1. A method comprising:
- delivering, with a first set of electrodes of a cochlear implant, an electrical signal to a cochlea of a recipient of the cochlear implant, wherein the cochlear implant comprises a plurality of electrodes, and wherein at least a portion of the plurality of electrodes are positioned within the cochlea of the recipient to stimulate an auditory nerve of the recipient;
measuring, with a second set of electrodes of the cochlear implant, a response to the electrical signal; and
based on the measured response, determining that the electrical signal directly and electrically stimulated a facial nerve of the recipient.

Abstract
The present application discloses systems and methods for detecting non-auditory nerve stimulation with an implant having a plurality of electrodes configured to electrically stimulate a target nerve of the implant recipient. One embodiment includes generating an electrical stimulation signal with a first set of electrodes of the implant, measuring a response to the electrical stimulation signal with a second set of electrodes of the implant, and determining whether the electrical stimulation signal stimulated at least one non-target nerve of the implant recipient based on the measured response.

14. A cochlear implant comprising:
-
a plurality of electrodes including (i) a first set of electrodes configured to deliver at least one electrical signal to a cochlea of recipient of the cochlear implant to stimulate the recipient'"'"'s auditory nerve, and (ii) a second set of electrodes configured to measure a response to delivery of the at least one electrical signal to the cochlea; and circuitry configured to analyze the measured response and determine, based on the analysis, that the at least one electrical signal directly and electrically stimulated a facial nerve of the recipient. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A system comprising:
- a computing device configured to communicate with a cochlear implant, wherein the computing device is configured to;
receive, from the cochlear implant, a measured response to an electrical signal applied via a first set of electrodes of the cochlear implant, wherein the electrical signal is applied to stimulate a recipient'"'"'s auditory nerve and wherein the measured response is measured via a second set of electrodes of the cochlear implant; and
analyze the measured response and determine that the measured response includes an indication that the electrical signal directly and electrically stimulated a facial nerve of the implant recipient. - View Dependent Claims (22, 23, 24, 25, 26)
