Sorry not to be so clear.
Let me try again.
There is one or more, in this experiment exactly two person, with an EEG, the signal from EEG of these two person is digitalized and transmitted using a personal computer through internet to another PC that, based on this signal, using a TMS, stimulate the brain of the third person.
This person has also an EEG that get the reaction of his brain, convert it in an action, to rotate or not the tetris brick falling down.
Let me know if it's clear now.
