Hearing prosthesis

A method, comprising:

• delivering one or more electrical stimulation signals to a sensory organ of a recipient of a medical device to evoke perception, by the recipient, of one or more input signals;
• delivering one or more electrical stimulation signals to a vagus nerve of the recipient;
• and
• controlling delivery of the one or more electrical stimulation signals to the vagus nerve of the recipient to enhance perception of the one or more input signals by the recipient.

A medical device, comprising:

• an internal receiver/transceiver unit;
• a stimulator unit;
• a first electrode in communication with the stimulator unit, and configured to deliver electrical stimulation to auditory nerve cells in a recipient's cochlea, and
• a second electrode in communication with the stimulator unit, and configured to come in contact with, and to deliver electrical stimulation to vagus nerve of the recipient.

A medical device, comprising:

• a stimulator unit configured to:
• generate one or more first electrical stimulation signals based on one or more input signals, and
• generate one or more supplemental electrical stimulation signals;
• and
• one or more electrodes configured to deliver the one or more first electrical stimulation signals to a sensory organ of a recipient of the medical device to evoke perception, by the recipient, of the one or more input signals;
• at least one electrode configured to deliver the one or more supplemental electrical stimulation signals to a vagus nerve of the recipient;
• and
• a processing unit configured to synchronize delivery of the one or more supplemental electrical stimulation signals to the vagus nerve of the recipient with delivery of the one or more first electrical stimulation signals to the sensory organ to enhance perception of the or more input signals by the recipient.
