In present paper the properties of the pseudo polarograms of Arsenic at a gold electrode are stud - ied.

To investigate the relatively safe area of implanting vision prosthesis microelectrode to optic nerve, and to provide anatomic data for operations of optic nerve.

All visual prostheses have the same function: converting outside optical signal to certain current pulses and stimulating the relevant parts by the micro-electrode array to generated phosphenes.
