Synopsis:
Understanding complex systems composed of many interacting units, such as neural networks, means understanding their directed and causal interactions. If the units in question interact in a nonlinear way, as it can be assumed in neural networks, we are faced with the problem that the analysis of interactions must be blind to the type of interaction if we want to cover all possible interactions in the network, as we may not know the type of nonlinear interaction a priori. Prematurely limiting our search to specific models, nonlinearities or, even worse, linear interactions may block the road to discovery. Novel model-free techniques for the quantification of directed interactions from information theory offer a promising alternative to more traditional methods in the field of interaction analyses, but also come with their own specific challenges. This symposium brings together the most active researchers in the field to discuss the state of the art, future prospects and challenges on the way to an model-free, information theoretic assessment of neuronal directed interactions.

Course:
TRENTOOL (www.trentool.de) is a recently published MATLAB® toolbox for the model-free analysis of directed interactions in neural time series. As indicated in the schedule below, participants of the symposium will have the opportunity to get a hands on tutorial in the use of TRENTOOL on the two afternoons of the symposium (limited places!).
