> fMRI takes a lot of post-processing with complex statistics to produce any kind of useful information.

So does EEG. The reason EEG is closer to real-time than fMRI is because of the sampling rate. With fMRI, .9 Hz is considered quite good. For EEG, 2000 Hz is considered standard.



Standard? 2000 Hz sampling rate may be used with intracranial electrodes.

If the EEG is measured from the scalp 200-250 Hz sampling rate is usually good enough. It enables EEG recordings up to 80-90 Hz. Most clinical uses are interested EEG below 40 Hz.


My mistake: I got mixed up and reported standard sampling rates for MEG.

You are, of course, correct.


Thanks for the clarification. I've only worked with fMRI, so wasn't aware of the ins and outs of EEG processing despite being aware of the spacial / temporal resolution difference. It makes this method even more suspicious!
