Electrode Spanning with Partial Tripolar Stimulation Mode in Cochlear Implants

Cochlear-implant spatial selectivity with monopolar, bipolar and tripolar stimulation.

Sharp spatial selectivity is critical to auditory performance, particularly in pitch-related tasks. Most contemporary cochlear implants have employed monopolar stimulation that produces broad electric fields, which presumably contribute to poor pitch and pitch-related performance by implant users. Bipolar or tripolar stimulation can generate focused electric fields but requires higher current t...

Speech Perception in Children with Cochlear Implants

Cochlear implants provide access to the speech signal in children with hearing loss that often cannot benefit from acoustic hearing aids. However, despite the numerous positive results in pediatric cochlear implantation, published data still indicated a wide range of performance among implant recipients. Hence, a need to study the possible variables that can affect performance, could account fo...

Binaural release from masking with single- and multi-electrode stimulation in children with cochlear implants.

Cochlear implants (CIs) provide children with access to speech information from a young age. Despite bilateral cochlear implantation becoming common, use of spatial cues in free field is smaller than in normal-hearing children. Clinically fit CIs are not synchronized across the ears; thus binaural experiments must utilize research processors that can control binaural cues with precision. Resear...

Identifying Impaired Cochlear Implant Channels by Using the Partial- Tripolar Configuration: Implications for Cochlear Implant Fittings

Emotional Perception of Music in Children with Unilateral Cochlear Implants

Introduction: Cochlear implantation (CI) improves language skills among children with hearing loss. However, children with CIs still fall short of fulfilling some other needs, including musical perception. This is often attributed to the biological, technological, and acoustic limitations of CIs. Emotions play a key role in the understanding and enjoyment of music. The present study aimed to in...
