd ear length of deafness (|30 years).

My attitudes and perspectives about young deaf children getting cochlear implants have gradually evolved since the first time I heard about deaf people getting cochlear implants. Growing up with deaf parents and attending deaf schools, I have a strong sense of pride of being deaf and being part of the Deaf community. I do not look at myself as disabled. I often say if I were given a choice to hear or stay deaf, I d choose to stay deaf. It is who I am. My family, my friends, and my community have taught me that being deaf is part of our culture and is a way of life. Many deaf people have succeeded in life without having the ability to hear. They ve become lawyers, doctors, scientists, and teachers. It has nothing to do with the ability to hear. It has to do with many other factors such as the person s attitude, values, beliefs, and motivation.. I used to oppose strongly the idea of deaf people getting cochlear implants. It indicates the need to fix the problem. I felt betrayed and angry that ...
The George Washington University Hospital offers cochlear implants for patients with hearing loss.

Objectives/Hypothesis: This study documents the importance of preserving residual low-frequency acoustic hearing as those with more residual hearing are selected for cochlear implantation. Surgical strategies used for hearing preservation with a short hybrid cochlear implant are outlined. The benefits of preserved residual low-frequency hearing, improved word understanding in noise, and music appreciation are described.. Study Design: Multicenter, prospective, single-subject design.. Methods: Records were reviewed of 21 individuals participating in an Food and Drug Administration (FDA) feasibility clinical trial who have received an Iowa/Nucleus 10 mm electrode. A second group of subjects receiving implants at the University of Iowa that have used the 10 mm device between 2 years and 6 months were also reviewed. Outcome measures included standardized tests of monosyllabic word understanding, spondees in noise, and common melody recognition.. Results: Low-frequency hearing was maintained in all ...
CRITIQUE: The number of children who receive cochlear implants is increasing, likely the result of many factors such as universal newborn hearing screening, improvements in audiological testing, and advances in hearing technology. Additionally, there has been a trend to provide cochlear implants to children at much younger ages than in the past. This book is an appropriate resource for students enrolled in college training programs and is also appropriate for school professionals who are new to the field of cochlear implants as well as those that have been working with implants for several years. The book addresses the issue that the procedures used to educate children with hearing losses have changed significantly over recent years. As the authors indicate, this book does not answer all questions regarding educational issues of such children, but does provide the reader with good references regarding this topic. One of the main strengths of the text is its emphasis on a team approach to ...

The present thesis investigated cognitive ability in children with severe to profound hearing impairment who have received cochlear implants (CIs). The auditory stimulation from a cochlear implant early in life influences most cognitive functions as a consequence of the plasticity of the brain in the young child. It is important to understand the cognitive consequences of auditory stimulation from CIs in order to provide adequate support to these children. This thesis examined three specific aspects of cognitive ability (working memory, phonological skill and lexical access), and reading ability in children with CIs, as compared to children with normal hearing in the same age. The relations between cognitive abilities and reading skills were also investigated, as well as the associations between demographic variables (e.g., age at implantation and communication mode), cognitive abilities and reading skills. The children with CI generally had lower performance levels than the normal hearing ...

The Hybrid cochlear implant (CI) has been developed for individuals with high frequency hearing loss who retain good low frequency hearing. Outcomes have been encouraging but individual variability is high; the health of the cochlea and the auditory nerve may be important factors driving outcome. Electrically evoked compound action potentials (ECAPs) reflect the response of the auditory nerve to electrical stimulation while electrocochleography (ECochG) reflects the response of the cochlear hair cells and auditory nerve to acoustic stimulation. In this study both ECAPs and ECochG responses were recorded from Nucleus Hybrid L24 CI users. Correlations between these two measures of peripheral auditory function and speech perception are reported. This retrospective study includes data from 25 L24 CI users. ECAPs and ECochG responses were recorded from an intracochlear electrode using stimuli presented at or near maximum acceptable loudness levels. Speech perception was assessed using Consonant-Nucleus
This update explores the importance of early auditory stimulation by considering the development of speech processing skills in profoundly deaf children who have received a cochlear implant. This literature is relevant to issues affecting children with Down syndrome, because like them, children with cochlear implants have hearing difficulties, but unlike the former, they do not have oral-motor issues.

A cochlear implant (CI) is an electronic device that can provide a sense of hearing to deaf or profoundly hearing impaired listeners by directly activating auditory nerve fibers. Optimal auditory performance with a CI requires subject-specific adjustments of several system parameters, i.e. the CI needs to be "fitted" to the individual user. A large number of system parameters is available to the clinician in the fitting software. For some of these parameters it is essential that they are individualized prior to switching on the device, since they ensure that sounds are audible without making sounds uncomfortably loud. For other parameters subject-specific optimization is less essential and a one-size-fits-all approach of using default settings results in good performance for the majority of CI users. However, these default settings may not always result in optimal settings for individual CI users and subject-specific fine-tuning of these parameter settings may further improve performance and/or ...

One of the things that attracted me to the Dept. of Speech and Hearing Science was the opportunity to do translational research. We have faculty members who come from a wide variety of backgrounds-neuroscience, engineering, linguistics, speech and language science, hearing science-focused on work that will address the challenges of people with communication disorders.. A cochlear implant is an auditory prosthesis for people who are severely to profoundly hearing-impaired. Originally, these implants were designed for people who were so deaf, they could only feel the sound that is amplified by a hearing aid. Cochlear implants change sound to electrical signals that are sent across the skin to an electrode array thats placed in the inner ear [the cochlea]. The electrodes are stimulated, which causes information to be sent to the auditory nerve and then on to the brain, where people process it.. Cochlear implants are not like eyeglasses, where you put them on and your vision is 20/20. The signal is ...
This project aims to improve access to care and increase patient empowerment by scaling up a successful service where people with cochlear implants are offered a personalised online support tool, home hearing test and support to adjust devices themselves.
During normal hearing, sound waves travel through the ear canal and strike the eardrum causing it to vibrate. The eardrum is attached to three tiny bones in the middle ear. The last bone, the stapes, pushes on a fluid-filled chamber in the inner ear, called the cochlea. This fluid movement causes sensitive hair cells within the cochlea to bend. When the hair cells bend, they generate an electrical signal that is sent to the brain. Disease, damage, or deformity of the cochlear hair cells is a common cause of hearing impairment or deafness. These malfunctioning hair cells may send intermittent or unclear signals to the auditory nerve, or send no signal at all. A device called a cochlear implant can restore hearing by replacing these damaged structures with a wire that is implanted in the cochlea. In order to stimulate the hearing process, sound waves are first received by a microphone unit, or speech processor, that hangs over the back of the ear. Within the processor, sound is filtered and ...

As was the case for first generation cochlear implants, early sight recovery devices have relied on straightforward signal processing and encoding schemes that assume that the transformation from stimulation to percept is virtually linear: these models presume that stimulating a grid of positions on the retina leads to the corresponding percept of a grid of luminous dots. However, a variety of psychophysical [19-24] and retinal  data, as well as the potential distortions described in this review, suggest that this linear scoreboard model is inadequate as an encoding model. To take the development of cochlear implant technology as a guide, a combination of psychophysical and neurophysiological research has led to dramatic improvements in cochlear implant coding schemes over the years. Indeed, for cochlear implants it could be argued that improvements in encoding have been as important as improvements in physical technology in improving perceptual outcomes [26,27].. Two main ways of ...
Everyone knows that hearing with two ears is better than one. Its not just common sense, its supported by scientific research.1-3. All ages can benefit from listening with two ears. It makes it easier to understand speech in noisy environments and to determine where sounds are coming from.. Cochlear implant recipients hear with both ears in two ways -- either bilaterally (with a cochlear implant in each ear) or bimodally (with a cochlear implant in one ear and a hearing aid in the other). Only AB and Phonak go beyond bilateral and bimodal hearing with Binaural VoiceStream Technology™.. ...
For many years scientists tinkered to find a perfect replacement for the damaged or dysplastic inner ear.

rise steadily, especially among children between the ages of 1 and 5. A cochlear implant is a surgically implanted device that stimulates the inner ear with electrical signals to the auditory nerve, which then sends signals to the brain where theyre translated into sounds. Unlike a hearing aid, which amplifies sound, cochlear implants compensate for damaged or non-working parts of the inner ear. The highly charged controversy about whether to get one and at what age has calmed to a general acceptance of individual choice. Now, a very small but growing percentage of the 90,000 people worldwide who have a cochlear implant are getting a second implant in their other ear. Adrean Mangiardi, a 25-year-old film major, is one of three RIT students with two implants. He got the first in his right ear when he was 15, and his second this spring..

An audio processing pipeline, for an auditory prosthesis, includes: a common stage, including a common frequency analysis filter bank, configured to generate a common set of processed signals based on an input audio signal; and first and second stimulator-specific stages, responsive to the common set of signals and including first and second frequency-analysis filter banks, configured to generate first and second sets of processed signals adapted for the first and second hearing stimulators, respectively.
other researchers have recently discovered that the areas of the brain responsible for processing vision or touch can recruit, or take over, areas in which hearing is normally processed, but which receive little or no stimulation in deafness. This is called "cross-modal" cortical reorganization and reflects a fundamental property of the brain to compensate in response to its environment. According to Dr. Sharma, "We find that this kind of compensatory adaptation may significantly decrease the brains available resources for processing sound and can affect a deaf patients ability to effectively perceive speech with their cochlear implants." Cochlear implants are implanted devices that bypass damaged portions of the ear and directly stimulate the auditory nerve. Signals generated by the implant are sent by way of the auditory nerve to the brain, which recognizes the signals as sound, according to the National Institutes of Health, which funds Dr Sharmas research. Next, Sharma and colleagues will ...

The bionic ear has been one of the most successful medical bionics devices; there are now over 450,000 recipients worldwide. However, the bionic ear has some shortcomings - particularly its performance for understanding speech in noisy environments and listening to music. Therefore, a substantial part of our research is aimed at improving the quality of hearing that can be provided with a cochlear implant, as well as with hearing aids. Using a multidisciplinary approach, our research program encompasses auditory neuroscience, development of new sound-processing strategies, and development of techniques that promote and maintain the surviving auditory neurons in cochlear implant recipients.. ...
New speech-to-touch sensory substitution device can improve hearing in hearing-impaired cochlear implant patients without any training, reveals a new study.
Each year many deaf children get a cochlear implant to connect to the world of sounds. So far, it was not clear which processes take place in these children when they start to learn language -- and why they differ in the level of language they achieve. Now, the Max Planck Institute for Human Cognitive and Brain Sciences found that deaf children with a cochlear implant learn words even faster than those with normal hearing.
Hosted by Boston Childrens Hospital and the Minuteman Implant Club, Inc.. Learners who use cochlear implants need help to succeed. They need encouragement in listening for meaning when young. They depend on remote microphones and voice-to-text supports for real-time access to spoken instruction in school. They face a menu of accommodations which they must choose and use wisely to improve their access to lectures and discussions in college. They show a variety of auditory, linguistic, and social skills which require different tools for success. This workshop is designed to familiarize educational teams with available tools to help them respond to the changing needs of learners who listen with cochlear implants as they advance in communication and in educational levels. The information to be presented also applies in many ways to students who use hearing aids.. Friday Schedule:. ...
Lydia Denworth, discusses the inspiration behind her new book I Can Hear You Whisper, which details her familys experience with her sons hearing loss and cochlear implant use.
An adaptive place-pitch ranking procedure for use with a cochlear implant or other neural stimulation system provides a systematic method for quantifying the magnitude and direction of errors along the place-pitch continuum. The method may be conducted and completed in a relatively short period of time. In use, the implant user or listener is asked to rank the percepts obtained after a sequential presentation of monopolar stimulation pulses are applied to a selected spatially-defined electrode pair. Should the patients judgment of pitch order be correct for all applied interrogations, then no further testing involving the tested electrode pair (two electrode contacts) is undertaken. However, should there be errors in the place-pitch ranking, which errors evidence perceptual place-confusions, then a search is undertaken for the spread of the perceptual confusion by separating the target channel and competing channel by one electrode contact at a time. This search for the spread of confusion

An apparatus (30) that can test external components of a cochlear implant system in a manner that does not require the person conducting the test to have advanced knowledge of the operation of the tested component. The apparatus provides a relatively quick and straightforward answer to the question of whether the component is operative or not. The testing apparatus (30) comprises at least one testing station (32,33,34) for receiving the component to be tested and makes an electrical and/or inductive connection thereto. A testing circuit is adapted to apply at least one test to the component and measure the response of the component to that test. The apparatus (30) compares the response of the component to stored data indicative of the response to the test of at least one equivalent component that is known to be operational and outputs a result of said comparison.

Method and apparatus for optically stimulating neurons of a plurality of auditory nerve pathways of a person to provide auditory sensations for the person by generating a plurality of pulsed light signals having one or more successive pulses. The spectrum of a detected audio signal is divided into M channels. In some embodiments, an N-of-M coding strategy is employed, where, for any given time frame, only N of the M channels are selected and illuminated to stimulate the auditory nerves. In some embodiments, the M channels are organized into bins, where, for any given time frame, only a maximum number of channels are illuminated per bin. This limits the number of illuminated channels-per-length of cochlea and therefore prevents localized heating of the cochlea and reduces power consumption of the device.
