Book Description
Abstract: Bilateral cochlear implants (BiCIs) are becoming more common recently and have been proven to provide improvements in speech perception in noise and sound localization. However, benefits to sound localization for BiCI listening are mainly from the perception of interaural level differences while interaural time difference (ITD) sensitivity is very limited. To help understand this, the current modeling study focused on the following characteristics of neurophysiological data from ITD-sensitive neurons in acutely deafened animal models with BiCIs: (1) rate-limitation of ITD sensitivity to constant-amplitude pulse trains, (2) intensity dependence of ITD sensitivity, and (3) effect of amplitude modulation on ITD sensitivity with high-rate stimulation. A network of model neurons was used to study binaural responses to electrical stimulation. Our working hypothesis was that central auditory processing is normal so that the abnormality in the response to the electric stimulation at the level of the auditory nerve fibers (ANFs) is the source of the limited binaural response. A descriptive model of ANF response to electric stimulation was implemented and used as an input to a network of model neurons in the ascending auditory pathway, up to the inferior colliculus (IC). The result shows that ITD sensitivity depends strongly on the specific configurations of membrane and synaptic parameters for different input stimulation rates. Stronger excitatory synaptic inputs and a faster membrane response are required for the model neurons to be ITD-sensitive at high stimulation rates, both in electric and acoustic stimulation. This raises the possibility of frequency-dependent differences in neural mechanisms of binaural processing; limitations in ITD sensitivity may be due to the mismatch between stimulation rate and cell parameters in ITD-sensitive neurons. The high spike rate and phase-locking at the ANF to electric stimulation changes the rate-ITD tuning at the IC. Amplitude modulation of the high-rate stimulation restores the ongoing ITD sensitivity by effectively reducing the spike rate in the ANF. ITD sensitivity to temporal fine-structure is restored in the model with amplitude-modulated high-rate stimulation, consistent with physiological results. Overall, this study suggests that fine-structure ITD can be delivered to BiCI users with proper processing strategies.
