Organization in complex brain networks: energy distributions and phase shift

Publication date: Available online 24 May 2019Source: Journal of Theoretical BiologyAuthor(s): Saurabh Kumar Sharma, Soibam Shyamchand Singh, Dineshchandra Haobijam, Md. Zubbair Malik, R.K. Brojen SinghAbstractThe Hamiltonian function of a network, derived from the intrinsic distributions of nodes and edges, magnified by resolution parameter has information on the distribution of energy in the network. In brain networks, the Hamiltonian function follows hierarchical features reflecting a power-law behavior which can be a signature of self-organization. Further, the transition of three distinct phases driven by resolution parameter is observed which could correspond to various important brain states. This resolution parameter could thus reflect a key parameter that controls and balances the energy distribution in the brain network.Graphical abstract
