About this Research Topic

Background

Neural coding, a cornerstone in neuroscience, investigates how neurons encode sensory data and transmit it through networks to create meaningful sensory representations. This collection of articles delves into recent advancements in neural coding principles that underpin sensation, exploring diverse coding strategies and their roles in generating responses to sensory stimuli. At its core, neural coding seeks to characterize how stimuli relate to individual or collective neuronal responses, as well as the interconnected electrical activity within neural ensembles. Sensory information from the periphery travels through synaptically linked neurons, with each neuron encoding information by modulating the rate and timing of its action potentials. Changes in spiking patterns across neuronal populations form the basis of sensory representations. Sensory coding elucidates how various stimuli are encoded through distinct neural activity patterns and how single-trial neural activity is utilized to inform behavioral decisions. Recent progress underscores the concept of multiplexed encoding, where different neural codes operating on various timescales encode complementary stimulus features, collectively enhancing the system's encoding capacity. Consequently, there is a pressing need to further investigate neural coding principles and the contributions of each neural code to the overall response to sensory stimuli across various sensory systems. The development of hardware implementations of neural codes is crucial for real-world neuromorphic computing applications, particularly for edge computing tasks. Therefore, exploring more efficient neural encoder implementations and multiplexing encoders with higher data capacity holds promise. This issue also aims to discuss both field-programmable gate array (FPGA) and integrated circuit (IC) realizations of neural encoders with high data capacity and how these implementations respond to noise impacts. By spotlighting recent advancements in neural coding principles, this collection of articles aims to deepen our understanding of how different coding strategies contribute to sensory perception, action manifestation, and the impact of internal or external noise on these coding paradigms.

This research topic aims to deepen our understanding of how different neural coding strategies contribute to sensory perception, action manifestation, and the impact of internal or external noise on these coding paradigms. Specifically, it seeks to answer questions about the contributions of various neural codes to the overall response to sensory stimuli across different sensory systems. Additionally, the research will test hypotheses related to the efficiency and capacity of neural encoder implementations in real-world applications, particularly in the context of neuromorphic computing.

To gather further insights into the boundaries of neural coding, we welcome articles addressing, but not limited to, the following themes:
- Multiplexed encoding and its role in sensory information processing
- Single-trial neural activity and its influence on behavioral decisions
- Hardware implementations of neural codes, including FPGA and IC realizations
- The impact of internal and external noise on neural coding strategies
- Comparative studies of neural coding across different sensory systems
- Advances in neuromorphic computing and edge computing applications
- Theoretical models and simulations of neural coding mechanisms

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?

  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.
