Schematic illustration of the bipolar cell types identified in the enhancer trap lines. The sublayers (s1–6) within sublamina a (OFF) and b (ON) of the IPL are indicated, and the basal-apical orientation is shown with basal at the bottom. Cell bodies are shown as filled circles and their relative positions within the INL are indicated. The axon terminal structures are shown as filled boxes.
