DFG Research Group 2093

The research group focuses on the transmission of neuronal, synaptic plasticity and information storage to an analog curcuit technology with nanoelectronic, memristive components. What is challenging is to transmit the synaptic plasticity as a basis of learning and memory processes in biological systems onto memristive circuits. Here, neurobiological cellular mechanisms like those found in neurons and synapses are simulated within memristive components. Cellular forms of learning and memory are to be reconstructed so that both implicit and explicit learning processes can be technologically replicated. Through a detailed characterisation of the static and dynamic characteristics of memristive components and through the replication of cellular learning mechanisms with  by means of memristive systems, learning and memory processes are supposed to be emulated into network circuits that are inspired by neurobiology. For this purpose, neurobiological switching processes are adapted based on the special structure of the hippocampal trisynaptic circuit. The adaptation of the neurobiological switching pocesses closely follows the learning and memory processes in the hippocampus of mammals. The hippocampus represents the central brain area responsible for memory, learning, and pattern separation and pattern completion. The goal of the research group is it to realise the function sequence in the trisynaptic hippocampal circuit within a memristive circuit. We also want to solve the question whether neurological concepts of cognitive maps and place cells can be transferred to analog circuit architectures. We want to reach this ambitious goal with the help of a network of researchers who have expertise in complementay research areas.
