One of the key limitations I find are the 'metaphors we live by'. They are useful and then we need to build on them.

One such is the model of a very basic electric circuit, as a model for neuronal activity.

We'll get there.. I'm sure.

..in hydroelectrodynamics, all the way to more empirical work on endogenous electric fields, the evidence is there.

Not to mention that the brain itself is endowed with continuum properties, given it's nature, one of which are oscillations. It is a noble pursuit to see how much effect they have.

I'd agree. There is a lot of work showing not just correlation between oscillations and function, but the mechanistic drive of electric fields in biomimetic media and neural tissue. But this beyond a BlueSky post.

From Poynting vectors in electrodynamics, to ferroelectric effects..

I do love me some martial arts analogies.. 😅

Me too. :-(
