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.
Continuous Percolation with Discontinuities
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.

The collective dynamics on small world networks emerge in a broad range of systems including neural circuits, epidemic spreading networks and chemical reactions. Here a mathematical formula is provided that systematically predicts the dynamics on such networks.
