Title: Connectomics: extracting neural connectivity from very large data sets
Abstract: Connectomics is the study of neural connectivity. Using images from electron
microscopes, we automatically identify nanometer-scale structures in microtomed brain
tissue. We work with slices and images at a resolution where a cubic sample one
millimeter on a side produces more than one petabyte of image data.
To deal with such large datasets requires a mostly-automated approach. Our analysis
pipeline uses computer vision, machine learning, and cluster computing to produce an
initial version of the connectome within a sample. We then use a web-based proofreading
and annotation tool to allow multiple simultaneous users to explore and correct the data
within the volume.
