EEG Test using frontal lobe only

General Discussion
1

I’m trying to figure out if there is a test which can be done using only frontal lobe positions (Fp1, Fp2 or even F3, F4) to confirm EEG?

For example, getting alpha peak with eyes open/closed from occipital lobe (O1, O2).

Is there a task which can be completed using frontal channels only to confirm that the signal is EEG?

One option is detecting increased delta waves in F3 (Dorsolateral Prefrontal Cortex) using the Stroop test. Apparently there should be increased delta wave activity for in-congruent stimulus (i.e. different ink colour with different word of colour).
However, I haven’t been able to find a paper which directly states that this result occurs consistently.

Does anyone have a reference for such a test?

Interesting question @mark.o.s. I would think that an ERP test might be easier to arrange than a Stroop test, since ERPs are very well-documented in the EEG literature, and there are even sample ERP-detection setups in some free EEG software such as OpenViBE. See http://openvibe.inria.fr/recording-erps/ and http://openvibe.inria.fr/openvibe-p300-speller/.

Another simpler approach would be to check the power spectrum of the signal and see if it looks roughly like what you should be getting from an EEG.

What’s your use case?
