[Eeglablist] Fwd: The first official OneOverF online meeting

[Gyurkovics, Mate]

I think that is a fair summary, Doug - while the broadban part of the spectrum is likely to be determined by multiple mechanisms, there is no scenario in which it can be ignored when trying to estimate narrowband power. In fact, there are several scenarios where it's clearly not just noise and will systematically shift with cognitive processes, meaning that it's not just a nuisance variable but a confound (from the POV of oscillatory analyses).

Best,
Mate

Tárgy: Re: [Eeglablist] Fwd: The first official OneOverF online meeting

Hi all,

Thanks to everyone for organising and running the talk. Time zone issues
prevented me from attending, but I like the directions for the proposed
projects.

I'm happy to help out with a potential mechanism paper and the additive vs.
multiplicative paper.

My sense is that, despite a lot of initial optimism, a nice, clean-ish
mechanism will be elusive or very context-specific (perhaps some task-based
shifts are due to E:I balance, while age and pathology-related differences
have some other mechanism). That said, even if there isn't a single
mechanism like E:I balance, the systematic variation and slope and related
measures we're seeing across a range of contexts still poses a significant
challenge for any measure that ignores the broadband.

Doug
