[Eeglablist] Fwd: The first official OneOverF online meeting

Sat Feb 14 00:38:54 PST 2026

Dear Makoto,

Thank you for arranging and chairing this meeting, it has been a very
positive experience to see so many scientist coming together from different
fields. Also a big thank to all the partners that have actively contributed
and all those that attended!

I find Athena's idea really pertinent to our cause and an excellent
starting point.  I would thus like to join the working group and contribute
to literature analysis and be part of a manuscript that openly verbalizes
the issues-problems surrounding the determination of aperiodic elements and
their significance in neurophysiological research. I think this is
something that is currently missing from the literature and the combined
force of so many scientist is a leap forward and a service to the
community. I am thus very excited.

On this front, I propose that we should create a join space where ideas
could be elaborated and interested individuals could, for a start, write a
small two to three paragraphs text on a chosen issue as discussed. I
believe talking about the origins (what is represents) of LFP-EEG and the
new ideas in the field is something important and then extending to what
the aperiodic means in terms of physiology. To remind everyone some
elements discussed in our meeting (to name a few,  Spatial Averaging, Low
pass dendritic filtering, multiplicative and additive spectral theories,
infra-slow soma-dendritic calcium currents, Fourier transforms of fast and
slow synaptic components). Once the few first texts  exist then the picture
of what can be written and the directions will reveal it self!

I would also like to play the devils advocate on the interpretation of
aperiodic exponents as proxies for excitation-inhibition balance (E/I
balance). On this role I will take the side of those that believe that
aperiodic exponent estimations follows E/I balance. That does not mean that
aperiodic exponent does not follow something else too and thus is not
exclusively bound as a direct proxy of E/I or that it points out to the
causal root of the changes (i.e., implying causality). For instance, the
changes in the aperiodic exponent seen in children related to axonal
myelination (discussed with Makoto ) can be interpreted as secondary to
myelination alterations and are indirectly related to E/I balance through
changes in presynaptic terminal activity. Within this context, aperiodic
component determination still captures a functional deficit (i.e., synaptic
transmission alterations) but fails to determine the roots cause of those
changes and can thus E/I balance disturbance can be seen as an
epiphenomenon secondary to the real cause which is myelination alterations
(e.g. Schwann cell loss due to neuroinflammation).

All thoughts welcome

Antonios Dougalis
