| diffuse ganglion cell | Bunt (Bunt) | The diffuse ganglion cells (i.e., those whose dendrites did not show stratification, but rather ramified at all levels of the inner plexiform layer) were the most frequently impregnated in this study. The cells were characterized by somata 12-21 micrometers in
diameter and one or several relatively thin apical dendrites which branched and ramified throughout the inner plexiform layer. The branches had a very delicate, often beaded appearance, with occasional spines. Some had relatively small, circumscribed
dendritic fields (84-132 micrometers) (Fig. 1) and others had more complexly branched, wider fields extending from 160 to 360 micrometers in diameter (Figs. 2-4). | partially corresponds | | It appears...that only the diffuse ganglion cells with small dendritic fileds would correspond to the 'tight' class of Brown. | Bunt A.H. | Mihail Bota |

| retinal ganglion cell Class I | Dreher (Dreher) | HRP-labelled Class I cells, like Type I cells identified by Perry [1979] in Golgi-stained wholemounts of rat retina...have 3-7 fairly large-gauge primary dendrites, each of which bifurcates at least once, with the initial branches being about half the width of the parent dendrite. Their dendritic trees, irrespective of the location of the cell body, tend to be large (up to 470 micrometers in diameter). Class I cells are labelled after HRP injections restricted to the contralateral DLG or SC. | different | | Although Perry considered that his Type I ganglion cells could be equated with the 'loose' cells distinguished by Brown [1965] in methylene-blue stained retinal wholemontsm we feel that our Class I cells do not correspond with either of Brown's 'loose' or 'tight' classes. | Dreher B., Sefton A.J., Ni S.Y.K, Nisbett G. | Mihail Bota |
|
| retinal ganglion cell type II | Perry (Perry) | Type II cells have intermediate cell bodies and usually have smaller dendritic fields thant either type I and type III cells (see table 1). The number of primary dendrites varies from 1 to 4 in number and these pass into the outer layers of the inner plexiform layers. The cells have many short branches along the primary dendrites and the dendrites may be spiny (plate 2, figures 4, 5 and 6; and figure 9). | partially corresponds | | Type II cells are similar in form to those described by Brown (1965) as 'tight'. He described the dendritic fields of 'tight' cells as being smaller than the loose cells and having dendrites passing into the outer part of the inner plexiform layer.
