Proofreading repository for the mouse brain


This document will act as an overview and FAQ for all your proofreading needs while in proofreading in one of our mouse brain datasets, which currently include “Minnie” (cortex) and “CA3” (hippocampus). Please read through these documents as a self-guided training, and return to them whenever you need a refresher.

Items highlighted in specific colors are specific to those datasets. Items with black text are applicable to all datasets (even if written with a specific dataset in mind).

Current dataset colors:

  • Minnie
  • CA3

Tutorial documents:

  1. Welcome to CA3 in the hippocampus! – An overview of the CA3 dataset and explanation of its scientific value
