In a way, yes. It is more of a good inference of what I was refering to.
It does fit well, and I do not find it at all disagreable. It reveals
the "neuron generates random noise" from a new perspective.

The "random noise" can be viewed as dissonance; a harsh,
disagreeable combination of sounds. The disagreeable
combinations may be what your dreaming theory is trying
to resolve. Dischord does not have to build up from "random"
frequencies, it can build up from "random" tones of an
existing scale of frequencies. We can get carried away here
and start seeing "tuning" to a scale, or "tuning" to a chord, and
so on. There may be something useful here, I don't know.

I just think your "random noise" is a place holder in your
theory, and could bear some closer scrutiny that might
provide more insights. And if we find a mechanism that
provides emergent properties that appear like the above,
then all the better. It is that particular mechanism used in
a neuron that is interesting.

Whoa there. For a naive view, this is ok. Brainwaves and neuron
wave trains are two different things. The "unique waves" holds
some promise. Perhaps a Fourier analysis can show this
relationship, but it looks like a tough nut to crack. But I wouldn't
recommend pursuing brainwaves as information at the neuron
scale. Perhaps there is some entrainment value that might
support the "out of tune" view.

I'd have to throw out this description, and rework it for it
to make more sense to me. How about:

  Perhaps we can visualize an apple in our mind because the
  [unique waves, a chord,] of the apple's image is in memory.
  [Strike the same chord] and [that chord is] received by the same
  neurons whose job is to transmit images from our eyes into
  our brain.

Close enough, I was restricted by your grammer. :)

Of course they would, if viewed as above.

I concur.

Hope this helps,
