About this Research Topic

Background

Description:

Quality control (QC) has long been an important part of FMRI processing, but it is typically underreported and too often underappreciated, whether for small or large, public or local datasets. This project aims to showcase examples of QC practices across institutions and to foster discussions within the field. Here, we welcome researchers and developers across the globe to describe their QC methods in detail and to show them "in action" for a varied dataset acquired across multiple sites and scanners.

Current imaging practices and acquisition details vary widely across the neuroimaging community, depending on study aims, available hardware and more. QC procedures then typically vary along with these different acquisitions (for example, different criteria are relevant to single- or multi-echo data), as well as by software used and by the people interpreting it. The current project focuses on what is likely the most common MRI acquisition protocol both historically and today: non-accelerated (single-band) FMRI. QC for single-band EPI datasets is in some ways the foundation for all others; it is something that all neuroimaging researchers will encounter either directly or indirectly through the literature, making it the ideal target for the current project. To provide a common set of examples with which to demonstrate different QC practices, we have gathered data from several open, public FMRI repositories: specifically, datasets which have already been used in many studies and can be considered fairly representative of MRI data forming the basis of studies in the field.

We welcome researchers to present their quality control assessments of the subjects in the provided data collection, listing which would be included or excluded from further analyses, and which might be considered borderline or "uncertain." Both task and several resting state cohorts are included, and participating researchers can choose to examine either or both of these types of data.

The goals of this project are:
- for researchers to be detailed and didactic about their quality control methods
- to present possible QC pipelines (with an emphasis on visualization and understanding) in the context of several "real world" data packages
- more broadly to share ideas of quality control among all researchers

We welcome submissions of Original Research, Methods, Brief Research Reports, and Technology and Code articles focusing on the quality control (QC) of this project's provided resting state FMRI data, task-based FMRI data, or both sets. The data details and download links are provided in the accompanying OSF page, along with descriptive items to be included in the submitted articles.

We fully expect that no two groups perform QC the same way, and we note that there is no single "correct" set of QC steps nor one "correct" set of answers for categorizing subjects. We expect the results to show a diverse set of tools and ideas that can be applied generally to FMRI studies and to enrich the wider neuroscience community with useful ways to look at and understand their data. One main result of this project will be an assemblage of QC criteria from active researchers around the FMRI community, with detailed descriptions and examples.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and they fall under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

• Can I suggest a new Research Topic? 

  Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.

• Who leads a Research Topic? 

  A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

  The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

• What is the role of a topic editor?

  As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

   

  You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

• What support will I receive when editing a new Research Topic? 

  As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

• As a junior researcher, can I be involved in editing a Research Topic? 

  If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor. This provides you with valuable editorial experience, improving your ability to critically evaluate research articles and enhancing your understanding of the quality standards and requirements for scientific publishing, as well as the opportunity to discover new research in your field, and expand your professional network.

• Can I get a certificate for editing a Research Topic?

  Yes, certificates can be issued on request. We are happy to provide a certificate for your contribution to editing a successful Research Topic.
