Complex networks in brain electrical activity [article]

G. Ruffini, C. Ray, J. Marco, L. Fuentemilla, C. Grau
2005 arXiv   pre-print
We analyze the complex networks associated with brain electrical activity. Multichannel EEG measurements are first processed to obtain 3D voxel activations using the tomographic algorithm LORETA.  ...  In particular, the analysis supports the idea that supra-temporal and inferior frontal data work together in the processing of the differences between sounds by highlighting an increased connectivity in  ...  Ruffini would like to thank Ed Rietman for valuable discussions, and in particular for pointing out the relevance of [6] .  ...
