About this Research Topic

Background

Synaptic plasticity (aka Neural Learning) has been an intensely studied topic in both experimental and computational neuroscience as it strives to uncover the brain’s underlying processes and corresponding “rule(s)” of how information is learned and stored. This area of research has been historically instrumental in understanding how neural circuits in the brain form and function, as well as in the development of learning rules used in various areas, including Artificial Intelligence (AI), machine learning, and neural networks (including deep learning). Previous studies have focused on various aspects of synaptic plasticity and how these translate into learning rules that can be implemented in simulations of neural networks to observe how information is potentially learned and stored within a simulated neural network. Over the last decade, there have been important contributions towards the understanding of learning in the brain, including the translation and application of these rules to various areas of engineering, such as implementing learning rules in neuromorphic hardware (including FPGAs), autonomous vehicles, AI-based applications for medical imaging, image recognition, and robotics. In parallel to such advances, there is increasing interest in the interaction between synaptic plasticity and the development of brain disorders. Many years have passed since the last research topic on models of synaptic plasticity first appeared in Frontiers in Computational Neuroscience, and given the numerous advances, it is beneficial to present the next research topic in this area.

This Research Topic aims to assemble the current status for both the theory of learning and computational models of synaptic plasticity in neural circuits. We plan to bring together papers focusing on how learning in neural systems shapes single neuron and network activity, as well as topological characteristics of neuronal networks and the role of synaptic plasticity in the development of cognitive function, and the impact on neural circuits leading to the manifestation of brain disorders, such as depression. It is important to develop a deeper understanding between the type of plasticity rule and the impact on neural and/or network activity, including the onset of neurological disorders resulting from plastic change. Notably, one needs a better understanding of how underlying biochemical processes manifests into learning and memory, along with their involvement in the emergence of brain or cognitive disorders. It is also important to observe how such learning rules support the development of AI-based applications and their application to studying brain function in normal and pathological conditions.

To gather further insights into the boundaries of synaptic plasticity research, we welcome articles addressing, but not limited to, the following themes:
- Novel experimental approaches for induction and expression of LTP/LTD
- Experiments and models that elucidate the molecular underpinning of synaptic plasticity
- The role of synaptic plasticity in the development and emergence of neurological disorders
- Spike timing-dependent plasticity and (Markovian and non-Markovian) reinforcement learning in single and networks of neurons
- Impact of learning rules in the single neuron, neuronal dendrites, and neural networks
- Synaptic plasticity’s role in the development and impact on cognitive function
- Calcium-based learning
- Molecular models of learning
- Experiments and models of synaptic tagging
- Life-long learning
- Learning in neuromorphic platforms including robotics
- Theory of neural learning
- AI-based applications to brain function and medical imaging

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?
