Hello,

I'm trying to measure EEG (dry electrode / bi-polar / single channel) on frontal pole region (Fp1, Fp2, Fpz as right lag). After I get power spectrum, the power spectrum shows dominating frequency of ~4Hz (delta wave range) even for awake state.

  • Even ear lobe as right lag, get the same result.

I think the power spectrum should show dominating frequency of ~11Hz (alpha wave range) for awake state, for normal adult. Would the position of electrode be wrong ? or muscle artifacts ?

OR is there any reference for frontal pole EEG acquisition ? Can you guys please help me out ?

Thank you !

Hi Kisoong, Need a little more information. Would you mind sending me a figure, some details on how you are computing and which subject set you are looking at? You can email me at ddean@research.bwh.harvard.edu. Best, Dennis

I would love to send you your data but I only have a Resmed 10 Elite CPAP and it does not provide that information.

Hello Again,

If I interpret the comment. The question is regarding your own data. The goal of this forum is to answer questions pertaining to data hosted on this site. You might consider posting the question on the Linkedin EEG Signal Processing Group. Most questions received several responses within a few hours.

Best, Dennis
