S-cone with one get in touch with, two of 7 DB5 cells connected to two S-cones with one particular contact and two contacts, respectively, two of 5 DB6 cells connected to two S-cones each with 1 make contact with, and among 2 GB cells connected to one S-cone with two contacts. Thus, the M/L-cone-IMB pathway along with the S-cone-BB pathway seem structurally independent. Other DB and GB cells just about exclusively contacted M/L-cones and only hardly ever contacted Scones. Only among 6 DB4 cells connected to 1 S-cone with a single contact, two of 7 DB5 cells connected to two S-cones with 1 get in touch with and two contacts, respectively, two of five DB6 cells connected to two S-cones every single with one particular make contact with, and one of 2 GB cells connected to 1 S-cone with two contacts. Thus, the imply variety of contacts with S-cones per bipolar cell (Table 1) was at most one. Moreover, these S-cone contacts with DB and GB cells have been always positioned at non-invaginating positions (TA or NTA).Frontiers in Neuroanatomy | www.frontiersin.orgOctober 2016 | Volume ten | ArticleTsukamoto and OmiMacaque ON Bipolar Cell ConnectivityFIGURE three | ON-OFF lateral amacrine cell in get in touch with with DB2 and DB4 cells. Distribution in the postsynaptic web pages of the ON-OFF lateral amacrine cell in get in touch with together with the ribbon-associated presynaptic websites of DB2 and DB4 cells is displayed in top rated view (A) and side view (B). The contacts with DB2 (206 contacts labeled with light blue rectangles) are confined to strata 1 and 2 of IPL even though those with DB4 (25 yellow rectangles) are confined to stratum three. (C) Traditional input synapses (125 green circles) from other amacrine cells. (D) Output synapses (178 orange triangles) are largely reciprocally directed to DB2 (146 contacts) and DB4 (24 contacts) cells and less generally to other cells.

Cone pedicles are labeled by serial numbers and accordingly inside 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 five, 12 M/L-cones and 6 S-cones shown in gray were utilized for evaluation of cone divergence, determined by identifying all companion bipolar cells together using the variety of output title= 2042098614560730 synaptic contacts. We investigated all ON bipolar dendrites surrounding these target cones. The divergence patterns differed greatly in between M/L- and S-cones (Table two, Figures 6D,E). The M/L-cone directed virtually half of all output synapses (26) to IMB cells and allocated the other half to 4 non-IMB cells in decreasing order DB4 (14) > DB5 (ten) > DB6 (two) > GB (0.five).
