Event-based softcore processor in a biohybrid setup applied to structural plasticity


George, Richard; Mayr, Christian; Indiveri, Giacomo; Vassanelli, Stefano (2015). Event-based softcore processor in a biohybrid setup applied to structural plasticity.

Abstract

The goal in neuromorphic engineering is to design circuits and systems which emulate the computational principles of biological nervous systems. As these circuits follow the same fundamental design principles as their biological counterparts, they represent an elegant solution for the design of bio-hybrid computing architectures. We present a neuromorphic bio-hybrid system in which electronic circuits are coupled directly to neuronal cell cultures for providing low-level access to biological signal processing. To form this bio-hybrid, we introduce a backbone system which allows the implements of different network topologies by routing Address-Event Representations (AER) of spikes from biological cells to neuromorphic circuits and vice versa. The use of a soft- embedded-processor realtime system allows the exploration of topology-evolving setups. The final goal in the application of this backbone system is the creation of a bio-hybrid neural network that is structurally plastic. Preliminary results have already been obtained in a first verification step, successfully forming a bio-hybrid neural network and thus promising a novel approach towards bioinspired Brain-Machine Interfaces.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
