• A Comparison of Acoustic and Electric Reflex Thresholds (ESRT) Scottsdale/Phoenix, Ariz., Rochester, Minn.

  The purpose of this study is to analyze immittance patterns, both acoustically and electrically, for patients with either cochlear implantation or auditory brainstem implantation.

   

• Assessing Eye Tracking Features Following Sports-Related Concussion Scottsdale/Phoenix, Ariz.

  This proposal aims to describe the oculometric features present during King-Devick (K-D) testing for subjects who experienced sports-related concussion. The investigators aim to better describe the underlying oculomotor anomalies present in this cohort that lead to increased K-D test time. Understanding these anomalies will allow for better understanding of the effects of sports-related concussion and may provide a rapid and reliable metric for diagnosing concussion as well as monitoring long-term recovery.

• Comparison of Standard Visually Evoked Potential (VEP) Recording and a Portable VEP System Scottsdale/Phoenix, Ariz.

  Visually Evoked Potentials (VEPs) are electrical potentials elicited from brief visual stimuli and recorded from the visual cortex with surface electrodes.  VEPs are an objective, reliable, and non-invasive method for evaluation of the functional integrity of the retina and early afferent visual pathways. The purpose of this study is to compare the VEPs generated from a standard clinical evoked potential system to those obtained from the Vivonics portable VEP system.
