One particular IMB and 7 DB cells had a total of 39 invaginating contacts with P41, whereas 4 BB cells had 43 invaginating contacts with P39. Hence the invaginating contacts outnumbered the ribbonsFrontiers in Neuroanatomy | www.frontiersin.orgOctober 2016 | Volume ten | ArticleTsukamoto and OmiMacaque ON Bipolar Cell ConnectivityFIGURE 5 | Abundance of your 3 positional classes of synaptic contacts over the complete cone area for every ON bipolar cell sort. A group of ON bipolar cells of your same form shows a characteristic distribution of contacts with cone pedicles. 3 positional classes of contacts with cones are invaginating (hexagons), TA (rectangles), and NTA (ellipses). Contacts with rods are only noted for GB. Twelve pedicles (22, 28, 30, 31, 32, 36, 38, 41, 46, 47, 48, and 51) for IMB, DB, and GB, and six S-cone pedicles (15, 26, 34, 39, 94, and 118) for BB, designated in gray, are used for make contact with evaluation per cone in Figures 6D,E.Frontiers in Neuroanatomy | www.frontiersin.orgOctober 2016 | Volume 10 | ArticleTsukamoto and OmiMacaque ON Bipolar Cell ConnectivityFIGURE six | Summary of dendritic synapse measurement. (A) The number of cones converging onto every single bipolar cell (just about every cone was equally counted as unity no matter the amount of contacts). (B) The total number of contacts of your three positional classes in between bipolar dendrites and cone pedicles. (C) Pie charts displaying the average proportions on the three positional classes of synapses. Data are imply ?SD for every single bipolar cell kind (quantity of cells): IMB (6), BB (7), DB4 (six), DB5 (7), DB6 (5), GB (two) with SD (A-C). (D) A comparison of M/L-cone (left-handed bars, n = 12) and S-cone (right-handed bars, n = six) divergence for the six varieties of ON bipolar cells. The abscissa is the typical quantity of contacts of a cone with every single variety of bipolar cells with the SD bar. (E) Pie charts comparing M/L-cones and S-cones within the innervation of distinct bipolar kinds. (F) Three positional classes of contacts: invaginationg, TA, and NTA inside the ON and OFF routes diverging from an M/L-cone pedicle (P41) and an S-cone pedicle (P39) both located inside the center of the examination area (Figure 5).Frontiers in Neuroanatomy | www.frontiersin.orgOctober 2016 | Volume 10 | ArticleTsukamoto and OmiMacaque ON Bipolar Cell ConnectivityTABLE 1 | Synaptic convergence of cones onto every ON bipolar cell kind.
