Title: A Generalized Betweenness for Studying Network Performance against PerturbationsĪuthors: Xiaobing Hu (Beijing Normal University, CHINA)Ībstract: Betweenness is an important network property to study system performance against perturbations (such as random natural disasters and intended terrorism attacks). Coupling these regions according to the Macaque cortical network produces activation patterns strikingly similar to those observed in recordings from the brain. Our results help to connect recent experimental findings of the olfactory system and suggest that a part of the complicated activity patterns seen in the brain may be explained even without a full knowledge of its wiring diagram. The dynamical behavior of each such region has been described using a phenomenological model consisting of a pool of excitatory neurons coupled to a pool of inhibitory neurons, which exhibits oscillations over a large range of parameter values. To understand the large-scale dynamics of the brain, we simulate it at the mesoscopic level with each node representing a local region of cortex, comprising between 10^3-10^6 neurons. In this talk, we will explore this question by looking at the simulations of collective dynamics of a detailed network of cortical areas in the Macaque brain recently compiled from the CoCoMac database, as well as, a model of global coupled brain regions used as a benchamrk. How such communication between brain regions gives rise to the rich behavioral repertoire of the organism has been a long-standing question.

We would like to encourage more of our Asian colleagues in complex systems science to attend the CCS regularly, so that the worldwide community of complex system scientists can find out about the research that is being done in Asia. There are now large communities of complex systems scientists in China, Japan, and Korea, among other places in Asia.
