FOR 2093

The goal of the research group is the technological simulation of neuronal information processing in the trisynaptic circuit of the hippocampus based on memristive devices.

The main focus of the research group is the transfer of the neuronal, synaptic plasticity and information storage into an analogue circuit technology with the help of nanoelectronic, memristive devices. The challenge will be to transfer synaptic plasticity mechanisms as a basis of learning- and memory processes in biological systems to memristive technological circuits. This includes the simulation of neurobiological cellular mechanisms as they occur in neurons and synapses via memristive devices. The aim is the structural and technological reconstruction of cellular learning- and memory forms that enable the simulation of implicit and explicit learning processes. A detailed characterisation of static and dynamic characteristics of memristive devices and a simulation of cellular learning mechanisms by using memristive systems enables the emulation of learning- and memory processes in neurobiologically inspired network circuits. Furthermore, we aim to adapt neurobiological circuit processes based on the special structure of the hippocampal trisynaptic circuit that closely adhere to the hippocampus of the mammalian brain. The hippocampus represents the central brain area for memory, learning and separation and completion of patterns. The aim of the research group is the simulation of functional sequences within the tri-synaptic, hippocampal circuit in a memristive circuit. This includes clarifying to what extent it is possible to transfer neurological concepts of cognitive maps and place cells to analogue circuit architectures. The research group aims to reach this ambitious goal through a network of scientists with complementary expert knowledge.
