Cochlear implant artifact removal

When an auditory stimulus is presented to the subject the cochlear implant generates electromagnetic wave which covers the ERP's up to 500 mSec post-stimulus presentation. innovative algorithm to remove the cochlear implant artifact enables ERP waves analysis.

Ex.1 Average ERP response

An average ERP response recorded from Cochlear Implanted patient evaluated without using the special cochlear implant artifact rejection algorithm (red line) and the same ERP's after the implementation of the special algorithm (blue line).
