Objectives: To evaluate sound localization ability in patients with unilateral cochlear implant, who do not wear a hearing aid on the contralateral ear, and to try to improve this ability by training.
Setting: Tertiary academic referral center.
Methods: In the initial test, patients were exposed to sound stimuli from different directions and were asked to localize them. Following a training period the patients were re-evaluated by the same test. For each test, the percentage of correct answers and the final test score were calculated.
Results: In the initial test, the mean score of the study group of four cochlear implant users was 42.8 (out of a maximal score of 100), the mean rate of correct responses was 27.5%. Following a training period (6.5 sessions on the average), on the final test the mean score of the group was 74.3, while the mean rate of correct responses was 66.5%.
Conclusions: The results demonstrated that patients with unilateral cochlear implant have some ability to localize sound, and that this ability may be improved by regular training.

Purpose: Cochlear implantation (CI) surgery is essential for restoring hearing in individuals with severe sensorineural hearing loss. Accurate placement of the electrode within the cochlea is essential for successful auditory outcomes and minimizing complications. This study aims to analyze the relationship between the round window niche (RWN) alignment, its visibility during surgery, and the impact on surgical techniques and outcomes.

Objective: This review aims to analyse the implications of the World Health Organization's 2021 world report on hearing, with a particular focus on the cochlear implant field. The objective is to understand the challenges and opportunities highlighted in the report and propose viable solutions for effective implementation within the cochlear implant community.
Methods: Following the release of the World Health Organization's world report on hearing, cochlear implant professionals explored and discussed the implications of the report with examples from various countries to understand the disparities in access, reimbursement policies, and social stigma associated with hearing loss.

Objectives: This study examined the relationships between electrophysiological measures of the electrically evoked auditory brainstem response (EABR) with speech perception measured in quiet after cochlear implantation (CI) to identify the ability of EABR to predict postoperative CI outcomes.
Methods: Thirty-four patients with congenital prelingual hearing loss, implanted with the same manufacturer's CI, were recruited. In each participant, the EABR was evoked at apical, middle, and basal electrode locations.

Background: Mild Behavioral Impairment (MBI) is a condition characterized by neuropsychiatric symptoms (NPS) in older adults without dementia, serving as a precursor to various forms of dementia. This study explores the association between NPS and functional connectivity (FC) within the default mode network (DMN), executive control network (ECN), and salience network (SN) across three high-risk cohorts: mild cognitive impairment (due to Alzheimer's) (MCI, n = 79), cerebrovascular disease (CVD, n = 144), and Parkinson's disease (PD, n = 132).
Method: A total of 367 participants were recruited from the Ontario Neurodegenerative Disease Research Initiative (ONDRI).
