Objective: (1) To survey the use of bimodal stimulation by prelingually deaf children receiving unilateral cochlear implantation and (2) to investigate demographic and audiologic factors explaining the use of bimodal stimulation.
Study Design: Cross-sectional survey.
Setting: Tertiary care institution.
Subjects And Methods: The study included 44 unilaterally implanted prelingually deaf children from a single institution, with a minimum follow-up of 1 year. During routine follow-up visits, an examiner interviewed parents on their children's use of bimodal stimulation. At the same time, residual hearing and hearing aid gain in the contralateral ear were assessed.
Results: Approximately half of patients (52%) used bimodal stimulation. On average, bimodal users showed better mean unaided and aided thresholds than nonbimodal users (P < .001). A mean 250- to 500-Hz unaided threshold ≤90 dB HL in the contralateral, nonimplanted ear was associated with a higher probability of bimodal use (P = .008). Parental satisfaction with the contralateral hearing aid was inversely correlated with mean 125- to 500-Hz and 1000- to 4000-Hz unaided thresholds (P < .001) and mean 250- to 500-Hz and 1000- to 4000-Hz aided thresholds (P < .001).
Conclusions: A mean 250- to 500-Hz unaided threshold ≤90 dB HL is associated with a higher probability of bimodal use by prelingually deaf children. Better residual hearing is associated with a higher degree of parental satisfaction with the contralateral hearing aid. This information could be useful to counsel parents of prelingually deaf children, when deciding between bimodal stimulation and simultaneous bilateral cochlear implantation.

Article Synopsis
- ctACS may offer a non-invasive treatment avenue for psychiatric and neurological disorders, but its effectiveness is limited by a lack of understanding of its impact on cerebellar activity at cellular levels.
- Previous research indicated that AC stimulation influenced Purkinje cell (PC) and cerebellar nuclear (CN) cell activity in a frequency-dependent manner when applied to the cerebellum.
- This study found that ctACS altered PC and CN activity in rats, revealing that the modulation patterns varied with stimulus frequency and electrode placement, indicating potential for targeted treatment strategies.

Working memory (WM) reflects the transient maintenance of information in the absence of external input, which can be attained via multiple senses separately or simultaneously. Pertaining to WM, the prevailing literature suggests the dominance of vision over other sensory systems. However, this imbalance may be stemming from challenges in finding comparable stimuli across modalities.

Background: Cochlear implants (CIs) have the potential to facilitate auditory restoration in deaf children and contribute to the maturation of the auditory cortex. The type of CI may impact hearing rehabilitation in children with CI. We aimed to study central auditory processing activation patterns during speech perception in Mandarin-speaking pediatric CI recipients with different device characteristics.

In perceptual studies, musicality and pitch aptitude have been implicated in tone learning, while vocabulary size has been implicated in distributional (segment) learning. Moreover, working memory plays a role in the overnight consolidation of explicit-declarative L2 learning. This study examines how these factors uniquely account for individual differences in the distributional learning and consolidation of an L2 tone contrast, where learners are tonal language speakers, and the training is implicit.

Background: A recent study highlighted variability in complication rates among polylactic acid (PLA)-based collagen stimulator fillers, with notably high rate of complications linked to PLLA-Elleva. The study suggested that product-specific characteristics might have greater impact on outcomes than injection techniques.
Methods/results: Through a critical analysis of pertinent literature, this commentary explores how PLLA-Elleva's unique physicochemical properties, particularly its bimodal degradation process, may contribute to the increased nodule formation observed.
