Hearing asymmetry and auditory acuity
right auditory inputs to locate their prey or mates, the reasonable expectation is that ears should remain symmetrical. However, this is not always the case, and in some animals auditory asymmetry has been shown to be adaptive, improving localisation for specialised tasks. For example, the vertical asymmetrical placement of the external auditory meatus in some species of nocturnal owls increase...
متن کاملAuditory nerve perinodal dysmyelination in noise-induced hearing loss.
Exposure to loud sound (acoustic overexposure; AOE) induces hearing loss and damages cellular structures at multiple locations in the auditory pathway. Whether AOE can also induce changes in myelin sheaths of the auditory nerve (AN) is an important issue particularly because these changes can be responsible for impaired action potential propagation along the AN. Here we investigate the effects ...
متن کاملSelective electrical stimulation of the auditory nerve activates a pathway specialized for high temporal acuity.
Deaf people who use cochlear implants show surprisingly poor sensitivity to the temporal fine structure of sounds. One possible reason is that conventional cochlear implants cannot activate selectively the auditory-nerve fibers having low characteristic frequencies (CFs), which, in normal hearing, phase lock to stimulus fine structure. Recently, we tested in animals an alternative mode of audit...
متن کاملAuditory Perceptibility: Acuity and Dominance
determination of gross auditory perceptibility of value to clinicians, generally. It is not demanded of the clinical psychologist that he compete with the aurist, but if a correct diagnosis is to be made he must establish the degree of auditory perceptibility3 and recognize the handicaps of reduced auditory acuity to effect necessary school adjustments and to stress the need for medical care. T...
متن کاملTitle : 1 Auditory Temporal Acuity
26 Cochlear implants stimulate the auditory nerve with amplitude-modulated electric pulse 27 trains. Pulse rates >2000 pulses per second (pps) have been hypothesized to enhance 28 transmission of temporal information. Recent studies, however, have shown that higher 29 pulse rates impair phase locking to sinusoidal amplitude modulation in the auditory 30 cortex and impair perceptual modulation d...
