All the synapses where DB3 bipolar cells were presynaptic had two postsynaptic elements. Approximately half had one amacrine cell process and one ganglion cell dendrite. Dyads with two identified ganglion cell dendrites were uncommon, but some of the small, unidentified postsynaptic elements may have been dendritic spines of ganglion cells.
