人工内耳にはいくつの電極がありますか？
Each electrode is individually placed within the spiral-shaped cochlea (the inner ear) to stimulate different regions of the auditory nerve. More electrodes often correspond to finer pitch discrimination and better sound quality as it provides more points of stimulation along the frequency range of human hearing. However, electrode count alone does not determine overall device performance and outcomes, as other factors such as electrode design, signal processing strategies, and individual user experiences also play key roles in implant success.
