Figure 1. A diagram of a cochlear implant, which is composed of external and internal portions. The external portion contains a microphone and signal processor (shown behind the ear) and a transmission coil (located above the ear) that sends the coded signal across the skin to the implanted ...
It comprises two distinct parts, the cochlear nerve and the vestibular nerve, each subserving a different function. The two parts emerge from the anterolateral aspect of the brainstem at the ponto-medullary junction, lateral to the site of emergence of the facial nerve. The cochlear nerve is ...
FIG. 4 is a side view illustrating the cochlear ear implant including a behind-the-ear module; FIG. 5 is an additional side view illustrating the cochlear ear implant of the present invention including a behind-the-ear module; FIG. 6 is a block diagram illustrating the operation of a ...
Cochlear implant (CI) users typically achieve satisfactory speech intelligibility in quiet environments such as a sound booth used for testing in audiology clinics. However, they encounter difficulty hearing and comprehending speech in noisy social settings. There have been significant efforts towards the ...
FIGS. 2A and 2B, respectively, show a cochlear implant system and a partial functional block diagram of one embodiment of a cochlear stimulation system, which may incorporate the system of the present invention and implement the method of the present invention for conveying fine time structure in...
To solve this problem, we attempted to establish a large animal model for ABIs in a rhesus macaque monkey to explore the array of the cochlear nucleus (CN) complex, which would thus lay the foundation for the investigation of the mechanisms of auditory recovery after implant surgery. Auditory ...
a Schematic representation of an in vivo experimental setup for the full-custom fully implantable cochlear implant system. where the intracochlear electrodes were surgically placed to the cochlea of the animal model. The piezoelectric sensor was mounted on a parylene membrane, which is placed on a ...
hearing aid devices with implant parts which are implantable into the body of a user and adapted to wirelessly communicate with the external part of the hearing aid device, e.g., for a hearing aid device with a cochlear implant, as these kind of hearing aid devices may comprise two ...
i.e. acoustic, electrical and/or mechanical. These different stimulation modes may be applied ipsilaterally or contralaterally. In the embodiment shown in FIG. 2, multimodal implant200provides acoustic and electrical stimulation, although other combinations of modes are contemplated by this invention. ...
