Is anyone aware of any concept of stimulus independent ERP (an apparent oxymororn, an event related potential that is neither sensory, cognitive nor motor elicited) ...or a procedure that looks specifically at noise waveform during ERP trials.....
Basically I am trying to think of an analogue of resting-state fMRI for EEG. My logic is that we can find a stimulus-independent ERP signature by a) either taking EEG values every say 1 sec without any repetitive stimulus and averaging them just like in traditional ERP to get a stimulus independent ERP waveform b) we can have a repetitive sound stimulus say every 1 sec and average the square of the waveform over the trials and subtract the square of the ERP calculated in usual manner. the resulting waveform will be reflective of noise.
The idea is that a waveform that is stimulus-independent / noise driven may be equivalent in value to resting-state fMRI procedures and the components of such waveforms may be of some help in delineating one person from another based around neural speed etc.
I want to find out if the concept already exists or makes sense?
