TLDR
These findings have demonstrated that the brain can integrate electrical stimulation from the two ears, and it is now appropriate to begin experimental studies of binaural cochlear implants.Abstract:
Purpose of reviewProviding a unilateral cochlear implant in a patient with a profound bilateral hearing loss has now been a standard clinical practice for more than a decade. Although results are often very good, normal hearing has not been restored. One exciting opportunity to improve hearing in thread more

Tissue and electrode capacitance reduce neural activation volumes during deep brain stimulation.
TL;DR: The results and methodology of this study provide the foundation for the quantitative analysis of the VTA during clinical neurostimulation.

Cochlear implants: current designs and future possibilities.
TL;DR: An overview of contemporary cochlear implants from the perspective of two designers of implant systems, which includes the anatomical situation presented by the deaf cochlea and how the different parts of an implant system must work together to produce the best results.

Trends in Cochlear Implants
TL;DR: A future landscape in amplification is presented that requires a unique, yet complementary, contribution from hearing aids, middle ear implants, and cochlear implants to achieve a total solution to the entire spectrum of hearing loss treatment and management.

Benefits of bilateral cochlear implants and/or hearing aids in children
TL;DR: Functional benefits from bilateral stimulation in 20 children ages 4–14 show that both groups perform similarly when speech reception thresholds are evaluated, but there appears to be benefit from wearing two devices compared with a single device that is significantly greater in the group with two CI than in the bimodal group.

Spatial hearing and speech intelligibility in bilateral cochlear implant users.
TL;DR: During the early stages of bilateral hearing through cochlear implants in postlingually deafened adults, there is an early emergence of spatial hearing skills, suggesting that directional hearing might emerge in a two-step process beginning with discrimination and converging on more fine-grained localization.

Speech perception, localization, and lateralization with bilateral cochlear implants
TL;DR: Five bilateral cochlear implant users were tested for their localization abilities and speech understanding in noise, and participated in lateralization tasks to assess the impact of variations in interaural time delays (ITDs) and Interaural level differences (ILDs) for electrical pulse trains under direct computer control.

Speech understanding in quiet and noise in bilateral users of the MED-EL COMBI 40/40+ cochlear implant system.
TL;DR: Bilateral cochlear implantation provides a significant benefit in speech understanding in both quiet and noise, and differences in average scores were significant at the 5% level.

Cochlear Implants: Some Likely Next Steps*
TL;DR: Some likely possibilities for further improvement are described, including combined electric and acoustic stimulation of the auditory system for patients with significant residual hearing, use of bilateral implants, and applications of knowledge about factors that are correlated with outcomes to help patients presently at the low end of the performance scale.

TL;DR: Binaural cochlear implants can assist in the localization of sounds and have the potential in some individuals to improve speech understanding in quiet and in noise.

Sound-direction identification, interaural time delay discrimination, and speech intelligibility advantages in noise for a bilateral cochlear implant user.
TL;DR: Results show that even if interaural time delay cues are not well coded or perceived, bilateral implants can offer important advantages, both for speech in noise as well as for sound-direction identification.
