This book was released on 2011 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study examined and compared the effect of the contralateral stimulation of the auditory efferent system on the cochlear microphonics (CM) versus the distortion product otoacoustic emissions (DPOAEs). The DPOAEs and the CM were recorded from the right ear of 16 normal-hearing young female adults with and without 60 dB sound-pressure-level (SPL) broad band noise (BBN) in the left ear. DPOAEs were obtained at 0.5, 2, and 4 kHz, with L1 = 65 dB SPL and L2 = 50 dB SPL, and f2/f1 ratio = 1.2. The CM was recorded from the right tympanic membrane at 90 dB SPL using three stimuli (click and 0.5 and 2 kHz tone bursts) and two polarities (condensation and rarefaction). Results showed both suppression and enhancement of the DPOAE and the CM responses in the presence of BBN, but the effect was not statistically significant at any of the tested conditions. When the ratio of the suppression or enhancement was used, the effect was marginal for the 2 kHz TB stimulus of the CM. Results also showed a possible relation between the stimulus polarity and the type of effect on the CM. In conclusion, there is some evidence that the efferent system is involved in the suppression and enhancement of the CM, mainly at 2 kHz TB. This might be due to the nature of the CM recording from the basal turn of the cochlea. This study provided the first descriptions of the contralateral suppression of CM in humans. More research is needed to enhance the sensitivity of the CM test methodology to examine the function of the efferent system clinically.

Download or read book Frequency Specificity of Contralateral Suppression of Distortion Product Otoacoustic Emissions written by Lisa Arnelle Ross and published by . This book was released on 2013 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The frequency specificity of the contralateral suppression effect as demonstrated in DPOAEs was measured in 20 adult participants using contralateral stimuli consisting of white noise, and. 5, 1, 2, and 3 kHz tones with presentation levels of 40, 50, and 60 dB SPL. A significant suppression effect was found with white noise in the low frequencies (1.125 to 2.531 kHz) as well as higher frequencies (5.062 to 6.328 kHz). While not reaching a level of significance, 2 and 3 kHz demonstrated a similar suppression as white noise in the higher frequencies (5.062 to 6.328 kHz) and a non-significant enhancement effect was observed in the low frequencies (2.015 to 2. 812 kHz). Future studies of contralateral suppression should examine BBN with various high frequency cut offs in order to more fully examine these phenomenon.

Available in PDF, EPUB and Kindle. Book excerpt: Knowledge about the structure and function of the inner ear is vital to an understanding of vertebrate hearing. This volume presents a detailed overview of the mammalian cochlea from its anatomy and physiology to its biophysics and biochemistry. The nine review chapters, written by internationally distinguished auditory researchers, provide a detailed and unified introduction to sound processing in the cochlea and the steps by which the ensuing signals are prepared for the central nervous system.

This book was released on 2016-09-06 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main function of the sensory systems is the transducing of external stimuli into bioelectrical signals, which are conducted through afferent pathways from sensory epithelia to the brain. However, it is known that descending projections are ubiquitous in the different sensory modalities, and in the case of auditory efferents connect the cerebral cortex with sensory receptor cells. Several functions have been attributed to the efferent system, including protection to acoustic trauma, unmasking of auditory stimuli in background noise, balance of interaural sensitivity and some cognitive functions like modulation of cochlear sensitivity during selective attention to auditory or visual stimuli. In addition there is evidence of a possible involvement of the efferent system in the etiology or treatment of some clinical pathologies like tinnitus. In this e-book, entitled “Auditory Efferent System: New Insights from Cortex to Cochlea”, we aimed to give an overview of the advances concerning the descending projections from the auditory cortex to subcortical nuclei and the olivocochlear system. In addition, different theoretical proposals of efferent functions are presented. We think that this e-book is an important contribution to the understanding of the efferent system in mammals, merging auditory-cortex literature with studies performed in the olivocochlear system.
