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
A1is 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 (
- But 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)?
