Book The Role of the Human Auditory Middle Latency Response in Auditory Novelty Detection

Download or read book The Role of the Human Auditory Middle Latency Response in Auditory Novelty Detection written by Heike Corinna Althen and published by . This book was released on 2014 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: One way of structuring the huge amount of sound input reaching the human ear, is extracting sound objects, which are formed by stimuli having a certain regularity in common. Mismatching stimuli are detected pre-attentively and can trigger an involuntary attention switch towards them. The auditory-event related potential which reflects the process of detecting mismatching sounds is called mismatch negativity (03N), usually peaks at 150 to 250 ms from stimulus onset and has bilateral sources in auditory and prefrontal cortex. 03N is elicited by deviants violating auditory regularities, like in a simple "oddball paradigm", which is composed of unchanging repetitive "standard" sounds and rare, randomly occurring, deviating sounds (so called deviants), as well as by violations of more complex auditory regularities. Recently it has been shown that also the middle latency response (MLR), which is an earlier auditory evoked potential (AEP), reflects the occurrence of deviating sounds in an oddball paradigm. The objective of the present thesis was to examine the role of the middle latency response in the auditory deviance detection system. The first study showed that lower intensity deviants of an oddball paradigm elicited a slight negativity at the transition from the Na to the Pa wave, in comparison to the response elicited by physically identical standard stimuli. In addition, an 03N was elicited. In the second study a hypercomplex invariance, more concretely, a feature-conjunction paradigm with two types of standard stimuli, each with a distinct combination of stimulus frequency and stimulus source location, and two types of deviant stimuli, each with the frequency of one standard stimulus, and the location of the other, were presented. In order to compare the results with MLRs elicited by stimuli of a simple auditory regularity, an additional simple oddball paradigm with frequency deviants was presented. The Nb wave of the MLR was enhanced in response to frequency deviants compared to standard stimuli of the simple oddball paradigm. However, comparison of the MLRs to deviants and standards of the feature-conjunction paradigm yielded no differences. An 03N was elicited in both paradigms. In the third study the application of a variation of the multi-feature paradigm for MLR studies and the MLR in response to frequency-intensity double deviants were probed. Frequency-intensity double deviants elicited a significant enhancement of the MLR, which was as large as the sum of the enhancements elicited by the frequency and intensity single deviants. The results of the present thesis suggest that the early deviance detection at the level of the MLR occurs only for simple auditory regularities, as in the case of feature repetitions in the simple oddball paradigm, or in the multi-feature paradigm, where formation of the standard trace does not require extracting feature-combinations. Furthermore, the results suggest that deviations in frequency and intensity are processed independently from each other. Based on evidence from the present thesis and from other studies, we conclude that the regularity encoding and deviance detection of stimuli presented in more complex auditory regularities than the simple oddball or the multi-feature paradigm require higher-order brain mechanisms than those reflected in the MLR. This goes in line with the hypothesis of a hierarchically organized auditory novelty system. Concerning the cellular mechanisms underlying auditory deviance detection, it has been proposed that stimulus-specific adaptation (SSA) to stimulus probabilities observed in animal auditory subcortical and cortical structures could be the single neuron correlate of the deviance-related activity in the human AEP due to its similar characteristics to 03N. However, since the latencies of the MLR better match the latencies of SSA, it is probable that the deviance-related modulations in the MLR represent a more direct correlate of the early cellular SSA, than 03N.

Available in PDF, EPUB and Kindle. Book excerpt: Auditory Brainstem Evoked Potentials: Clinical and Research Applications provides a solid foundation of the theoretical principles of auditory evoked potentials. This understanding is important for both the development of optimal clinical test strategies, and interpretation of test results. Developed for graduate-level audiology students, this comprehensive text aims to build a fundamental understanding of auditory evoked brainstem responses (ABR), and their relationship to normal and impaired auditory function, as well as its various audiologic and neurootologic applications. In addition to covering the classical onset ABR, the book provides a thorough review of sustained brainstem responses elicited by complex sounds, including auditory steady state response (ASSR), envelope following response (EFR), and frequency following response (FFR), and the growing clinical and research applications of these responses. By exploring why certain stimulus manipulations are required to answer specific clinical questions, the author provides the resources needed for students and clinicians to make reasoned decisions about the optimal protocol to use in a given situation. Key Features: * A full chapter devoted to laboratory exercises * Numerous illustrations to help explain key concepts * Description of neural bases underlying amplitude and latency changes * Troubleshooting techniques * End-of-chapter summaries

Book The Middle Latency Response  MLR  and Steady State Evoked Potential  SSEP  in Neonates

Download or read book The Middle Latency Response MLR and Steady State Evoked Potential SSEP in Neonates written by R. C. Fifer and published by . This book was released on 1985 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the characteristics of the middle latency response (MLR) and the related steady state evoked potential (SSEP) in a total of 36 neonates. The reports of previous investigators have cast doubt on the existence of both the MLR and SSEP in neonates. The measurements in these studies were obtained, however, using stimulation and recording parameters that are appropriate for adults. Since virtually all other aspects of neonate audition differ significantly from comparable adult attributes, one goal of this study was to determine the appropriate parameters with which to obtain a valid MLR and SSEP in very young children. Other goals of this study included: (1) evaluation of two different algorithms for low-frequency sensitivity prediction using the SSEP; (2) investigation of the stability of the SSEP over repeated trials; and (3) elucidation of the relationship the neonatal MLR to later occurring auditory evoked potentials.
