There has been continued interest in clinical objective measures of binaural processing. One commonly proposed measure is the binaural interaction component (BIC), which is obtained typically by recording auditory brainstem responses (ABRs)—the BIC reflects the difference between the binaural ABR and the sum of the monaural ABRs (i.e., binaural (leftþ right)). We have recently developed an alte...

Rodents have proven to be a useful model system to screen genes, ototoxic compounds and sound exposure protocols that may play a role in hearing loss. High-throughput screening depends upon a rapid and reliable functional assay for hearing loss. This study describes the use of a frequency modulated (FM) chirp stimulus as an alternative to the click to derive a rapid assessment of auditory brain...

disease, I circulated among the principal practitioners of the town a series of questions, designed to elicit their experience. I received nineteen replies to my circular: thirteen of the nineteen gentlemen who favoured me with information had seen cases of fe,ver associated with a skin eruption. One had met with fifty cases, one with twenty, and the remainder with smaller numbers, varying from...

The binaural interaction component (BIC) of the auditory brainstem response (ABR) and BIC of the frequency-following response (FFR) to tonal stimuli were studied in normal-hearing adults. The ABR and BIC latencies from all subjects were consistently shorter to the click-like sound than to the 2.0 kHz tone burst. Increasing stimulus presentation rate produced longer latencies and diminished ampl...

Auditory feedback influences the development of vocalizations in songbirds and parrots; however, little is known about the development of hearing in these birds. The auditory brainstem response was used to track the development of auditory sensitivity in budgerigars from hatch to 6 weeks of age. Responses were first obtained from 1-week-old at high stimulation levels at frequencies at or below ...

Endomorphism algebras gure prominently in group representation theory. F or example, if G is a nite group of Lie type, the representation theory of the endomorphism algebra End G Cj G B |sometimes known as the Hecke algebra over C of G|plays a central role in unraveling the complex unipotent c haracters on G 22, 77. Another example arises in the modular representation theory of the nite general...

The glucose analogue 2-deoxy-I)-glucose {2-1X5) was used as a means of producing intracellular bypoglycemia in eight normal male volunteer subjects during a control period, immediately following their initial exposure to acceler...

The auditory brainstem response (ABR) to clicks is widely used for early detection of hearing loss in the child at risk for hearing dysfunction, but there is a lack of direct, large-sample estimates of test accuracy. In this report, results and preliminary analyses are presented that relate click ABR thresholds obtained at 3 to 12 months corrected age to detailed follow-up behavioral puretone a...

i p m t t t a f o r m r t ntracardiac pacemaker implantation was first described a alf century ago; the same authors first reported on transelephonic monitoring (TTM) of such devices a dozen years ater (1,2). Follow-up of the pacemaker patient was recogized as critical, particularly in view of the uncertain eliability associated with leads and generators. Tracking evice longevity and function h...

BACKGROUND Bilateral Meniere's disease (MD) is still controversial due to different criteria used to assess the involvement of the primarily affected ear and the contralateral one. We evaluated the percentage of bilateral forms in 49 patients with MD. METHODS 49 patients with (MD) were studied. All were selected according to the following requirements: history, tonal audiometry, glycerol test...
