COCHLEAR INITIATION SITES OF THE HUMAN AUDITORY FREQUENCY FOLLOWING POTENTIALSMcDermott, John Charles January 1980 (has links)
The frequency following potential (FFP) is an auditory evoked response which crudely replicates the waveform of the stimulus. The origins of this far-field potential have been localized to the cochlea and specific auditory nuclei. The initiation site of the FFP along the cochlear partition has been thought to be dependent upon stimulus sound pressure level. Low stimulus levels elicit FFP from the apical turn of the cochlea, while moderate and high stimulus levels may elicit FFP from a large segment of the partition, including the basal turn. Simultaneous masking studies have contributed to the knowledge of this potential, but results from these studies may be confounded by interference from bioelectric potentials generated by distortion products from the masking noise. This investigation used non-simultaneous masking tones set at the subject's pulsation threshold level (PTL). This psychophysical method provides a representation of the frequency-resolving properties of the auditory periphery in a repeated gap masking paradigm. Patterns of the relative masking effect of each masking tone were plotted and compared for several probe levels and in the presence or absence of a continuous, high-pass masking noise. Tuning patterns derived in high-pass making noise effectively represented apical turn FFP. Those patterns without masking noise represented whole-cochlea FFP. The results of this study demonstrarted tuning patterns that reflected diminished FFP amplitudes in the primary 500 Hz region as well as in an extended secondary range of 800 to 2000 Hz, depending on the stimulus-masking parameters. Tuning patterns in high-pass masking noise were consistently flatter in the primary and secondary regions than for the tuning patterns without masking noise. The secondary regions of the tuning patterns extended above 2000 Hz for the patterns obtained without high-pass masking. Tuning patterns were consistently broader for the high stimulus level than for the moderate stimulus level. The multiple cochlear initiation sites for the FFP preclude its use as an audiological tool for the assessment of low-frequency hearing. However, the potential is suggested as a method to assess whole-cochlear response for the difficult-to-test patients with suspected profound hearing loss.

The effects of high repetition rate stimuli on electrocochleography performed on normal hearing subjectsBowker, Caren Anne 17 August 2016 (has links)

In partial fulfillment of the requirements for the degree of Master of
Arts by coursework in Audiology
June 1999 / High stimulus repetition rates have been proposed as a solution to the poor sensitivity and
specificity of the standard electrocochleogram. The use of this approach has been
confounded, however, by conflicting literature reports on the effects of high stimulus
repetition rates on normal subjects. This study aimed to confirm the effects of high stimulus
repetition rates on normal hearing subjects as a precursor to clinical high stimulus repetition
rate electrocochleography trials. Electrocochleogram tracings were recorded binaurally from
51 normal hearing subjects at 7.1 cps, 51.1 cps, 101.1 cps and 151.1 cps and the
summating potential and action potential latencies and amplitudes, summating
potential/action potential amplitude ratios and waveform widths were recorded. Statistical
analyses showed that increasing the stimulus repetition rate caused statistically (p<O.05) and
clinically (p<O.O1 for latency and p<O.005 for amplitude) significant changes to the action
potential latency and amplitude, summating potential/action potential amplitude ratio and
waveform width, but caused only limited statistical (p<O.05) and clinical (p<O.OI for
latency and p<O.005 for amplitude) changes to the summating potential amplitude and
latency. Subject age had no effect on the results and there was no interaction between age
and stimulus repetition rates. These findings provide the most comprehensive data on the
effects of fast stimulus repetition rates to date, and have provided the beginnings of a valid
clinical normative database for high stimulus repetition rate tympanic electrode
electrocochleography.
