Consciousness within the brain hinges on the synchronized activities of millions of neurons, but the mechanism responsible for orchestrating such synchronization remains elusive. In this study, we employ cavity quantum electrodynamics (cQED) to explore entangled biphoton generation through cascade emission in the vibration spectrum of C-H bonds within the lipid molecules' tails. The results indicate that the cylindrical cavity formed by a myelin sheath can facilitate spontaneous photon emission from the vibrational modes and generate a significant number of entangled photon pairs. The abundance of C-H bond vibration units in neurons can therefore serve as a source of quantum entanglement resources for the nervous system. The finding may offer insight into the brain's ability to leverage these resources for quantum information transfer, thereby elucidating a potential source for the synchronized activity of neurons.
I think the use of quatum mechanics here, is like 'god(s)' was/were used in the past for explaining things we do not understand or seem magical.
So, I was given an example of another quantum effect as an example. If there is some entanglement in nervecells, it might as well occur in plant cells, because they have a common ancestor.
These kind of articles wash over the signal noise ratio. Your phone does pick-up WiFi signals from tens of kilometer away, yet you hardly ever establish a connection with them, because there are so many other stronger signals. Only in some very specific setup is this possible, like we are still able to communicate with the voyager probes, one of which is now more than a lightday away.
There are some electrical synapses (gap junctions) between neurons and between astrocytes (which are a key part of computation based on more recent research).
Also, the electromagnetic field around the cells influences cell activity, and that field has various types of waves that appear to be specific to different types of activity (still unknown if it's a cause or an effect).
No one in this article guesses at what role it would play.
