Jeffrey Skidmore ; Dyan Ramekers ; Deborah Colesa ; Kara Schvartz-Leysac ; Bryan E. Pfingst ; Shuman He |Amplitudes of electrically evoked compound action potentials (eCAPs) as a function of the stimulation level constitute the eCAP amplitude growth function (AGF). The slope of the eCAP AGF (i.e., rate of growth of eCAP amplitude as a function of s[...]Article

Shuman He ; Lei Xu ; Jeffrey Skidmore ; Xiuhua Chao ; William Riggs ; Ruijie Wang ; Chloe Vaughan ; Jianfen Luo ; Michelle Shannon ; Cynthia Warner |Objectives: The aim of this study is to (1) investigate the effects of increasing the pulse phase duration (PPD) on the neural response of the electrically stimulated cochlear nerve (CN) in children with CN deficiency (CND) and (2) compare the r[...]Article
Viral D. Tejani ; Jeong-Seo Kim ; Christine Etler ; Jeffrey Skidmore ; Yi Yuan ; Shuman He ; Marlan R. Hansen ; Bruce J. Gantz ; Paul J. Abbas ; Carolyn J. Brown |Objective: Minimally traumatic surgical techniques and advances in cochlear implant (CI) electrode array designs have allowed acoustic hearing present in a CI candidate prior to surgery to be preserved postoperatively. As a result, these patient[...]Article
Objective: This study aimed to investigate the associations between advanced age and the amount and the speed of neural adaptation of the electrically stimulated auditory nerve (AN) in postlingually deafened adult cochlear implant (CI) users. [...]Article
Objective: This study investigated the effects of two temporal response properties of the auditory nerve (i.e., neural adaptation and recovery from neural adaptation) on speech perception performance in postlingually deafened adult cochlear impl[...]Article
Jeffrey Skidmore ; Lei Xu ; Xiuhua Chao ; William Riggs ; Angela Pellitieri ; Chloe Vaughan ; Xia Ning ; Ruijie Wang ; Jianfen Luo ; Shuman He |Objectives: This study aimed to create an objective predictive model for assessing the functional status of the cochlear nerve (CN) in individual cochlear implant (CI) users. Design: Study participants included 23 children with cochlear nerve[...]Article
Shuman He ; Yi Yuan ; Jeffrey Skidmore |Objective: As a step toward identifying the origin of the across-electrode variation in within-channel gap detection thresholds (GDTs) measured in individual cochlear implant (CI) users, this study assessed the relationships between the auditory[...]Article
Objective: This study assessed the relationships between the salience of amplitude modulation (AM) cues encoded at the auditory nerve (AN), perceptual sensitivity to changes in AM rate (i.e., AM rate discrimination threshold, AMRDT), and speech [...]Article
Objectives: This study aimed to determine the effect of advanced age on how effectively a cochlear implant (CI) electrode stimulates the targeted cochlear nerve fibers (i.e., the electrode-neuron interface [ENI]) in postlingually deafened adult [...]Article
Objective: This study reports two potential biomarkers of the physiological status of the cochlear nerve (CN) in cochlear implant users. Design: This project represents a complementary analysis on a subset of electrophysiological data from ou[...]Article
Shuman He ; Lei Xu ; Jeffrey Skidmore ; Fuh-Cherng Jeng ; et al. |Objectives: This study aimed to compare the effects of increasing the interphase gap (IPG) on the neural response of the electrically stimulated cochlear nerve (CN) between children with CN deficiency (CND) and children with normal-sized CNs. [...]Article
Lei Xu ; Jeffrey Skidmore ; Jianfen Luo ; Xiuhua Chao ; Ruijie Wang ; Haibo Wang ; Shuman He |Objective: This study aimed to (1) investigate the effect of pulse polarity on neural response of the electrically stimulated cochlear nerve in children with cochlear nerve deficiency (CND) and children with normal-sized cochlear nerves and (2) [...]Article
Objective: This study assessed the relationship between electrophysiological measures of the electrically evoked compound action potential (eCAP) and speech perception scores measured in quiet and in noise in postlingually deafened adult cochlea[...]Article
William Riggs ; Chloe Vaughan ; Jeffrey Skidmore ; Sara Conroy ; Angela Pellittieri ; Brittney Carter ; Curtis J. Stegman ; Shuman He |Objectives: This study aimed to investigate effects of aging and duration of deafness on sensitivity of the auditory nerve (AN) to amplitude modulation (AM) cues delivered using trains of biphasic pulses in adult cochlear implant (CI) users.
