Could the brain be using electromagnetic fields to communicate between hemispheres — the electromagnetic field theory of consciousness?

First, the corpus callosum is not the only bridge between the left and right hemispheres of the brain. There is also the anterior commissure and the thalamus which could be used as an alternate pathway for communication.
Secondly, it should be somewhat expected that there would be 'synchrony' even if there was no direct connection between the left and right hemisphere. If both the left and right hemispheres are functionally similar, and are presented with the same stimulus (or lack thereof,) there would be little reason to see a major differences in their respective activity.
But I'm no neuroscientist, and neither are you. So, it's best not to jump the gun and use premature research to justify our own metaphysical beliefs.
I'm just here though. I'd love there to be some weird quantum phenomena to explain consciousness-- but so far I have yet to see sufficient evidence (aside from the existence of my own subjective experience of reality) to demand such a thing to explain how a brain functions.
Edit: Also googled later and found that fMRI's temporal resolution is very poor, and it'd be quite impossible to see if there is any communication between the two hemispheres using that technology alone. fMRI's images are over a long period of time, like a time-lapse photograph, so you don't know what-fired-when, and thus one cannot see if one hemisphere's activity caused activity in the other hemisphere.
