\nUnderstanding of higer brain function is one of the most important scientific issue for human beings. For the purpose, analysis of brain functional data obtained through medical devices such as EEG, ECoG, and fMRI takes a role of importance. In this study, we had promoted research and development on brain funtional analysis system for MEG (magnetoencephalography), which can detect the change in magnetic field caused from brain activities, by leveraging Grid computing technology. Speficially, the system allows scientists to efficiently perform wavelet analysis to brain functional data obtained from multiple MEG sensors and then cross-correlation analysis to the anlyzed data on a Grid environment composed of multile computational resources, each of which may be located on a different organization. Also, we had worked on visualization software of analysis results.
