Furthermore, different populations of Isl1-containing cells located in the inner nuclear layer (INL) could be distinguished by both morphological and topographical features: (i) a small population of cells with the major axis oriented parallel to the vitreal surface, lying at the border between the outer plexiform layer (OPL) and the INL, in the horizontal cell layer (Figures 2(b) and 2(c)); (ii) a population of cells located in the middle of the INL, in the bipolar cell layer (Figures 2(b), 2(c), 2(e), 2(f), 2(h), and 2(i)); and (iii) a small population of cells located at the inner edge of the INL, in the region where the amacrine cells
are normally found (Figures 2(b), 2(c), 2(e), 2(f), 2(h), and 2(i)).

Since in the highest density areas of avian retinas (Bravo & Pettigrew) the RGCs become smaller and distributed into multiple sublayers, as also reported previously (Coli et al.), the authors refer to the study of RGCs density by radial retinal sections to also identify the deeper RGCs and to distinguish them from the displaced amacrine cells

The other is lateral interaction pathway, comprising local feedback circuits from horizontal cells back to photoreceptors and from amacrine cells
back to bipolar cells.
The intervening layers incorporate several types of cell with large dendritic arbors, divided into horizontal cells that control for different illumination conditions and feedback to the receptor and bipolar cells and amacrine cells
that feed into the center-surround organization of the Retinal Ganglion Cells.
For example, it is known that the amacrine cells
of the retina, which are presynaptic of the ganglion cells, fire independently.
They note: "Deletion of GSK3ss resulted in ss-catenin stabilization and MG proliferation without retinal injury," and that, "Intriguingly, after gene transfer of ss-catenin or Lin28, a subset of cell-cycle-reactivated MGs express markers for amacrine cells
, a type of retinal interneurons."
