About this Research Topic
Biohybrid circuits are a type of neural interface that rely on the bidirectional communication between biological neurons (wetware) and neural models implemented in software and/or hardware. These neural interfaces have numerous applications in experimental and clinical neuroscience, including closed-loop electrophysiology, brain-machine interfaces, and neuroprosthetics.
Standard technologies severely limit the range of spatial and temporal scales with which we can interface the wetware with the software and hardware components. Experimentally, there is a trade-off between the accessibility of the level of biological organization and the number of individual neurons that can be recorded and stimulated simultaneously. For the software and hardware components, the real-time operation of biohybrid circuits imposes stringent design constraints on their communication, bandwidth, and memory architectures, resulting in a trade-off between the number of simulated neurons and their computational complexity.
The aim of this Research Topic is to provide an interdisciplinary overview of recent advances in biosensing technology, neuromorphic engineering, and memristive systems that can leverage the different trade-offs imposed on the wetware, software, and hardware components of biohybrid systems in order to scale up biohybrid circuits to the network level with single-cell resolution. We also aim to bring together researchers neuroscientists and neural engineers working on different continents and provide a platform to: i) discuss further research directions and applications for biohybrid systems; and ii) build a community of researchers and promote future international collaborative research efforts.
In this Research Topic, we welcome articles focused on the design and applications of biohybrid
