Event Abstract

neuroVIISAS: The Integration of Atlases and Connectomes for Modeling

  • 1 University of Rostock, Anatomy, Germany

Modeling supports the understanding of complex biological systems like nervous systems and whole organisms. The building blocks to generate models of organisms are heterogeneous and involve multiple structures (organs and their subdivisions, regions of the CNS and their connections) and functions (motor action, perception, dynamics of the stimulus-response behavior). neuroVIISAS (neuro Visualization, Imagemapping, Information System for Analysis and Simulation) is build to allow the integration of structures in terms of 3D-reconstructions, connections and modeling of neuron populations (Schmitt and Eipert, 2012). It is an open environment with regard to import and export of data and a generic tool that can be used for the development of digital atlases, brain mapping, connectome and simulation projects of all types of nervous systems. For the modeling of populations of neurons the NEural Simulation Tool (NEST v 2.2.1) is used (Gewaltig and Diesmann, 2007). This approach enables the modeler to use more realistic connectome data for an accurate definition of connections between populations of neurons in NEST. How this is achieved will be demonstrated with examples of basal ganglia networks (Fig. 1). Furthermore, the interactions of visualization, simulation and analysis of complex neuronal networks will be shown. In addition to high level analysis and visualization functions of neuroVIISAS the import of connectivity data will be explained. The software can be downloaded from http://neuroviisas.med.uni-rostock.de/index-Dateien/Page455.htm.

The smart organic graph layout with orthogonal bus router and symmetry option displays the color coded bilateral connections.
