A group of ON bipolar cells of the similar sort shows a characteristic distribution of contacts with cone pedicles.Edicle P39 had 34 ribbons. Each quantity of ribbons is close to its mean value title= s13578-015-0060-8 at three mm eccentricity (Imply ?SD: 31.3 ?3.four M/L-cone, n = 23; 31.eight ?two.eight for S-cone, n = ten, Tsukamoto and Omi, 2015a). 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.Edicle P39 had 34 ribbons.

A group of ON bipolar cells of the exact same sort 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 utilized for contact 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.
