About this Research Topic

Background

Stress is an important complex physiological systems response aimed to prepare the body to handle the challenge(s) presented by an internal or external environment – a stressor or their combination. While a stress response to acute stressor is usually helpful to cope with the given challenge, a chronic exposure to long lasting stressors mostly of the psychological or social kinds can lead to cumulative physiological and psychological effects, resulting in the increasing risk of health problems including cardiovascular disease, metabolic disease, weakening of immune response, digestive problems and various psychological consequences. Dysregulation of the autonomic nervous system, potentially leading to a cascade of physiological effects that worsen individual health conditions is one of the crucial mechanisms of above mentioned associations. Early stress detection and its severity quantification are thus crucial not only to avoid potentially irreversible damage, but also to promote mental health and well-being in various daily-life contexts (e.g. at work or at home).

The widespread use of non-invasive and cost-effective wearable devices, combined with more efficient and available computational resources and enhanced signal processing techniques, is paving the way towards a real-time objective stress recognition using biosignals recording and analysis. Recently, methods from dynamical systems and information-theory, capable to quantify the changes in the dynamical interactions between various components of the controlled systems (according to the so-called “Network Physiology” approach), have been exploited for multilevel stress assessment. At the same time, many studies have demonstrated the feasibility of performing stress classification using artificial intelligence algorithms, including both machine and deep learning (either utilizing supervised or unsupervised approaches). These recent trends have resulted in promising results not only for stress recognition and classification, but also to better elucidate the complexity of physiological responses to stress.

This Research Topic aims at promoting investigation of methodological approaches derived from advances in bioelectronics, biosignal processing and artificial intelligence, as well as in basic and integrative physiology and clinical medicine, to provide insight on stress recognition and classification in network interactions of physiological systems from biosignals.

Therefore, we solicit reviews, systematic reviews, mini-reviews, original research articles, brief research or case reports, opinions, perspectives or general commentaries, and method papers which cover (but are not limited to) the following themes:
• current advances in the development of experimental protocols for stress elicitation;
• innovative hardware equipment for non-invasive recording of multimodal biosignals;
•novel signal processing and time series analysis methods;
• supervised and unsupervised machine learning and deep learning algorithms;
• dynamics networks approaches for assessing the effects of stress on physiological systems and their interactions.

Within these scopes, a particular emphasis will be devoted to the more detailed description and quantification of the physiological responses to stressors of different types and intensities, produced by a complex interplay of nervous, endocrine, immune and other systems involved in the stress response.

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.
