A single IMB and 7 DB cells had a total of 39 invaginating contacts with P41, whereas four BB cells had 43 invaginating contacts with P39. Thus the invaginating contacts outnumbered the ribbonsFrontiers in Neuroanatomy | www.frontiersin.orgOctober 2016 | Volume ten | ArticleTsukamoto and OmiMacaque ON Bipolar Cell ConnectivityFIGURE five | Abundance of your three positional classes of synaptic contacts more than the complete cone region for every ON bipolar cell form. A group of ON bipolar cells from the exact same form shows a characteristic distribution of contacts with cone pedicles. Three 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 applied 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 amount of cones converging onto each and every bipolar cell (every cone was equally counted as unity regardless of the number of contacts). (B) The total variety of contacts from the three positional classes between bipolar dendrites and cone pedicles. (C) Pie charts showing the typical proportions of your three positional classes of synapses. Data are mean ?SD for every single bipolar cell variety (number of cells): IMB (6), BB (7), DB4 (six), DB5 (7), DB6 (5), GB (2) 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 kinds of ON bipolar cells. The abscissa is definitely the average number of contacts of a cone with each type of bipolar cells with all the SD bar. (E) Pie charts comparing M/L-cones and S-cones inside the innervation of distinctive bipolar varieties. (F) 3 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 in the center of your examination region (Figure five).Frontiers in Neuroanatomy | www.frontiersin.orgOctober 2016 | Volume ten | ArticleTsukamoto and OmiMacaque ON Bipolar Cell ConnectivityTABLE 1 | Synaptic convergence of cones onto every ON bipolar cell form.
