The retina houses a multitude of amacrine cell types, which display the highest diversity in morphology, transmitter repertory and putative function of all retinal neurons. So far, only few of these cell types have been thoroughly investigated, because in many cases a low population density impedes the systematic study. This is notably true for wide-field amacrine cells, which are characterized by their far-reaching cellular processes and are thought to mediate long-range lateral inhibition at the retinal output stage. By using retinas expressing fluorescent markers in only a subset of neurons we target the identification of specific wide-field amacrine cell types for studying their morphology, circuitry and physiology.
