With sophisticated techniques likes
ERP, it is possible to correlate certain EEG activity with certain overt/covert actions.
What I'm wondering is: is there a risk for 2+ overt/covert actions producing identical EEG activity? Meaning:
Perhaps when I go to open/close my right hand, I produce certain neural activity (lets just summarize this as
A1 is a specific set of wave signatures
Perhaps when I go to open/close my left hand, I produce neural activity
A2 (a specific set of wave signatures that is distinctively/mathematically different than
Perhaps there are 10,000 other movements I could make that produced their own distinct set of wave signatures (
perhaps when I think of sea turtles and pat my stomach at the same time, I produce the same set of waves as
A2 (opening and closing my left hand)
My question is: is this a concern/possibility with EEG/ERP? In other words, can multiple overt/covert intents produce identical wave activity (hence, identical EEG readings)?

To curtly answer your question: given the sheer amount of different
thoughts possible (billions I guess) and the limited spatial resolution of the standard EEG as well as the restricted number of characteristic parameters to describe EEGs (frequency, amplitude, latency) it is safe to say EEG is not suitable to characterize all of the brains processes. In fact, no state-of-the-art technique can do so, as far as I can see.
