You are saying that there is some monad in my head and that monad is me?

Yes.

I think a concrete example of a quantum-monadological hypothesis is in order. The best-known quantum-mind theories revolve around microtubules, so let's start there.

Orthodox cognitive neuroscience revolves around synapses and action potentials. But let's suppose Stuart Hameroff is right and microtubules are relevant as well, and are not just structural molecules. Maybe there are quantum-entangled mobile electrons in the shell of the microtubule, they feel the action potential, and they affect the binding of microtubule-associated proteins, i.e. let's suppose they are causally relevant to neuronal information processing, as they had better be if they are going to be the locus of consciousness. So, some subpopulation of microtubules, in some subpopulation of neurons, contains a big set of entangled electrons - and that is the monad that is you.

Although I have described it as a "set of entangled electrons", it is to be regarded as elementary because entangled objects no longer have independent individual states - they are more like aspects of a bigger thing (at least under the interpretation of quantum theory I'm using). Mathematically, it has a large number of degrees of freedom, and I suppose that in reality, those degrees of freedom are busy being your conscious thoughts, perceptions, and so forth.

Does that make things clearer?

I certainly know about David Chalmers's work and I generally agree with it. I just think we need to go even further and say, not just that "raw sensory qualities" aren't present in physics as normally conceived, but that they are bound together in consciousness in a way which suggests an underlying ontological unity beyond that possessed by a collection of spatial parts.
