Electron microscopy of Golgi preparations of goldfish retina shows that dendrites of type a (hyperpolarizing, off-center) bipolar cells make wide cleft junctions unassociated with synoptic ribbons, while those of type b (depolarizing, oncenter) bipolar cells make narrow cleft junctions and synoptic ribbon contacts, with rods and cones. This suggests that wide cleft junctions are the site of sign-conserving, and narrow cleft junctions or ribbon contacts (or both) are the site of signinverting synoptic transmission from photoreceptors to bipolars.
