[Eeglablist] average for frequency power scalp maps

[Ana Navarro Cebrian]

Dear all,

I have been using the average as my reference for years. I am now really
interested in getting the most reliable frequency power scalp maps and
would like to know what people's thoughts are about the best reference to
use for this. I was just looking at Yao, Wang, Oostenveld et al., 2005,
paper and it has made me doubt about the use of the average for power maps.
I may also end up looking at frequency correlations between channels.

Thank you in advance for any advice.
Best,
Ana
