Dorsal and ventral surface of the multi-electrode array implant and zoomed in view of the electrodes. A) Ventral view of the implant system: external omnetics connector that is secured to the skull (headplug connector), Teflon coated stainless steel wires from the connector to the circuit board (control wires), electrode array, EMG wires, and ground wires. B) Dorsal surface of the implant. C) Zoomed in view of the multi-electrode array: note the plantinum electrodes, platinum traces, and the holes used to thread the array during implantation. D) Zoomed in view of a single electrode along with the platinum traces. Note the grid-like pattern formed by the parylene on the electrode used to prevent delamination. E) Expanded view of the parylene-based array with platinum electrodes.
