| outer alpha retinal ganglion cell | Tauchi (Tauchi) | The cell illustrated at the left side of Fig. 2A had a somewhat smaller, oval or spherical soma and revelead dendrites arborizing at a levels more distal than that of inner cells, in the outer lamina of the IPL (sublamina a). Despite their spherical soma, their dendritic branchings are still characteristic of alpha cells. We therefore call these cells outer alpha cells. | identical | | In accordance with previous findings by Peichl (1989) we have shown in the rat retina that inner and outer alpha cells are systematically different in soma shape and size as well as in the manner of dendritic branching. | Tauchi M., Morigiwa K. & Fukuda Y. | Mihail Bota |

| retinal ganglion cell A2 outer | Huxlin and Goodchild (HG) | Alpha ganglion cells, which were defined by Peichl (1989), were identified and termed RGA2 in the present study (see Table 1). The RGA2 cell has a large soma from which a thick axon emerges. Four to eight stout primary dendrites project radially from the cell body and branch repeatedly in a Y-shaped pattern. The dendrites branch at regular intervals, with the first branch point being within half of a soma diameter of the cell body. This branching pattern gives the appearance of a relatively uniform, medium density of dendrites across the dendritic arbor. The cell body is usually situated at the centre of the dendritic field. They stratify at ... 34 ± 10% of the IPL (outer)... | synonim | | Alpha ganglion cells, which were identified by Peichl (1989), were identified and are termed RGA2 in the present study (see Table 1). | Huxlin K.R & Goodchild A.K. | Mihail Bota |

| retinal ganglion cell type I | Perry (Perry) | Type I cells have the largest cell bodies of all the classes (see table 1). The primary dendrites are generally smooth in appearance but sometimes have dendritic spines, and roughly halve their diameter at the first bifurcation (see plates 1, figures 1 and 2). The cells have 3 to 6 primary dendrites which enter the inner plexiform layer diagonally and appear to terminate in the outer part of inner plexiform layer. On many of these cells an axon could be identified and the axons were in general the thickest observed. | is included | | The present analysis of rat ganglion cells with large somata defined two classes of cell within Perry's ('79) type I category named alpha and delta cells. Collator note: retinal alpha and delta cells are further divided in inner- and outer- retinal ganglion cells. | Peichl L. | Mihail Bota |
