| inner alpha retinal ganglion cell | Tauchi (Tauchi) | Figure 2A depicts photomicrograph of dendritic morphologies of a pair of Lucifer-injected large ganglion cells. The right hand cell has a polygonal soma like the ones shown in Fig. 1, and a morphology typical of alpha cells in having 5-6 primary dendrites which branch out out simmetrically, together with a thick axon (Boycott and Wassle 1974; Amthor et al. 1983; Peichl et al. 1987a and 1987b). Similarly, most of the dye-injected cells having a large polygonal soma more than 20 micrometers in diameter were identified as typical alpha cells. The dendrites of all these cells were found ramifying in the inner part of the IPL, namely in sublamina b. We will therefore refer to them as inner alpha cells (Peichl 1989). | identical | | Figure 2A depicts photomicrograph of dendritic morphologies of a pair of Lucifer-injected large ganglion cells.

| retinal ganglion cell A2 inner | 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 ... 72 ± 15% of the IPL (inner)... | 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 |
