Gautam Prasad, Josh Burkart, Shatanu H. Joshi, Talia M. Nir, Arthur W. Toga, Paul M. Thompson
2013 Lecture Notes in Computer Science  
We present a method for studying brain connectivity by simulating a dynamical evolution of the nodes of the network.  ...  The nodes are treated as particles, and evolved under a simulated force analogous to gravitational acceleration in the well-known N -body problem.  ...  This approach adapts a well known physics-based problem, the N -body simulation for dynamic modeling of particles under physical forces, imposing a dynamic structure on the nodes of the brain network.  ...

2014 Criticality in Neural Systems  
Essentially, all modeling of brain function from studying models of neural networks has ignored the self-organized aspects of the process, but has concentrated on designing a working brain by engineering  ...  This proposal is now supported by a wide body of empirical evidence at different scales demonstrating that the spatiotemporal brain dynamics exhibit key signatures of critical dynamics, previously recognized  ...  The point is that we could be fulling ourselves in choosing for our particular problem a description of the brain determined by graphs, constructed by nodes, connected by paths, and so on.  ...
