Background

The field of neurological and psychiatric diseases, such as dementia and depression, presents significant social challenges, with no fully established therapeutic and preventive medical approaches. Beyond medication, enhancing cognitive performance and stress resilience is crucial for improving quality of life (QOL), health management, and reducing medical costs. Recent research has highlighted the critical role of the brain-gut axis in brain and mental health. The brain and mental health is closely linked to stimulation from the gut through various pathways, including the vagal nerve, hormonal, and immune systems. Notably, vagal nerve activation can rapidly influence brain conditions, with stimulation originating not only from the gut but also from sensory organs like smell, taste, and skin. Despite various approaches to modulating the vagal nerve, such as microbiome modulation, nutritional ingredients, and transcutaneous vagal nerve stimulation, there remains a need for comprehensive investigation into their preventive and therapeutic effects on neurological and psychiatric diseases. These methods also hold promise for improving QOL in healthy adults.


This Research Topic aims to explore the advancements made over the past decade in the activation and modulation of the vagal nerve for brain and mental health. The primary objectives include answering specific questions about the mechanisms and efficacy of vagal nerve stimulation, testing hypotheses related to its therapeutic potential, and identifying optimal methods for its application. By addressing these aims, the research seeks to provide a deeper understanding of how vagal nerve activation can be harnessed to improve mental health and treat neurological conditions.


To gather further insights into the boundaries of vagal nerve activation and modulation, we welcome articles addressing, but not limited to, the following themes:

- Mechanisms of vagal nerve stimulation and its impact on cognitive and psychiatric function

- Clinical trials evaluating the efficacy of vagal nerve modulation in treating neurological and psychiatric diseases

- Pre-clinical research on the effects of microbiome modulation and nutritional ingredients on vagal nerve activity

- The role of sensory organ stimulation in vagal nerve activation and autonomic nervous modulation

- Comparative studies of different vagal nerve stimulation techniques

- Long-term effects of vagal nerve modulation on cognitive performance and stress resilience and cognitive performance

- Innovations in transcutaneous vagal nerve stimulation technology

- Reviews of current literature on the brain-gut axis and its implications for mental health


Topic editors Dr. Yasuhisa Ano and Dr. Takafumi Fukuda are affiliated with Kirin Holdings Co. Ltd. All other Topic Editors declare no competing interests with regards to the Research Topic subject.

Frequently asked questions

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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).

  • 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.
