Cervical Vestibular-Evoked Myogenic Potentials (Cvemps): "Differentiation Of Inter-Neck Emg Symmetry Between Children And Adults", Ellen Jones
Senior Honors Projects, 2010-2019
A cervical Vestibular-Evoked Myogenic Potential (cVEMP) is one of the few objective vestibular diagnostic tests available for pediatric populations. This test evaluates the functionality of the saccule end organ through an inhibitory reflex on the sternocleidomastoid (SCM) muscle that inhibits the level of electromyographic (EMG) activity (Wiener-Vacher, 2013). Because the saccule response is measured as an inhibition of EMG in the SCM, it is imperative that the SCM have a tonic contraction prior to eliciting the response and that the contraction of the SCM is equal on the right and left sides. It is generally accepted that young, healthy adults …
Build-Up Effect Of Auditory Stream Segregation Using Amplitude-Modulated Narrowband Noise, Harley J. Wheeler
Build-Up Effect Of Auditory Stream Segregation Using Amplitude-Modulated Narrowband Noise, Harley J. Wheeler
Senior Honors Projects, 2010-2019
Recent psychoacoustic experiments (Böckmann-Barthel et al., 2014; Deike et al., 2012) have re-examined research regarding stream segregation and the build-up effect. Stream segregation is the ability to discern auditory objects within a stream of information, such as distinguishing one voice amongst background noise or an instrument within an orchestra. Initial works examining this topic proposed that auditory information is not immediately distinguished as various streams, but rather that differences accumulate over time, allowing listeners to segregate information following a period of build-up (i.e., the build-up effect); whereas more current findings indicate a build-up period is unnecessary for segregation. This experiment’s …
Pre-Pulse Inhibition Assessment Of Sound Localization In Mice, Kathryn C. Brooks
Pre-Pulse Inhibition Assessment Of Sound Localization In Mice, Kathryn C. Brooks
Senior Honors Projects, 2010-2019
The purpose of my Honors Research Project was to assist Dr. Megan
Klingenberg in completing part of the research in her final dissertation project. Dr.
Klingenberg’s project was based off of a study done by Allen and Ison in 2010.
This study tested the auditory spatial acuity of mice using pre-pulse inhibition of
the startle reflex as the response for detecting the sound stimulus. The goal of
Dr. Klingenberg’s AuD project was “to explore the methodological, functional, and
genetic influences on sound localization using pre-pulse inhibition of the acoustic
startle response in mice”. Dr. Klingenberg’s project was broken into three …
