Summary
Basically, in this study the cochlear implants restored hearing to the deaf participants by stimulating the auditory nerve with about sixteen electrodes. Cochlear patients must work hard to hear, mainly because their sound signal is usually deteriorated. After the procedure the patients take a while to get accustomed to their new hearing devices. Ultimately, they become good at hearing speech and their visual cortex is activated with sound. Link to the actual article by Giraud et al.
