Abstract

Embodiments are generally directed to improving the interface between one or more electrode contacts of a medical implant and the neurons of a recipient of the medical implant. In an embodiment, a growth factor is applied to stimulate the growth of peripheral processes (also referred to as dendrites). Then an electric field is applied to direct the growth of the peripheral processes towards the electrode contact. Growing peripheral processes towards the electrode contacts may reduce the charge required to stimulate the peripheral processes and improve operation of the medical implant.
