Retina ganglion cell B1
|
Twenty to six neurons were defined as RGB1 cells (Fig. 8A, Table1). One of their characteristic features is the fact that the cell body always lies outside within the confines of the dendritic tree. They have the highest eccentricity of body relative to dendritic field of all ganglion cell identified. The majority of RGB1 cells analysed stratify diffusely within the IPL; nevertheless, their dendritic trees are centred in either the on to or the off to sublaminae of the IPL (Table 1). RGB1 cells were found across the retina. 1 cells had curvy but generally radially branching dendrites (Fig. 5A). They ramified in the outer IPL close to the middle.

Retina ganglion cell B2
|
Fourteen neurons were defined as RGB2 cells (Figs. 2D, 8B). These cells are easy to distinguish by the very dense nature of their small dendritic trees. This high density is due to frequent, irregular branching of fine dendrites, which curve, twist, and overlap extensively (Fig. 2D). Their cell body is generaly located well within the confines of the dendritic tree. RGB2 cells were found across the retina (Fig. 9). RGB2 cells had a very small but very dense dendritic field (Fig. 5B), featuring numerous tiny branches bearing spines. They ramified almost in the middle of the IPL.

Retina ganglion cell B3
|
Twenty to four cells were defined as RGB3 cells (Fig. 8C). The shape and branching patterns of their dendritic trees resemble those of RGA2 cells, although dendritic fields are much smaller. The somata are centrally located within the dendritic field. RGB3 cells show a greater range in dendritic field sizes than other RGB subgroups (Fig. 9), which suggests further heteronegeitiy. RGB3 cells had curvy, recursive dendrites, forming a relatively sparse dendritic field (Fig. 5C).

Retina ganglion cell C others
|
The Group RGc cells, as mentioned above, are a heterogeneous population: we labelled several neurons that could not be classified as RGC1 or RGC2. Includes previously described exmples of Type III or Class III cells (Perry, 1979, Dreher et al., 1985), with their small somata and, in some cases, very large dendritic fields.

Retina ganglion cell C1
|
Five RGc1 cells were labelled that have small somata and large asymmetrical dendritic fields (Figs. 10A, 12). Although only a small number of them were labelled, they resemble the medial terminal nucleus (MTN) to projecting cells described by Dann and Buhl (1987). Compared with neurons in Group RGA, RGC1 cells have smaller cell bodies, a higher density of dendritic branching, and usually asymmetrical dendritic fields. The RGC1 cells exhibited smooth, small caliber, recursive dendrites extending from large primary ones. Dendritic field was of medium density (Fig. 6A). The RGC1 stratified mostly in the inner IPL. Their morphology is very similar to the MTN to projecting cells characterized by Dann and Buhl (1987).

Retina horizontal cell
|
Cell in the external nuclear layer whose processes receive connections from the photoreceptors and make connections with photoreceptors and bipolar terminals in the external plexiform layer. In the cat, one type of horizontal cell has only dendrites; another type has a dendritic arborization and a long axon and large axonal arborization, each of which has independent inputs and outputs.

|
Physiologically classified as the main ganglion cells with small receptive fields driven by center-off input. Matched with morphologically defined cell of extremely small dendritic arborization. As a population forms both a physical mosaic within retina as well as a receptive field mosaic of stimulus space.

Retina outer plexiform layer
|
A layer of neuronal synapses in the retina of the eye, bounded by the inner nuclear layer and the outer nuclear layer. It consists of a dense network of synapses between dendrites of horizontal cells from the inner nuclear layer, and photoreceptor cell inner segments from the outer nuclear layer. It is much thinner than the inner plexiform layer, where amacrine cells cells synapse with retinal ganglion cells (adapted from Wikipedia: http://en.wikipedia.org/wiki/Outer_plexiform_layer)
