[Eeglablist] Open online discussion: How Do Cable Theory and AMPA/GABA Balance Compare in Their Contributions to 1/f?

[Makoto Miyakoshi]

Hello 1/f people,

Gin Estrella Cruz and I will meet online to discuss whether it is possible
to quantitatively compare the contributions of cable theory and AMPA/GABA
(i.e., E/I) balance to EEG's 1/f power distribution. At this point, I do
not know whether such a comparison is feasible. Anyone is welcome to join
if the timing works, I'd love to hear your opinions and advice. Since there
is a 12-hour time difference between us, the meeting time is a bit awkward.

To provide a bit of background, since the publication of the original FOOOF
paper, the idea that a flatter or steeper 1/f slope in the EEG power
spectral density reflects excitatory/inhibitory states appears to have been
overgeneralized. However, the 1/f-like behavior of EEG is an intrinsic
property predicted by cable theory. If there are two contributors (at
least) to 1/f-ness, they should be compared quantitatively to determine
which contributes more.
