When an additional bipolar type which stratifies slightly more vitread and is calbindin negative was detected, this cell was renamed diffuse bipolar 3a cell. The axons of neighboring DB3a cells make homologous gap junctions. The DB3a cells provide the majority of their output to OFF parasol cells. An OFF calbindin-positive bipolar cell that has a large dendritic field and stratifies narrowly close to the middle of the inner plexiform layer. Its axon terminal is characterized by regularly branching and varicose processes resembling beads on a string. Most of DB3a contacts with cones are triad-associated.
