IAC 9769

IAC 9769 is a wide-field pure feedforward GABAergic interstitial amacrine cell (IAC). This is the first pure feedforward GABAergic AC discovered. IAC 9769.

  • collects excitation exclusively from ON (CBb) bipolar cells (BCs)
  • provides inhibitory feedforward different of ON ganglion cell (GC) classes
  • engages in nested feedforward to other classes of GABAergic ACs
  • is coupled to different classes of GABA+ GCs (e.g. GC 606 at 2 sites)
  • is coupled tip-to-tip to other ACs resembling IACs.

AII AC 476

AII AC 476 is a narrow-field rod BC-driven glycinergic amacrine cell (AC). AII ACs are the fundamental rod → cone crossover elements of the retina AII ACs

  • collect excitation from rod BCs
  • are coupled to all CBb cells
  • are presynaptic and postsynaptic to all CBa cells
  • are heavily coupled in an AII :: AII network
  • provide crossover feedforward inhibition to ON α and δ GCs
  • are postsynaptic to many GABA+ AC classes
  • are presynaptic to specific OFF GABA+ ACs that engage in cone → rod crossover

Four rendered AII ACs superimposed on RC1 slice 001. Also shown are numerous other AII ACs located at their XY positions in the volume. Most are not visible in Slice 001, being positioned deeper in the volume.
