No. There's no evidence for that. There's an incredible mountain of evidence supporting the idea that neuronal action potentials are. The currents in neurons aren't even in the direction of the action potential propagation. They're perpendicular to it and only over a handful of tens of nanometers. Yes, the substrate of our macroscopic reality is dominated by electromagnetics but the brain isn't a very conductive place.
- RhodoYolo 6y agobut it begs the question; why? Obviously there is a biological necessity for these forms of propagation. I remember reading an old neuroscience textbook that said glial cells were purely support cells but they are finding a-lot of emergent phenomenon there as well.
- phs318u 6y agoNot finding an obvious "use" for something doesn't mean it doesn't have one. Especially when that thing has survived millions of years of evolutionary pressure to preserve useful stuff and cull useless stuff. Remember "junk DNA"? Turns out it wasn't junk. Anybody calling "useless" any of the outputs of nature's exquisite forge is likely to be proven wrong.
