I've had this exact insight and I think it is the case. I'll take it even further. There are delays in propagation (duh). Because of this, the loops of neurons are resonant with certain frequencies of firing rates. Perhaps my favorite neural loop is the one that exits our skull and then reenters through the acoustic medium. If you put your speech into a microphone, through a delay line, then back into your ears it completely kills your ability to talk. https://speechjammerapp.com/ https://speechjammerapp.com/ A brain is a mechanical system resonant with abstract concepts.
