Identification of RGCs using the high-density multi transistor array.

<p>(A) Four consecutive electrical images acquired every 100 µsec reveal the occurrence and propagation of action potentials along the proximal axon. The electrical images were obtained after calculating the spike triggered average over more than thirty spikes. Visualization of the axon identifies a ganglion cell (Methods). Scale bar: 200 µm. (B) Typical light responses of four RGCs in wild-type retinas. The histograms were calculated for repeated stimulus presentations. (binsize: 5 ms).
