unistratified retinal ganglion cellLeure-Dupree (LD)

The ganglion cells observed were of the unistratified type (Polyak, '41); their dendrites did not extend deep into the inner plexiform layer (figs. 19, 20). They were situated close to one another, and therefore, considerable overlapping of the dendritic trees may occur. The range of the dendritic trees of 25 ganglion cells as 20-106.6 micrometers.partial correspondence
The ganglion cell described here may be the "loose" type (Brown, '65).Leure-Dupree A.E.Mihail Bota
giant ganglion cellBunt (Bunt)

Several examples have been found of giant cells similar to those described by Polyak in the primate retina as having large somata (20 micrometers or greater) and relatively thick dendritic branches which were smooth and spine-free, radiating outward from the soma to extend throughout the inner plexiform layer. The diameter of the dendritic spread reached 260 micrometers.partially corresponds
It appears that most of these cells correspond to the 'loose' type found by Brown in methylene blue-stained...Bunt A.H.Mihail Bota
unistratified ganglion cellBunt (Bunt)

A class of relatively large ganglion cells (soma diameter 17-22 micrometers) was characterized by several relatively thick apical dendrites whose branches were smooth in appearance, with only occasional knobs and spines, and appeared to ramify in two planes, in the outer one-third and middle one-third of the inner plexiform layer, with a gap in between (Fig. 10). The dendritic fields varied from 132 to 220 micrometers in diameter.partially corresponds

retinal ganglion cell Class IDreher (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 IPerry (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.partially corresponds
The type I cells have a similar dendritic morphology to the 'loose' type of ganglion cell described by Brown (1965) in the rat retina. Brown, however, described these cells as having dendrites which terminate in the inner part of the inner plexiform layer, but the type I dendrites terminate in the outer layers of the inner plexiform layer, so the correspondence is not altogether clear.Perry V.H.Mihail Bota
retinal ganglion cell type IIIPerry (Perry)

Type III cells have small bodies but they have the largest range of dendritic field sizes (see table 1). The dendrites of this cell class branch less frequently than those of the other classes. This group of cells encompasses a slightly wider variety of dendritic morphology, than the other three classes.partially corresponds
...type III cells clearly correspond to some of the 'loose' ganglion cells described by Brown (1965)...Perry V.H.Mihail Bota
