The audiologic performance of 54 postlingually deafened adults wearing cochlear implants was uniformly evaluated. The participants had 9 months' or more experience with one of five different cochlear prostheses (Los Angeles Single Channel (N = 11), Vienna Single Channel (N = 4), Melbourne Multichannel (N = 18), Utah Multichannel (N = 19), San Francisco(More)
An attempt was made to reconstruct the central events that occurred in the various stages of vestibular compensation after a bilateral labyrinthectomy in the cat. Bilateral labyrinthectomized cats showed no nystagmus, but had unsteady head movements and wide gaits. Neural activity in both sides of the medial vestibular nuclei (MVN) was depressed during the(More)
The purpose of this investigation was to determine the influence of two types of attention-requiring tasks on vestibular nystagmus elicited by caloric stimulation: mental arithmetic and a short conversation. The subjects were divided into four groups according to stimulus paradigm and task. It was found that conversation was consistently superior to mental(More)
This is a study of the effects of repeated angular acceleration on the activity of vestibular nuclei units in anesthetized and in conscious cats. The experimental animals were subjected to trains of repeated and consecutive constant acceleration-deceleration ramps (4-8 degrees/sec2). In a few cases nystagmus was recorded along with extracellular unit(More)
We tested six patients with single channel cochlear implants on several tests from the Minimal Auditory Capabilities battery and the Iowa Cochlear Implant Tests. All patients were able to discriminate some everyday sounds and to identify the number of syllables in the words presented. Five patients were able to identify speaker sex reliably. Surprisingly,(More)
Before exploratory tympanotomy, it is difficult to diagnose an idiopathic perilymph fistula (PLF) because of its variable presentations. An animal model tube-PLF on guinea pigs was established to evaluate the change of the sensitivity of the cochlea function and the value of the postural audiometry in PLF. A fine polyethylene tube (O.D. 0.6mm) was inserted(More)
The monothermal differential caloric test allows determination of vestibular recruitment and decruitment, variables which may help discriminate peripheral from central vestibular lesions. Previous reports indicated a strong association between vestibular recruitment and Menière's disease. This study examined patients having unilateral Menière's disease.(More)
It is now clear that cochlear implants can provide useful hearing for profoundly deaf adults, and that multichannel devices give the brain more information than most single-channel devices. We are in a dilemma as to how to compare the many multichannel devices, because of the language barrier. Virtually no multichannel wearer is equally testable in two, let(More)
Cochlear implants have become a realistic alternative for the management of profoundly deaf patients. A variety of implants with differing electrode designs and coding strategies have been developed by nine major implant centers around the world. Each center has their "star" patient, but objective comparisons between these different implant designs are(More)
We tested four patients using the single-channel cochlear implant from Los Angeles, three patients using the single-channel cochlear implant from Vienna, and two patients using the multichannel cochlear implant from Melbourne. Tests from the MAC battery and the Iowa Cochlear Implant Battery were used. Most patients were able to identify some environmental(More)
