In the present study, we propose a theoretical graph procedure to investigate the communication redundancy in brain networks. By taking into account all the possible paths between pairs of cortical regions, this method captures the network redundancy i.e. a critical resource of the brain enhancing the resilience to neural damages and dysfunctions. As an example for its potential, we apply this procedure to the cortical networks estimated from high-resolution EEG signals in a group of spinal cord injured patients during the attempt of the foot movement. Preliminary results suggest that in the high spectral contents the effects due to the spinal trauma affect the expected redundancy attitude by suppressing mainly the longer alternative pathways between the cortical regions.
在本研究中，我们提出了一种理论图形程序来研究脑网络中的通信冗余。通过考虑皮质区域对之间的所有可能路径，该方法捕捉到了网络冗余，即大脑的一种关键资源，可增强对神经损伤和功能障碍的恢复能力。作为其潜力的一个例子，我们将此程序应用于一组脊髓损伤患者在尝试足部运动期间从高分辨率脑电图信号估计的皮质网络。初步结果表明，在高频谱内容中，脊髓创伤产生的影响主要通过抑制皮质区域之间较长的替代路径来影响预期的冗余态势。
