abstract = {Simultaneous stimulation and recording of retinal nerve
cells with penetrating three dimensional multi-electrode
arrays on a localized area is a demanding challenge in next
generation retina implant research. Within the scope of this
research we developed a device to stimulate a network of
bi-polar cells and record retinal ganglion cells with a
slight time gap to overcome long recording dead times and
switching artifacts in common stimulation- and recording
systems. The device contains a four channel stimulator
capable of pushing arbitrary bi-polar charges into the
tissue and a 16 channel commercial electrophysiology
interface chip. The device is a miniaturized front-end for
our former developed embedded wireless communicating sensor
node. First tests in in-vitro retina slices from adult rat
with our device show reliable recordings of ganglia cell
activity below 1ms after the bi-polar cell stimulation.},
