A reader asked for references to papers on EEG correlation experiments between isolated people. The following list may not be exhaustively complete, it is not in any particular order, and it includes a few fMRI studies. I am aware of at least one other published paper by Grinberg-Zilberbaum et al, but I don't have that reference handy. Study 5 is, I think, relevant but is not a psi study.
