Retina Implant

Epiretinal contacts for retinal degeneration

One of the applications of arrays of microelectrodes is the retinal implant. Here's an example of an acute test of electrical stimulation of a rabbit's eye, using a microelectrode array positioned on the retinal surface (ganglion cell layer).  We stimulate with different currents, in order to evaluate the "brain's response" (EEP amplitude and latency).
