How many electrodes are in Cochlear implants?

The number of electrodes in cochlear implants can vary depending on the specific implant model and manufacturer. Generally, modern cochlear implants have an array of electrodes ranging from 12 to 24.

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.
