When mapped with a small spot of light, the central receptive fields of bipolar cells in the salamander retina are much larger than the extent of bipolar cell dendrites. Furthermore responses of bipolar cells to distant spots of light are considerably delayed relative to proximal spots. Using quanti
## Abstract The synaptic organizations of Ξ³βaminobutyric acidβimmunoreactive (GABAβIR, GABAergic) and nonβGABAβIR (nonβIR, glutamatergic) bipolar cells in salamander retina were compared by postembedding immunoelectron microscopy. A total of 238 presynaptic bipolar cell synapses were studied; 61 we
