Frequently Asked Questions

I can no longer attend CCN 2025. Can my co-author present my poster?

Please reach out to the Technical Programme Committee (tpc@ccneuro.org) to request to change the “Presenter” to your co-author on your submission. Presenters are identified via submission metadata on OpenReview.

However, please note that Presenters need to be unique across both tracks at CCN 2025 (i.e., an individual can be listed as Presenter on no more than one Proceedings paper or Extended Abstract), and that each Presenter must pay for a registration at CCN 2025. However, we acknowledge that things come up: In the event that the Presenter can’t attend CCN 2025 in person, we won’t withdraw the work and a co-author can put up the poster; however, the Presenter must stay registered.

I can no longer attend CCN 2025. Can my co-author present my talk?

Talks selections are determined based on submissions and their Presenters jointly. As such, we won’t be able to transfer a talk to a different Presenter, unlike with a poster (see the above question).

I and my co-authors can no longer attend CCN 2025. How can I withdraw my poster?

Please use the “Withdrawal” function on the OpenReview page for your submission.

  • Do I and all my co-authors need an OpenReview account to submit an Extended Abstract?

  • OpenReview accounts are required for: the individual making the submission, the Reciprocal Reviewer(s) identified on the submission, and the Presenter identified on the submission. Other co-authors do not need an OpenReview account; you can simply input their name and email.

To sign up for an OpenReview account, follow the instructions at Signing up for OpenReview. If your profile is not immediately activated (because OpenReview does not recognize the institution corresponding to your email domain), please follow OpenReview’s instructions at Expediting Profile Activation.

  • What is the timezone for the deadlines?

  • “Anywhere on Earth” or AOE; (UTC-12). You can think of this as midnight, your time. (In most time zones it ends up being several hours after midnight.)

How should I format the anonymized author block?

Please use the anonymized title-author block included in the templates; see below. Do not duplicate this block (e.g., according to the number of anonymized authors of the manuscript). In particular, each anonymized submission to either CCN track should have a similar-length title-author block (modulo a single- or double-line title).

[Your title]

Anonymous Authors\ Double blind review

Can we have shared first or last authorship?

Yes. You still must choose a fixed ordering of authors in the submission form.

Can I include keywords?

  • These are not necessary. We match reviewers and categorize submissions according to your full-text abstract.

Can I include acknowledgements?

  • In the post-decision, “camera-ready” version, yes. Please omit this from the anonymized submission to be reviewed. If acknowledgements are inadvertently included in the anonymized submission, we may have to desk-reject it for failure to meet the double-blind reviewing requirements of CCN 2025.

Can I include supplementary material?

  • No; the Extended Abstracts track will not allow supplementary material of any kind.

Yes, we encourage code submissions as evidence of reproducibility. However, note that a code repository takes extra effort to anonymize, and we will desk-reject submissions that accidentally de-anonymize their authors via a linked code repository with identifying information.

We recommend Anonymous GitHub as a service that helps to anonymize a GitHub-hosted code repository, but we allow links to any hosting service as long as they maintain anonymity. We suggest including a link to the anonymous repository in a footnote in the PDF.

Please remember to avoid naming the repository or the exact package name if it is already publicly available. You can add the name and repository URL back in during the post-decision / camera-ready phase.

Do references count towards the 2-page limit?

  • No.

How should I format equations?

We don’t prescribe a particular format. The APA standard is OK, for example.

Can I preprint the manuscript that I plan to submit to CCN?

  • Papers to both tracks must be submitted fully anonymized. Authors may disseminate their work publicly under their names (e.g., on a preprint server), but are asked to refrain from publicizing (e.g., on social media) work under review at CCN until CCN decisions are released for all tracks (all-decisions) to prevent accidental de-anonymization during the review process.

Can I submit my manuscript to another publication venue (e.g., a conference or journal) or submit such a manuscript to the Extended Abstracts track?

  • The Extended Abstracts track does not allow the submission of manuscripts that have been published elsewhere. The Extended Abstracts track does however allow manuscripts that are under review elsewhere (“concurrent” or “dual” submissions), unlike the Proceedings track. Accepted Extended Abstracts will not receive a DOI assignment this year.

Should I submit my Proceedings submission to the Extended Abstracts track?

There is no need to submit a Extended Abstract version of your Proceedings submission to the Extended Abstracts track. Authors of Proceedings submissions that are not accepted will be invited to convert their Proceedings submission to an Extended Abstract submission. Instructions for this will be provided at a later stage.

Can I make multiple Extended Abstract submissions?

CCN 2025 maintains the historical policy that a given presenter can present only a single contribution at CCN. As such, you can make only one submission as the “Presenter” (the presenting author as identified on OpenReview) to the Extended Abstracts track. We will desk-reject submissions in violation of this requirement between desk-rejection-review-period. You can participate in any number of submissions for which you are an author You can participate in any number of submissions for which you are an author but not the Presenter.

But see “I can no longer attend CCN 2025. Can my co-author present my poster?”

Can I make an Extended Abstract submission if I have already made a Proceedings submission?

Yes. Since CCN 2025 has two tracks with separate timelines, we allow Presenters to submit a contribution to each track. If both contributions are accepted for presentation at CCN 2025 (*), the Presenter will be asked to select one of their contributions for presentation and withdraw the other. This selection must be made between presenter-selection-period, after decisions are announced for all tracks.

(*) This can occur if a Presenter has both a Proceedings paper and an Extended Abstract accepted, or a Presenter’s Proceedings paper is invited to the Extended Abstract track after they have submitted a contribution directly to the Extended Abstracts track. However, as noted above, we do not allow multiple submissions from a single Presenter to the Extended Abstracts track.

But see “I can no longer attend CCN 2025. Can my co-author present my poster?”

Will my extended abstract be copyrighted?

By submitting your abstract to CCN 2025, you agree to have the Creative Commons Attribution 4.0 Deed License applied to your work. Under this license, you as the author agree that anyone can copy, distribute, or reuse your article in whole or part for any purpose, for free, as long as the author and original source are properly cited. This facilitates freedom of re-use and ensures that content can be mined without restriction.

CCN places no restrictions on future reuse or publication of content contained within a CCN paper.

I was told that my submission has formatting issues and won’t be reviewed. Can I revise them and still enter review for a Contributed Talk?

Unfortunately we have already started the technical process of starting the review process so won’t be able to wait for revisions. Please wait until the camera-ready phase in late May to submit your corrected manuscript for publication. Further instructions for how to do this will follow.
