Background

Sleep is a vital physiological process involving dynamic transitions across distinct stages, each characterized by specific patterns of brain activity. Electroencephalography (EEG) remains the gold standard for studying sleep architecture, offering unparalleled temporal resolution of neural oscillations. However, conventional sleep stage scoring relies on predefined visual criteria and may not fully capture the complexity of neural interactions underlying different sleep states. Recent advancements have introduced measures of EEG complexity—such as entropy, fractal analysis, and machine learning techniques—opening new avenues for more nuanced and data-driven approaches to understanding sleep networks.
The primary objective of this Research Topic is to advance our understanding of how EEG complexity metrics can enrich the identification, characterization and modeling of sleep stages, thereby offering deeper insights into the neural networks that regulate sleep. Traditional scoring systems, while clinically useful, often overlook subtle dynamics and individual variability inherent in neural signals. By integrating methods that quantify EEG complexity, researchers may reveal hidden features that distinguish sleep stages, track neurophysiological changes across the lifespan, and improve diagnostic precision in sleep-related disorders. We aim to compile research that not only pushes the boundaries of analytic methodologies but also translates these advances into practical tools for sleep medicine and neuroscience. Through this collective effort, we hope to foster innovations that enhance both fundamental knowledge and clinical applications in sleep research.
This Research Topic invites contributions that integrate advanced EEG complexity analysis and modeling with sleep stages identification to unravel the neural networks governing sleep. We encourage submission of original research articles, reviews, mini-reviews, and methodological perspectives on:
o Novel approaches to quantifying EEG complexity during various sleep stages
o Integration of complexity metrics with traditional sleep scoring
o Modeling sleep processes on different temporal scales relating it with cardiac and respiratory systems
o Machine learning and computational models for automated sleep stage classification
o Correlations between EEG complexity, sleep functions, and health outcomes
o Comparative studies across populations or patient cohorts
o Validation of complexity-based measures against clinical gold standards

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 it falls 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.
