From: Development of very large electrode arrays for epiretinal stimulation (VLARS)
Functional testing of a star type VLARS MEA. For recording of spontaneous and evoked spike activity a piece of the retina (arrow) from a Wistar rat was placed with the ganglion cell layer onto the VLARS-MEA. The bond pads on the right are connected to the MEA hardware equipment for recording and stimulation. The wires connect each of 25 active VLARS electrodes with the bond pads.
