Welcome to the Institute for Advanced Simulation (IAS-6), Computational and Systems Neuroscience

The brain is a highly complex organ and ubiquitous in our daily lives. However, little is understood about it or its functions. Undertaking the study of this organ is a challenging and fascinating endeavour and can spawn new technologies and alternative methods of treatment of diseases. Research at the Institute of Computational and Systems Neuroscience encompasses theoretical, data-analytic and simulation approaches to develop multi-scale models of the brain. It is our firm belief that progress in understanding a complex system like the brain can only be achieved through this multi-faceted approach.

Computational Neurophysics

The focus of the group of Markus Diesmann are bottom-up approaches in order to integrate physiological and anatomical data into models, in particular model development, theory of neuronal networks, and correlation dynamics. This also requires the development of simulation technology for neural networks.

Lead: Markus Diesmann, Director of IAS-6/ INM-10

Statistical Neuroscience

The research group of Sonja Grün focuses on the development of analysis strategies and tools that uncover concerted activity in electrophysiological signals from the brain.

Computation in Neural Circuits

Investigation of mechanisms underlying neural computation through the development of models on the level of networks of spiking neurons. The group of Abigail Morrison applies a predominantly top-down approach to discover functional constraints on structure, plasticity and dynamics, particularly with respect to learning and memory.

Theory of Multi-Scale Neuronal Networks

Moritz Helias' group focuses on mechanisms that shape the dynamics and information processing in biological and artificial neuronal networks. On the side of biological networks, we are interested in the relationship between the structure and dynamics of neural networks to unveil experimentally testable mechanisms of collective phenomena. For artificial neuronal networks, we develop the physics of AI that allows us to understand and quantify generalization properties and learning. Employing and developing statistical physics methods to formulate biological and artificial networks in a unified language, allows us to discover overarching principles of information processing and to detect and quantify qualitative differences.

Theoretical Neuroanatomy

The work group led by Sacha van Albada studies the architecture and connectivity of brain circuits as the basis for neural network models at the resolution of neurons and synapses that relate structure to dynamics.
