Sensory Substitution Devices (SSDs) convey visual information through sounds or touch, thus theoretically enabling a form of visual rehabilitation in the blind. However, for clinical use, these devices must provide fine-detailed visual information which was not yet shown for this or other means of visual restoration. To test the possible functional acuity conveyed by such devices, we used the S...
The use of bone-anchored hearing aids is not possible for all patients who wear an implant-retained auricular prosthesis. For some patients, the external ear canal cannot be occluded with a conventional hearing device. Currently manufactured hearing aids may not readily fit the contours of an implant-retained auricular prosthesis. This article describes a technique that allows a modular hearing...
The auditory system of adult listeners has been shown to accommodate to altered spectral cues to sound location which presumably provides the basis for recalibration to changes in the shape of the ear over a life time. Here we review the role of auditory and non-auditory inputs to the perception of sound location and consider a range of recent experiments looking at the role of non-auditory inp...
Hand loss is a highly disabling event that markedly affects the quality of life. To achieve a close to natural replacement for the lost hand, the user should be provided with the rich sensations that we naturally perceive when grasping or manipulating an object. Ideal bidirectional hand prostheses should involve both a reliable decoding of the user's intentions and the delivery of nearly "natur...
The cochlear implant can restore speech perception in patients with sensorineural hearing loss. However, it is ineffective for those without an implantable cochlea or a functional auditory nerve. These patients can be implanted with the auditory brainstem implant (ABI), which stimulates the surface of the cochlear nucleus. Unfortunately, the ABI has achieved limited success in its main patient ...
The auditory processing of different phonemes is an important listening skill, which is usually already acquired in early childhood (Kuhl, 2004). These developments, in turn, affect a variety of other skills as speech development and normal acquisition of literacy skills (Eimas, 1985). Early detection and intervention of hearing disorders as well as advanced technology of auditory prosthesis li...
We investigated fast wave propagation in auditory cortex of an alert cat using a chronically implanted microelectrode array. A custom, real-time imaging template exhibited wave dynamics within the 33-microwire array (3 mm(2)) during ten recording sessions spanning 1 month post implant. Images were based on the spatial arrangement of peri-stimulus time histograms at each recording site in respon...
implant-supported craniofacial prostheses are made to restore defective areas in the face and cranium. this clinical report describes a technique for fabrication of an orbital prosthesis with three adjacent implants in the left lateral orbital rim of a 60-year-old woman. selection of appropriate attachment system (individual magnetic abutments versus bar-clip attachment) for implant-supported o...
dental implants have provided exceptional rehabilitative options for edentulous and partially edentulous patients. however, as more implants come into play, the more the clinicians come across problems where specific considerations must be taken into account to meet expectations. the toronto bridge is a treatment modality proposed for restoring several teeth lost in patients with increased crow...
We developed and tested a brain-computer interface for control of an artificial speech synthesizer by an individual with near complete paralysis. This neural prosthesis for speech restoration is currently capable of predicting vowel formant frequencies based on neural activity recorded from an intracortical microelectrode implanted in the left hemisphere speech motor cortex. Using instantaneous...
