For 11 bilateral cochlear-implant listeners, ITD thresholds for number-matched interaural electrode pairs were measured at five places along the array. On these same electrodes, the most comfortable current level used for stimulation (C-level), electrically evoked compound action potentials (ECAPs), and electrode positions relative to the modiolus based on computed-tomography scans were recorded. Monaural predictors included stimulation level (quantified by C-levels), modiolar distance (related to the width of neural activation), and efficacy of auditory nerve fiber responses to electrical stimulation [ECAP amplitude growth function (AGF) slopes]. Binaural predictors included the degree of interaural asymmetry in both C-levels and modiolar distances. It was hypothesized that better ITD sensitivity would be related to higher C-levels and larger modiolar distances (because of increased loudness and broader neural activation), steeper ECAP AGF slopes (because of more numerous and healthy neurons), and smaller interaural asymmetry (because of a larger proportion of binaurally excited neurons). The hypotheses were tested via backwards elimination in mixed-effects models with bias and stability analyses performed using bootstrapping. Partially confirming the hypotheses, higher C-levels and greater modiolar distance for electrodes in the ear with better ENI (as defined primarily by the ECAP AGF slope) were significantly associated with better ITD thresholds. These results highlight the role of monaural processing in binaural performance.<\/jats:p>","DOI":"10.1177\/23312165261487553","type":"journal-article","created":{"date-parts":[[2026,10,14]],"date-time":"2026-10-14T12:58:52Z","timestamp":1791982732000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Predicting Interaural Time Difference Sensitivity for Bilateral Cochlear-Implant Listeners From Loudness Levels and Factors Reflective of the Electrode-to-Neural Interface"],"prefix":"10.1177","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-5994-5099","authenticated-orcid":false,"suffix":"II","given":"Bobby E.","family":"Gibbs","sequence":"first","affiliation":[{"name":"University of Wisconsin-Madison"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-5872-283X","authenticated-orcid":false,"given":"Miranda","family":"Cleary","sequence":"additional","affiliation":[{"name":"University of Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joshua G.
