Star-shaped cells of the amacrine cell layer

Using silver impregnation techniques and light microscopy we have described a new type of interneuron in the adult chicken retina. These cells are located in the innermost level of the INL. Expansions arise from the basal portion of the perikaryon and ascend from there, ending in the inner third of the INL. Other expansions extend through the three first sublayers of the IPL. We compared the morphological differences shown by these cells in relation to the amacrine cells and interplexiform cells, all of which are situated on the same stratum.
