  • ~17 synapses to same ~10 Invaginating Midget Bipolars
    • Short/Blue Bipolar
      • 1 or 2 cells via a conventional chemical synapse
    • Small Invaginating Bipolar

  • ~6 synapses to ~10 Off Midget Ganglion Cells
    • which are associated with the input Midget Bipolars

• Function
  • Since the input is achromatic, then the response must be as well. They are thought to contribute to the inhibitory surrounds of the midget(P) ganglion cells.

• Morphology

  • Connects with every midget bipolar within reach
