Connectomes

NeuroData's Graph DataBase

About

This page hosts animal connectomes produced using data from a multitude of labs, across model species, using different modalities. A 'connectome' is a specific, cell-to-cell mapping of axonal tracts between neurons, created from cellular data like electron microscopy. Animal models included are cat, fly, the macaque monkey, mouse, rat, and worm. Every graph is annotated with a source attribute that denotes its origin.

Graphs are provided by default in graphML format. This is the only format that supports iterable attributes.

For human graph data visit Projectomes.
