Plasticity in NEUral Memristive Architectures

Beyond Autonomic systems - the Challenge of Consciousness

During the past two decades, philosophers, psychologists, cognitive scientists, clinicians and neuroscientists strived to provide authoritative definitions of consciousness within a neurobiological framework. Engineers have more recently joined this quest by developing neuromorphic VLSI circuits for emulating biological functions. Yet, to date artificial systems have not been able to faithfully recreate natural attributes such as true processing locality (memory and computation) and complexity (1010 synapses per cm2), preventing the achievement of a long-term goal: the creation of autonomous cognitive systems.

This project aspires to develop experimental platforms capable of perceiving, learning and adapting to stimuli by leveraging on the latest developments of five leading European institutions in neuroscience, nanotechnology, modeling and circuit design. The non-linear dynamics as well as the plasticity of the newly discovered memristor are shown to support Spike-based- and Spike-Timing-Dependent-Plasticity (STDP), making this extremely compact device an excellent candidate for realizing large-scale self-adaptive circuits; a step towards "autonomous cognitive systems". The intrinsic properties of real neurons and synapses as well as their organization in forming neural circuits will be exploited for optimizing CMOS-based neurons, memristive grids and the integration of the two into real time biophysically realistic neuromorphic systems. Finally, the platforms would be tested with conventional as well as abstract methods to evaluate the technology and its autonomous capacity.

ERA-Net CHIST-ERA

CHIST-ERA stands for "European Coordinated Research on Long-term Challenges in Information and Communication Sciences & Technologies ERA-NET". 

The focus of CHIST-ERA is long-term transformational research. Its principal objective is to reinforce the transnational collaboration between Member States in challenging multidisciplinary research in the area of ICST, and to integrate the related national research communities in Europe through the funding of transnational research projects.
