Background

Attachment and romantic relationships are a cornerstone of human social experience, influencing emotional well-being, stress regulation, and overall health. Decades of neuroscientific research have revealed core neural structures, neurotransmitter systems, and endocrine processes that underlie romantic and parental attachment (e.g., Bartels & Zeki, 2004; Aron et al., 2005; Fisher et al., 2006; Acevedo et al., 2011). Despite exciting discoveries, key questions remain unanswered, and new methodological advances offer unprecedented opportunities to probe the mechanisms of love and attachment from multiple angles. Indeed, much remains to be understood and discovered. This special topic in Frontiers in Cellular Neuroscience, Frontiers in Human Neuroscience, and Frontiers in Behavioral Neuroscience invites contributions that explore the neurobiology of attachment relationships and related processes using cutting-edge techniques, theoretical frameworks, and interdisciplinary approaches. For example, integrating epigenetics, metabolomics, and behavioral genetics can provide a deeper understanding of how life experiences, environmental factors, and biological processes converge in shaping attachment and relationship dynamics. We encourage authors to consider the following themes, while remaining open to other proposals of relevant topics, as well as research articles, meta-analyses, reviews, theoretical, and case study papers.



Potential Topics of Interest:



1. Epigenetics and genetics in attachment and romantic relationships

• Epigenetic modifications associated with attachment formation or maintenance.

• Influence of early-life stress or caregiving experiences on romantic attachment via epigenetic pathways.

• Interaction between genetics, environment, and developmental factors in shaping adult romantic behavior.



2. Psychoneuroendocrinology of love and attachment

• Role of hormones and neuropeptides (e.g., oxytocin, vasopressin, dopamine) in acute romantic attraction and long-term bonding.

• Impact of stress hormones on relationship satisfaction and stability over time.

• Developmental and sex-related differences in neuroendocrine responses to romantic attachment.



3. Metabolomics and biomarkers of attachment and love

• Novel metabolomic approaches to uncover biomarkers that correlate with different stages of romantic love (initial attraction, passionate love, long-term commitment).

• Interplay between immune function, metabolism, and relationship quality.

• Use of advanced technologies (e.g., mass spectrometry, metabolomic profiling) to identify and characterize molecular changes during romantic bonding.



4. Integrative and translational perspectives

• Transdisciplinary approaches combining neuroimaging, behavioral genetics, and psychophysiology to investigate romantic relationships.

• Translational applications for enhancing relationship resilience, improving mental health, or informing couple therapy.

• Cross-cultural investigations examining whether and how neurobiological mechanisms of romantic love vary across different cultural and social contexts.



We welcome original research articles, systematic reviews, meta-analyses, methods papers, theoretical perspectives, and case study reports that address the neurobiology of attachment and romantic relationships. Submissions should be grounded in rigorous methodology and should state clearly how the study advances the current state of knowledge. We especially encourage interdisciplinary and cross-sector collaborations that integrate insights from fields such as developmental psychology, molecular biology, affective neuroscience, evolutionary biology, and clinical medicine.

Topic editors

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.
