Thanks, this make sense now, and it is associated with EEGLAB tutorial.

No worries I know that you're not the author. I didn't contact any of the
others about the issue I mentioned  because I know they will direct me to
the list. Although you're a post-doc and you have a good experience,  the
authors should also keep supervising the list regularly especially with
aspects related to their design and tutorial.

I highly appreciate your effort dear Makoto for getting the responsibility
answering our questions. All the best to you.

Thanks.
Jason

But the reason behind my question is that I observed in EEGLAB tutorial
(Chapter 08: Plotting ERP images) that is located in the link:

concentrated over the central occipital scalp".

consequently? In other words, if I'm interested studying Theta band, can I
consider 6Hz to be its value, and 10Hz as a value of Alpha, while 22Hz for
Beta?
