| I think the pop-sci writer simply didn't choose a good wording
| - the original paper is simply about how the (consciousness-
| orchestrated?) synchronized activities of millions of neurons
| may be linked to "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".
|
| When we don't have a way to define consciousness and its (let's
| called it) orchestration, the notion of "communication" is
| none-sensible. It's like if we look at Shor's algorithm, its
| BQP efficiency isn't really due to any "communication" among
| the q-bits - but more as a kind of "probabilities collapsing"
| as they go through these quantum gates.
|
| Td;dr I think the phys.org writer is just trying to make it
| sound more exciting by unfortunately using a miss-leading word
