基于完全图的脑功能时序网络模式及其能量动力学研究

Revealing the human brain functional cognition would provide an opportunity to break the bottleneck of current artificial intelligence developments. Brain functional cognitive dynamic network modelling is one of very important approaches. In this project, we explore the brain functional time series network model based on the complete graphs and its energy dynamics. We transcribe brain functional activities into the multi-voxel time series with frequency, phase and amplitude. Using the frequency and phase of time series, we present a features extraction algorithm from brain functional activities to avoid the false positive and false negative in statistical tests. According to the dense trait of the network topology model, the brain functional network reconstruction approach based on complete-graph skeleton is proposed to solve the non-robust problems caused by noise and non-equilibrium. And then we investigate the dynamics about the brain functional networks through the phase and energy spectrum of its time series, in which the evolution of the networks are deduced by the phases of time series, and the energy fields are derived from its amplitudes. We will also depict the cognitive states and evolution processes in human brain language cognition contrasting Chinese and English to simulate the changes and transitions of energy fields and conscious streams with different periods. This research work will provide important approaches to understand the brain functional language cognition and to analysis the mind and intelligence of human beings.
