Hi players, we made some bug fixes for the feature to use the Connect-the-Dots tracing tool to end a trace on an existing node. This again will allow you to repair fragments or disconnected parts of the neuron traces. A fully connected structure is most useful for the scientists so fixing these gaps with this tool is an important task. View details on this page.

You can disable the feature to end at an existing node by toggling the ‘Snap to Node’ option in the menu.

Also included is a bug fix for the auto-z tool to address the node placement jumping around too much along the xy plane.

Full change log at the bottom on this page.

Hi players, here are the neurons that are closing this week:

Today July 25: Mouse-ALM-19

Tomorrow July 26: Human-TC-13

Friday July 28: Human-TC-12 Mouse-V1-50

New ones will be posted to replace them at around 5pm.

A new round of scientist feedback and results is up now! Players have been doing an exceptional job tracing dendrites. There are still some false-positives making their way into consensus. Keep in mind as you trace that if it can’t be followed back to the main structure, it’s probably not real signal. Check out the results below for each challenge!


Thank you, players, for your continued contributions and patience. Mozak wouldn’t exist without you guys! We appreciate every trace, every bug report, and every feedback post.

Hi players, our partners at AIBS did a review of the neurons currently posted and have some new estimates of how complete the traces look. New comments have also been added on several neurons.

Much of the work left to do is faint axon, you might need to zoom in closer and utilize the Connect-the-Dots tool in order to accurately trace those parts out.

Finally some encouraging words from the scientists regarding your work:

“Overall I am impressed by two things:

1) The completeness of the dendrites in every cell that has been up for more than a few days.

2) The lack of false positives. In all these cells I only saw one instance of an obvious false positive.”
