🏦 The BANC (said "the bank") 🏦 is the Brain And Nerve Cord, a GridTape transmission electron microscopy dataset of a female adult Drosophila melanogaster's entire central nervous system.

• This dataset was generated by Jasper Phelps and Minsu Kim in Wei-Chung Lee's lab at Harvard Medical School.
• 3D segmentation to extract the shapes of neurons and other objects in the dataset was performed by Zetta AI.
• The community proofreading and annotation effort is coordinated by FlyWire.

A manuscript describing the BANC is currently in preparation, aiming to be finished by the end of 2024. During this phase, we are happily sharing the unpublished, work-in-progress dataset with all interested researchers, although use is currently subject to a publication embargo as we prepare our manuscript. See the links on this page to FlyWire for more information.

General information about the dataset

Generating the BANC connectome required 5 main phases that each took roughly 1 year:

• 2020: Sample preparation (read details)
• 2021: Serial sectioning and electron microscope imaging (read details)
• 2022: Image alignment
• 2023: Automated reconstruction of cells & synapses (read details)
• 2024: Proofreading and annotation (see FlyWire-BANC homepage)
