![]() Caption: A keyframe image for a 90 section subvolume of retinal connectome RC1. RC1 is composed of over 340,000 transmission electron microscope (TEM) images from 341 sections spanning a 250 μm diameter tissue column, assembled into single analysis volume parsed by the Viking application. The subvolume, 17.8 μm wide with a native resolution of 2.18 nm/pixel, was designed as a public test volume for tracking algorithms. The six colored processes have different topologies that vary in tracking difficulty: yellow > green > red > lavender > blue > cyan. |

![]() Microneuromas: An image of GABA signals showing extensive microneuroma formation in the hrhoG degeneration model (*.tif) at full (1024 x 768) Keynote or Powerpoint resolution with LZW compression. Microneuromas are rewiring tufts of varying size: as small as 10 µm to over 200 µm. They are not visible in normal histological preps but with hi res, hi def immunocytochem, they are clearly profuse. In some rodents they are present at 10,000-30,000 / retina. That only includes the larger, more obvious ones. The double circled tuft is actually in the RPE layer, outside the retina.© REM 2005 |
![]() Advanced remodeling in the human retina: A fully labeled multispectral image (taurine=red, glycine=green, glutathione=blue) of human RP retina in advanced stages – the patient had been completely blind for decades. Full (1024 x 768) Keynote or Powerpoint resolution with LZW compression. This tissue bears no resemblance to retina nand was drawn from a dataset spanning 19 mm of retina. All was of similar disorganization.© REM 2005 |
