CoCoMac Citation Policy

If you use CoCoMac connectivity, cite both CoCoMac and the original tracing studies.

Status: Experimental

The new CoCoMac database system here at has not been officially released, and all connectivity matrices produced here should be considered experimental. The work in progress is outlined in this publication:
Rembrandt Bakker, Thomas Wachtler and Markus Diesmann (2012), CoCoMac 2.0 and the future of tract-tracing databases, Front. Neuroinformatics, doi: 10.3389/fninf.2012.00030.

If you decide to work with pre-release connectivity data nevertheless, you are asked to adhere to the following citation policy.

Citation Policy

It is our policy that when you write a publication that uses a CoCoMac connectivity matrix, you should cite both CoCoMac and all tracing studies that made a significant contribution to the matrix. We consider a tracing study significant if it contributed data to at least 5% of the nonzero elements of the matrix. When you view the connectivity matrix using the interactive search wizard, the contributing studies are listed just below the matrix.


An important objective of is to convert it into a community project. We do everything in our power to have it embraced by both modelers (data users) and anatomists (data providers) alike. For modelers CoCoMac is inherently attractive since it provides models with physical parameters. For anatomists, the motivation should come from the exposure that they get when submitting data to CoCoMac. This exposure partly comes from summary statistics on this website, but what ultimately counts are the number of citations.
