ECG
The reason why ECG can be read at a distance has to do with advances in sensors.
ECG can also be extrapolated from any number of sources such as facial capillaries with time delay.
EEG on the other hand is limited, the sort of signal strengths available are an order of magnitude less.
MEG again is very limited due to interference barring some fantastic advance in room temp SQUIDs.
I have all the parts to make an EEG machine but the problem is finding useful data: yes you can get a
form of control at least by concentrating but nowhere near the fidelity of a direct connection.
Incidentally its possible that human consciousness itself could be something we can one day control
and manipulate with relatively small electric currents and the correct feedback methods.
Work has been done with Xenon (Xe) anaesthesia and it has been said that this could be the key to
human hibernation if as some research shows Xe is neuroprotective.
