09.10.2012 A glance at the brain’s circuit diagram
A new method facilitates the mapping of connections between neurons
The human brain accomplishes its remarkable feats through the interplay of an unimaginable number of neurons that are interconnected in complex networks. A team of scientists from the Max Planck Institute for Dynamics and Self-Organization, the University of Göttingen and the Bernstein Center for Computational Neuroscience Göttingen has now developed a method for decoding neural circuit diagrams. Using measurements of total neuronal activity, they can determine the probability that two neurons are connected with each other.

18.06.2012 Self-organization of electric power grid dynamics
In future smart grids, the distribution of consumer demands shall be controlled as to efficiently match electric power production. Such control requires a through understanding of how the grid self-organizes its collective dynamics in the absence of control. We are now providing a new perpective using mathematical oscillator models of power grids.
One main conclusion: adding new connection lines may not only help but also prevent power grid synchrony and thus cause power outage.

06.05.2012 Non-Additive Amplifier in Neural Circuits
Non-additivity enables synchrony propagation in recurrent networks
So far, models of neural circuits typically assume that inputs to a neuron add linearly and are only nonlinearly processed thereafter. Recent experiments show that a non-additive processing acts at single neurons if excitatory inputs appear synchronously and in sufficient proximity on the dendrite. The current study now provides a systematic view on how such non-additivity impacts the collective dynamics of networks.
One main finding is that even purely random networks may exhibit robust propagation of synchronous activity (synfire chain activity) even without superimposed feed-forward structures (so far known as synfire anatomy).

08.12.2011 Chaos Despite Symmetry
The collective dynamics of many systems in biology and physics are well characterized by strongly coupled limit cycle oscillators, ranging from certain neural circuits to coupled Josephson junctions. So far it was believed that symmetry in these system forces the collective dynamics to be regular, for instance periodic. A new study has now uncovered that equally chaos can emerge in such system, and in which forms it does.
The study is published in Physical Review Letters

Bernstein Lecture Series SS 2008
Selected chapters of Biophysics written by outstanding female scientists.
This semester the Bernstein Lecture Series invites outstanding female researchers in the field of biophysics to speak in Göttingen. The scientists from the USA and Germany will not only give an overview over their work, but also allow young female researchers and students to meet experienced and successful role-models. This semester’s focus is on neural networks and brain research. On Tuesday, July 8th, Prof. Dr. Elly Nevidi from the Massachusetts Institute of Technology in Boston will talk about a dynamic zone defining interneuron remodeling in the adult neocortex.
The Lecture Series is organized by female PhD students from all divisions of the Max-Planck-Institute for Dynamics and Self-Organization. Their aim is to help young female scientists in establishing a network of colleagues devoted to similar fields of research. At the same time the students can profit from the experiences the renowned lecturers made working and researching in different countries and get hands-on advice for their career planning.
The lectures are open to the public and can be a helpful experience for female students and researchers working in all fields of science. Before the talks, the invited scientists will give a short tutorial for interested students.

01.02.2008 Thinking too complicated?
How sensitive are neuronal networks to external interference? To what extent are neuronal network processes incudung the thinking patterns of the brain predefined? These questions have been investigated by Sven Jahnke, Raoul-Martin Memmesheimer and Marc Timme at the Bernstein Center for Computional Neuroscience and the Max Planck Institute for Dynamics and Self-Organisation. They have found out that, under certain conditions, neuronal networks are more predictable than was previously assumed (Physical Review Letters, Feb. 1st, 2008)
