Individual types of retinal neurons are distributed across the retina as regular arrays of cells, commonly referred to as “retinal mosaics” (Wassle and Riemann, 1978). This regularity in their patterning is generally assumed to ensure that all locations across the retina are sub-served by every type of retinal neuron, each participating in their own unique way to the local computations carried out before transmission of the visual signal to higher visual centers in the brain. The extent to which each retinal cell type evidences spatial order varies, with some mosaics being only slightly more regular than random distributions of cells (Reese, 2008a). With the exception of certain photoreceptor mosaics however (particularly in non-mammalian retinas), the spatial order present within the more regular of these mosaics lacks any higher-order lattice-like patterning (Cook, 2003), and simulations based on local-spacing rules that minimize proximity between immediate homotypic neighbors are sufficient to account for the spatial order present (Eglen, 2006). Indeed, the order present within a mosaic is generally independent of that in other mosaics (Rockhill et al., 2000), suggesting that the composition of retinal clones and the spatial relationships between them cannot account for the patterning in these mosaics. Rather, cells within a mosaic are free to move tangentially as they space themselves out, establishing territories surrounding each cell where the probability of a homotypic cell is lower than at further distances from the cell (Reese and Galli-Resta, 2002).
