Ontogenesis and senescence of memory consolidation

About this Research Topic

Background

One of the fundamental stages of memory processing is consolidation in which initially labile memories are gradually moved to a more fixed state. Memory consolidation is a vulnerable stage of memory traces, and its stabilization could be affected by memory modulators depending on memory types. Synchronizing individual chronotypes, that vary with genetics, age and sex, with sleep timing and social time leads to better memory consolidation in health and disease. Recent research suggests that pharmacological interventions can have a significant impact on the process of memory consolidation. There are several different types of pharmacological interventions that have been shown to affect memory consolidation. For example, N-methyl-D-aspartate (NMDA) receptor agonists, such as D-cycloserine, have been found to enhance the consolidation of fear memories. Other classes of drugs, such as anti-inflammatory agents and glucocorticoids, have also been shown to influence the consolidation process. Furthermore, pharmacological interventions can be used to modulate other factors that influence the consolidation of memories, such as sleep quality. Disruptions in sleep can negatively affect memory consolidation, but medications that improve sleep can improve these outcomes. Women experience changes in hormonal levels during pregnancy and menopause that may affect memory consolidation. The role of circadian rhythm in memory consolidation is also relevant. Melatonin is a naturally occurring hormone that regulates sleep and wake cycles, and studies have suggested that it can modulate memory consolidation. The social environment can also have an impact on memory consolidation. Researchers have investigated how modulators of neurotransmitters like dopamine or oxytocin, can affect memory consolidation in social contexts.

This article collection seeks to explore the broad impact of memory modulators, specifically pharmacological interventions, on memory consolidation. Further research in this area is needed to better understand the mechanisms behind these different interventions, as well as their clinical implications. This article collection will draw on the expertise of researchers and clinicians across diverse fields, including pharmacology, neuroscience, and sleep medicine to provide a comprehensive and multidisciplinary perspective on pharmacological interventions and memory consolidation outcomes.

This Article Collection welcomes insights on, but not limited to, the following themes:

1. Pharmacological interventions that modify memory storage.

2. Characterization of process of memory storage across the lifespan.

3. Impact of sex and reproductive stage on memory consolidation.

4. Role of circadian rhythm on memory consolidation.

5. Effect of sleep on memory storage.

6. Interaction between the social environment and memory consolidation.

7. Memory consolidation in mental and neurodegenerative diseases.

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 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.

• 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?
