Abstract

We report in-vitro multisite field potential recordings from fish retina using a vertically integrated silicon (Si) microprobe array. Eight active channels of the enlarged probe-head ldquoKokeshi (Japanese dolls)rdquo type Si probe enabled multisite electrical recordings of retinal responses (electroretinograms (ERGs)) to white light stimuli. The ERG a- and b-waves were obtained at each probe, and the result suggests the capability of the Si probe array for use in further investigations of spatio-temporal property of ERGs.
