Cone pedicles are labeled by serial numbers and accordingly in the following figures. The cellular contours are shown with continuous lines for innervated cones and dotted lines for non-innervated cones. M/L-cone contours are colored gray and S-cone contours blue.In Figure 5, 12 M/L-cones and six S-cones shown in gray have been employed for evaluation of cone divergence, determined by identifying all companion bipolar cells LGK974 site together together with the quantity of output title= 2042098614560730 synaptic contacts. We investigated all ON bipolar dendrites surrounding these target cones. The divergence patterns differed tremendously among M/L- and S-cones (Table 2, Figures 6D,E). The M/L-cone directed virtually half of all output synapses (26) to IMB cells and allocated the other half to four non-IMB cells in decreasing order DB4 (14) > DB5 (10) > DB6 (2) > GB (0.five). In contrast, the S-cones directed nearly all outputs (40) title= s12936-015-0787-z to BB cells and sporadically title= acr.22433 allocated the few remaining contacts (1) to 4 other ON bipolar varieties. Therefore, the mean variety of DB and GBcells per S-cone and also the imply variety of contacts innervating on these DB or GB cells per S-cone were each at most 0.five (Table 2). Figure 6F shows the divergence of output in the representative M/L-cone and S-cone to their ON and OFF routes by means of three positional classes of contacts.Lls was TA (58 ), and for GB cells was NTA (46 ) (Figures 5, 6C). These distinctive ON bipolar cells also displayed distinct connectivity patterns to M/L- and S-cones, suggesting typespecific differences in chromaticity. IMB cells contacted only M/L-cones and BB cells contacted only S-cones. Therefore, the M/L-cone-IMB pathway along with the S-cone-BB pathway appear structurally independent. Other DB and GB cells almost exclusively contacted M/L-cones and only hardly ever contacted Scones. Only among six DB4 cells connected to one S-cone with a single make contact with, two of 7 DB5 cells connected to two S-cones with a single get in touch with and two contacts, respectively, two of five DB6 cells connected to two S-cones each and every with one particular speak to, and among two GB cells connected to 1 S-cone with two contacts. As a result, the mean number of contacts with S-cones per bipolar cell (Table 1) was at most one. On top of that, these S-cone contacts with DB and GB cells were always positioned at non-invaginating positions (TA or NTA).Frontiers in Neuroanatomy | www.frontiersin.orgOctober 2016 | Volume 10 | ArticleTsukamoto and OmiMacaque ON Bipolar Cell ConnectivityFIGURE 3 | ON-OFF lateral amacrine cell in contact with DB2 and DB4 cells.
