[ExI] are qualia communicable? Was Why stop at glutamate?

Another even deeper mystery that the communicability of qualia is how the
brain creates an I.
If you think about it, somehow the qualia is "communicated" among the
100,000s or even millions of neurons that are needed to
experience something like red. By the way, there was some time ago some
talk about "mother neurons" or single neurons that were activated when a
particular face was shown, almost implying we have in our brains a neuron
that activates when we see Brad Pitt. I'm not sure what is the status of
that line of research (I will look it up) but I don't think any experience
is associated with the activation of a single neuron.

Anyway, I'm pretty sure that when we experience something millions of
neurons are involved.
Jason, given you know so much about consciousness, how do these neurons
communicate to each other the experience of red (or anything else)? Somehow
millions of individual entities come together and say "I see red". I think
this phenomenon is even more important to understand than qualia.
Understanding of this phenomenon comes first because somehow there is some
sharing and integration of experience among these neurons. The qualia are
indeed communicated among these neurons at least. There is no point to talk
about qualia if we don't understand how an I is created by the brain in the
first place.
How the activity of many becomes the experience of an I?
