About this Research Topic

Background

Within both a single-cell and systematic level, homeostatic neuronal function relies on a delicate equilibrium between excitatory and inhibitory synaptic inputs. Achieving this complex balance involves proper coordination between excitatory, glutamatergic, and inhibitory GABAergic signaling. Although either signaling pathway can fluctuate in response to internal and external stimuli, it is critical for the balance between excitation and inhibition to adapt to these changes in order to presume normal physiology and behavior. It is well understood that imbalances between excitation and inhibition are thought to contribute and exacerbate pathology across various neurological disorders. Specifically, previous studies have noted disruptions in GABAergic signaling as a potential focal point underlying this imbalance. However, further exploration is needed to fully understand the underlying mechanisms of dysregulated GABAergic signaling in neurological disorders, and its overall impact on disease-related phenotypes.

The goal of this Research Topic is to present an updated collection of research showcasing the presence of dysregulated GABAergic signaling across all neurological disorders. Numerous studies have already characterized disrupted GABAergic signaling in several neurodevelopmental, neuropsychiatric, and neurodegenerative disorders. However, further exploration is needed to determine the underlying mechanisms that contribute to pathological changes in inhibitory signaling in the brain. Imbalanced excitation and inhibition have previously been used as potential targets for therapeutics in both clinical and preclinical research. Therefore, it is critical to understand whether this imbalance is conserved across other unexplored disorders, and if it significantly impacts the progression of the respective disease pathology of interest. This Research Topic will furthermore highlight the overall impact of dysregulated GABAergic on disease-related pathologies across a range of neurological disorders.

For this particular Research Topic, the following themes are of interest. Both review manuscripts and data-driven manuscripts are allowed for submission:

•     Functional changes in GABAergic signaling across any neurological disorder.
•     Molecular mechanisms underlying disruptions in GABAergic signaling.
•     Functional presence and/or mechanisms indicating pathological switches from inhibitory to excitatory GABAergic signaling in neurological disorders.
•     Alterations in specific GABA receptor structure, function, expression, and diversity
•     Overall impacts of dysregulated GABAergic signaling on behavior in neurological disorders.

If authors wish to submit a data-driven manuscript, research using either clinical or preclinical models may be submitted for review.

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?
